Abstract

I forbindelse med dambrug på søterritoriet, ved opdræt af laks og ørred, forekommer der lakselus, der, hvis disse forekommer i større mængder, kan påføre dambruget meget store tab. Bekæmpelse af lakselus skal ifølge myndighedskrav de fleste steder finde sted ved biologisk bekæmpelse, med parasit æder fisk. Sådanne parasitædere er imidlertid meget sky, og søger skjul når de fordøjer indtagne lakselus, sådanne skjul findes naturligt på bunden havbunden, eller bunden af det søterritorie hvor dambruget er lokaliseret. Yderligere tabes der mange af disse nyttige parasitædere, når laksen pumpes over i transportskibe, hvilket medfører økonomiske tab for dambruget. Der angives til afhjælpning heraf et parasitæderskjul (6) i form af en indeslutning, hvis bund er indrettet med kunstig havbund, og hvis sider omfatter åbninger (24, 26) der er afspærrelige med et arreterbart skydespjæld (28). Parasitæderskjulet (6) eller et antal heraf anbringes jævnt fordelt over dambrugets overflade, og i den dybde hvor laksen/ørrederne typisk vil befinde sig. Herved opnås en effektivitetsforøgelse af parasitæderne, og reduceret tab af samme idet disse under overpumpning af laksen, kan indespærres i skjulet (6).In connection with aquaculture on the lake territory, when salmon and trout are raised, salmon lice occur, which, if these occur in large quantities, can cause very large losses to aquaculture. Controlling salmon lice, according to government requirements, must take place in most places by biological control, with parasite eating fish. However, such parasite eaters are very shy and seek shelter when they digest ingested salmon lice, such sheds are naturally found on the bottom sea floor, or the bottom of the lake territory where the pond farm is located. Furthermore, many of these useful parasite eaters are lost when the salmon is pumped into transport vessels, resulting in financial losses for the aquaculture industry. To remedy this, a parasitic sheath (6) is provided in the form of a containment whose bottom is arranged with artificial seabed and whose sides comprise openings (24, 26) which are interlockable with an adjustable slider (28). The parasitic sheath (6) or a number thereof is evenly distributed over the surface of the aquaculture and at the depth where the salmon / trout will typically be. In this way, an increase in efficiency of the parasite teats is achieved and reduced losses of the same as these during overpumping of the salmon can be confined to the shed (6).

I forbindelse med dambrug på søterritoriet, ved opdræt af laks og ørred, forekommer der lakselus, der, hvis disse forekommer i større mængder, kan påføre dambruget meget store tab. Bekæmpelse af lakselus skal ifølge myndighedskrav de fleste steder finde sted ved biologisk bekæmpelse, med parasit æder fisk. Sådanne parasitædere er imidlertid meget sky, og søger skjul når de fordøjer indtagne lakselus, sådanne skjul findes naturligt på bunden havbunden, eller bunden af det søterritorie hvor dambruget er lokaliseret. Yderligere tabes der mange af disse nyttige parasitædere, når laksen pumpes over i transportskibe, hvilket medfører økonomiske tab for dambruget. Der angives til afhjælpning heraf et parasitæderskjul (6) i form af en indeslutning, hvis bund er indrettet med kunstig havbund, og hvis sider omfatter åbninger (24, 26) der er afspærrelige med et arreterbart skydespjæld (28). Parasitæderskjulet (6) eller et antal heraf anbringes jævnt fordelt over dambrugets overflade, og i den dybde hvor laksen/ørrederne typisk vil befinde sig. Herved opnås en effektivitetsforøgelse af parasitæderne, og reduceret tab af samme idet disse under overpumpning af laksen, kan indespærres i skjulet (6).In the case of aquaculture on the lake territory, when salmon and trout are raised, salmon lice occur, which, if these occur in large quantities, can cause very large losses to aquaculture. Controlling salmon lice, according to government requirements, must take place in most places by biological control, with parasite eating fish. However, such parasite eaters are very shy and seek shelter when they digest ingested salmon lice, such sheds are naturally found on the bottom seabed, or the bottom of the lake territory where the pond farm is located.

Den foreliggende opfindelse angår en indretning til effektivisering af bekæmpelse af lakselus i dambrug, navnlig dambrug på søterritoriet. Opfindelsen angår endvidere en fremgangsmåde til effektivisering af bekæmpelse af lakselus i nævnte dambrug, ved anvendelse af indretningen ifølge opfindelsen.The present invention relates to a device for streamlining the control of salmon lice in aquaculture, in particular aquaculture in the lake territory. The invention further relates to a method for improving the control of salmon lice in said fish farm, using the device according to the invention.

I det følgende vil betegnelser som dambrug, havdambrug, skulle forstås som dambrug der er arrangeret på søterritoriet, det vil sige på havet, i fjorde, eller i større søer. Når der i det efterfølgende anvendes betegnelsen parasitter, vil dette omfatte alle former for parasitter i nævnte dambrug, herunder lakselus. Når der i det efterfølgende anvendes betegnelsen parasitædere, skal dette forstås i bredest mulig forstand, herunder også som læbefisk.In the following, terms such as aquaculture, marine aquaculture, should be understood as aquaculture arranged on the lake territory, that is, at sea, in fjords, or in larger lakes. In the following, when the term parasites is used, this will include all kinds of parasites in said aquaculture, including salmon lice. In the following, when the term parasite eaters is used, this should be understood in the broadest possible sense, including as a lip fish.

Sådanne dambrug, udgøres af poseformede netafgrænsninger placeret på søterritoriet eller i fjorde, i hvilke opformeres større populationer af laks eller ørred til siagtestørrelse. Netafgrænsningerne er typisk kegleformede net, hvis øverste sidekanter er fastgjort til en flydende konstruktion, og hvor nettet hænger frit i vandet over hav/fjord bunden, ca. 90% af laksen i posen befinder sig indenfor en dybde på 0-6 m.Such aquaculture farms are made up of bag-shaped net boundaries located on the lake territory or in fjords, in which larger populations of salmon or trout are grown in size. The net boundaries are typically cone-shaped nets whose upper side edges are attached to a floating structure and where the net hangs freely in the water above the sea / fjord bottom, approx. 90% of the salmon in the bag is within a depth of 0-6 m.

I nævnte dambrug, forekommer der en stor population af laks, og det kan derfor ikke undgås, at en så stor population af laks tiltrækker lakselus.In said aquaculture, there is a large population of salmon, and so such a large population of salmon cannot be attracted to salmon lice.

Lakselusene sætter sig fast på laksenes skind, og spiser af laksens beskyttende slimhinde, skind og suger laksens blod. Dette åbner for andre infektioner, eksempelvis bakterier, svamp, og indvirker tillige på den osmotiske saltbalance i laksen. Desuden medvirker lakselusene til nedsat vækst af laksene. Lakselus er den største årsag til tab af laksefisk ved opdræt, det antages at lakselusene medfører tab i Norge på samlet NOK 500 mio. årligt (2016).The salmon lice get stuck on the salmon's skins, and eat from the salmon's protective mucosa, skins and suck the salmon's blood. This opens up for other infections, such as bacteria, fungi, and also affects the osmotic salt balance in salmon. In addition, salmon lice contribute to reduced growth of salmon. Salmon lice are the leading cause of loss of salmonids during breeding. It is assumed that salmon lice cause losses in Norway totaling NOK 500 million. annually (2016).

Lakselusen trives bedst i saltvand, hvor den formerer sig hele året, og bedst når temperaturen øges i foråret, og trives dårligere i takt med lavere saltkoncentration i vandet, og hvor en laks vandrer fra saltvand til ferskvand, tabes lusene helt efter ca. 14 dages ophold i ferskvand.The salmon lice thrive best in saline where it propagates throughout the year, and best when the temperature rises in the spring, and thrives less as a lower salt concentration in the water, and where a salmon migrates from saline to fresh water, the lice are completely lost after approx. 14 days stay in fresh water.

Hvor laksefarmene er placeret i fjorde, med tilstrømning af ferskvand, dannes der springlag, idet saltvand har større massefylde end ferskvand, det vil sige atWhere salmon farms are located in fjords, with inflow of fresh water, spring layers are formed, with salinity having greater density than fresh water, that is to say

DK 2017 00266 A1 typisk i den øverste meter vanddybde, er forekomsten af lakselus lille, men herefter vokser den i takt med saltindholdet i vandet, men eftersom laksen befinder sig mellem 0 og 6 m dybde, kan angreb af lakselus ikke undgås.Typically in the upper meter water depth, the occurrence of salmon lice is small, but then grows in line with the salt content of the water, but since the salmon is between 0 and 6 m depth, attacks of salmon lice cannot be avoided.

Veterinærmyndighederne har fastsat klare retningslinier for, hvorledes lakselusen skal bekæmpes, og sat grænser for, hvor mange lakselus der må forefindes pr. laks i dambrug. Bekæmpelse af lakselus med kemikalier, er ikke tilladt af hensyn til veterinære- og miljømæssige standarder.The veterinary authorities have set clear guidelines on how to combat the salmon lice and set limits on how many salmon lice can be found per day. salmon in pond farming. Combating salmon lice with chemicals is not allowed for veterinary and environmental standards.

Bekæmpelse af lakselus kan med fordel finde sted ved hjælp af parasitfisk, såsom læbefisk, der lever af lakselus, og anvendelse af denne biologiske bekæmpelsesmetode er blevet et lovkrav i flere lande, der har dambrug på søterritoriet på havet og i fjorde. Man opdrætter således læbefisk i salgsøjemed, til laksedambrug.The control of salmon lice can advantageously take place by means of parasitic fish, such as lepidoptera living on salmon lice, and the use of this biological control method has become a legal requirement in several countries that have aquaculture on the sea territory and in fjords. Lip fish are thus raised for salmon farming purposes.

Problemet er blot, at læbefisken er en sky bundfisk, og denne trives bedst, hvis den har skjul på bund med småsten, grus og tang, hvor den efter at have spist, søger tilflugt imellem måltiderne. Hvor laksedambrugene er placeret således, at der er stor vanddybde under laksefarmens net, vil læbefisken således have besvær med at finde skjul, hvilket medfører at forekomsten af denne ikke bliver tilstrækkelig i disse farvande, til at holde bestanden af lakselus på et acceptabelt niveau.The only problem is that the lip fish is a shy bottom fish, and this thrives best if it has hides on the bottom with pebbles, gravel and seaweed, where after eating it takes refuge in between meals. Thus, where the salmon farms are located so that there is a great depth of water under the salmon farm nets, the lip fish will have difficulty finding concealment, which means that its occurrence will not be sufficient in these waters to keep the stock of salmon lice at an acceptable level.

Der forekommer endvidere det problem, at når laksen fjernes fra dambruget, sker dette typisk ved at pumpe laksen over i tankskibe, der transporterer laksen til slagtning, eller til andre dambrug. Ved overpumpningen sker der det, at læbefiskene, som egentlig er en del af dambrugets drifts udstyr, om man så må sige, pumpes med sammen med laksen over i tankskibet, hvilket medfører, at dambrugsejeren mister en del af de meget nyttige læbefisk, der er en forudsætning for driften af dambruget. Det vil sige at der skal indkøbes nye læbefisk til erstatning for de som forsvinder med laksen, når bassinet igen tages i brug.Furthermore, there is the problem that when the salmon is removed from the fish farm, this is typically done by pumping the salmon into tankers carrying the salmon for slaughter, or to other fish farms. During the over-pumping, it happens that the lip fish, which is actually part of the aquaculture's operating equipment, so to speak, is pumped along with the salmon into the tanker, which causes the aquaculture owner to lose some of the very useful lip fish that are a prerequisite for the operation of the aquaculture. This means that new lip fish must be purchased to replace those who disappear with the salmon when the basin is used again.

Det ville således være ønskeligt, om læbefiskene kunne opbevares i det niveau i bassin nettet i dambruget, hvor laksen opholder sig, idet dette ville forøge effektiviteten af læbefiskenes fjernelse af lakselus, og yderligere, at kunne reducere tabet af læbefisk, ved tømning af dambrugets bassiner for laks, ligesom en hensigtsmæssig transportmulighed for læbefiskene også er ønskelig.Thus, it would be desirable if the lip fish could be stored at the level of the pond net in the fish farm where the salmon resides, as this would increase the efficiency of the lip fish's removal of salmon lice, and further, be able to reduce the loss of lip fish, by emptying the fish tank basins. for salmon, just as an appropriate transport option for the lip fish is also desirable.

DK 2017 00266 A1DK 2017 00266 A1

Det er ved opfindelsen indset, at dette er muligt ved i det mindste et mobilt skjul, i form af en indeslutning, hvis sider, i en afstand over indeslutningens bund, har åbninger der ved arreterbare skydespjæld eller låger er afspærrelige, igennem hvilke åbninger parasitæderne kan passere ud og ind, hvor indeslutningen omfatter ophængningsfaciliteter der samvirker med kantinstallationer på dambruget, eller med flyderinge der samvirker med dambrugets sideafgrænsninger, hvor indeslutningen ved ophængningsfaciliteterne fastholdes i en på forhånd udvalgt dybde under overfladen, og hvor beholderens bund omfatter et lag af kunstig havbund.It is recognized by the invention that this is possible by at least one mobile concealment, in the form of an enclosure whose sides, at a distance above the bottom of the enclosure, have openings which are lockable by adjustable sliders or doors through which openings the parasite heads can pass out and in, where the containment comprises suspension facilities that cooperate with edge installations on the dam, or with floating rings which cooperate with the side boundaries of the dam, where the containment at the suspension facilities is maintained at a pre-selected depth below the surface and where the bottom of the container comprises a layer of artificial seabed.

Herved opnås det, at parasitæderne efter de har spist sig mætte af lakselus, kan finde skjul i umiddelbar nærhed af det sted i dambruget, hvor laksene befinder sig, og når de igen er sultne, hurtigt kan finde vej til de laks der er befængt med lakselus.In this way it is achieved that, after eating the salmon lice, the parasite traps can find shelter in the immediate vicinity of the place in the pond farm where the salmon are, and when they are hungry again, can quickly find their way to the salmon infested with lice.

Yderligere rummer indeslutningen den fordel, at skydespjældene eller lågerne kan lukkes når laksene pumpes over i tanke i de transportskibe der transporterer laksen til slagtning, eller andre dambrug.Furthermore, the enclosure has the advantage that the sliders or lids can be closed when the salmon is pumped into tanks in the transport vessels carrying the salmon for slaughter, or other pond use.

Som følge af læbefiskens skyhed, vil uro i og omkring bassinet med laksen medføre, at læbefiskene søger ind i skjulet, det vil sige, at når laksen skal bortpumpes, kan læbefiskene relativt let skræmmes ind i skjulene, hvorefter åbningerne i beholderne blokeres, manuelt, eller ved aktuatorer, hvorved tabet af læbefisk ved overpumpning af laksen til et tankskib reduceres betragteligt, og derved sparer dambrugsejeren penge, idet der ikke så ofte bliver behov for indkøb af nye læbefisk.Due to the shallowness of the lip fish, unrest in and around the basin with the salmon will cause the lip fish to enter the shed, that is, when the salmon is to be pumped away, the lip fish can be relatively easily frightened into the sheds, after which the openings in the containers are blocked manually. or by actuators, whereby the loss of lip fish by overpumping the salmon to a tanker is considerably reduced, thereby saving the fish farm owner money, as new lip fish is not often needed.

Det vil sige, at de parasitædere der befinder sig i skjulet, midlertidigt indespærres, med mulighed for at lukkes ud i dambruget på ny, når overpumpningen af laks er afsluttet. Derved mister dambruget ikke så stor en mængde parasitædere, og disse vil være klar til at fortsætte med at æde lakselus, når de slippes ud af skjulet.That is, the parasite eaters that are in the shed are temporarily confined, with the possibility of being shut out in the pond farm once the salmon overpumping is completed. As a result, the pond farm does not lose as large a number of parasite eaters, and these will be ready to continue to eat salmon lice when released from the shed.

Ved anvendelse af skjulet ifølge opfindelsen opnås udover ovenstående fordele af mere økonomisk/praktisk karakter, også en betragtelig forøgelse af velfærden for de fisk der befinder sig i dambruget, eftersom lasken/ørreden der befinder sig i dette vil få hyppigere besøg af de nyttige parasitædere, idet disse ikke behøver at svømme så langt for at finde skjul, og parasitæderne kommer til at leve i umiddelbar nærhed af de sted, hvor deres hovedfødekilde, lakselus, befinder sig,By using the shed according to the invention, in addition to the above advantages of a more economical / practical nature, a considerable increase in the welfare of the fish that are in the aquaculture is also obtained, since the worm / trout found in this will receive more frequent visits by the useful parasite eaters. since they do not need to swim too far to find shelter, and the parasites will live in the immediate vicinity of where their main food source, salmon lice, is located,

DK 2017 00266 A1 alt i alt betyder opfindelsen, at alle individer der befinder sig i dambrug, der benytter skjulene ifølge opfindelsen, får forøget deres velfærd betragteligt. Yderligere medfører den mere effektive bekæmpelse af lakselusene med parasitæderne, der ved opfindelsen er muliggjort, at anvendelse af antibiotika, og andre kemiske bekæmpelsesmidler til bekæmpelse af lakselus, der kan betegnes som miljøfremmede stoffer, som kan være til skade for andre levende organismer i havet eller på søterritoriet, kan minimeres, måske endda helt undgås, hvilket må betragtes som værende en stor gevinst for vandmiljøet.All in all, the invention means that all individuals who are in the aquaculture industry using the sheds according to the invention will increase their welfare considerably. Furthermore, the more effective control of the salmon lice by the parasite teats, which by the invention has made it possible to use antibiotics and other chemical pesticides to control salmon lice, which can be termed as environmentally harmful substances which may be detrimental to other living organisms in the sea or on the territorial sea, can be minimized, perhaps even completely avoided, which must be considered a great gain for the aquatic environment.

Det foretrækkes at et antal af mobile skjul placeres fordelt over et netposebassin, i en dybde på mellem 0,5-10 meter, typisk 1 - 8 meter, og foretrukket 3 til 6 meter.It is preferred that a number of mobile sheds be placed over a net bag pool, at a depth of between 0.5-10 meters, typically 1-8 meters, and preferably 3 to 6 meters.

Herved opnås det, at parasitædernes skjul netop kan placeres i den dybde, hvor forekomsten af lakselus er størst, hvilket forøger parasitædernes effektivitet, idet de ikke behøver at tilbagelægge så lang en strækning imellem deres skjul og laksene, der bærer lakselusene.Hereby it is achieved that the shelter of the parasite teats can be placed precisely at the depth where the occurrence of salmon lice is greatest, which increases the efficiency of the parasite teats, since they do not have to travel as long a distance between their hides and the salmon carrying the salmon lice.

Det foretrækkes endvidere, at skjulene anbringes i dambrugets bassiner med en afstand på ca. 3-15 meter, typisk 4-13 meter, og foretrukket 5-10 meter, altså jævnt fordelt over dambrugets overflade, og i den dybde hvor laksen typisk befinder sig i netposen, herved opnås det at læbefiskene er lige i nærheden af laksene hele tiden, og de kan efter at have spist sig mætte i lakselus, svømme ind i skjulet, fordøje og hvile sig, inden de på ny svømmer ud og spiser flere lakselus.It is further preferred that the sheds be placed in the reservoir basins at a distance of approx. 3-15 meters, typically 4-13 meters, and preferably 5-10 meters, evenly distributed over the surface of the fish farm, and at the depth where the salmon are typically in the net bag, this results in the lip fish being close to the salmon at all times and, after eating saturated salmon lice, they can swim into the hide, digest and rest before swimming out again and eating more salmon lice.

I den hensigt at skabe tryghed og skjul for parasitæderne indeni indeslutningen, kan bunden af denne være forsynet med kunstig havbund bestående af et lag groft sand, småsten og kunstig tang. Det foretrækkes yderligere af hensyn til bekæmpelse af bakterier m.m., at havbunden og den kunstige tang er varmebehandlet, og varmebehandles i forbindelse med periodisk rengøring indeslutningen.For the purpose of providing security and concealment to the parasites within the enclosure, the bottom of it may be provided with artificial seabed consisting of a layer of coarse sand, pebbles and artificial seaweed. It is further preferred for the control of bacteria, etc., that the seabed and artificial seaweed are heat treated and heat treated in connection with periodic cleaning of the enclosure.

Herved tilvejebringes trygge og gode opholdsmuligheder for parasitæderne, når disse skal fordøje de indtagne lakselus, og ved varmebehandlingen opnås det, at der ikke i den kunstige havbund opsamles sygdomsfremkaldende bakterier.This provides safe and good accommodation for the parasites, when they have to digest the ingested salmon lice, and in the heat treatment it is achieved that no disease-causing bacteria are collected in the artificial seabed.

Af hensyn til imødegåelse af opsamling af fækalier og foderrester på toppen af indeslutningen ifølge opfindelsen, foretrækkes det, at indeslutningens øvre afDK 2017 00266 A1 grænsning udgøres af en eller flere skrånende flader imellem kip og tagfod.In order to counter the collection of faeces and feed residue at the top of the enclosure according to the invention, it is preferred that the upper enclosure of the enclosure 2017 00266 A1 is constituted by one or more sloping surfaces between the chimney and the eaves.

Herved opnås det, at fækalier fra laksene i dambruget samt foderrester ikke ansamles så let ovenpå indeslutningen, hvilket er medvirkende til at reducere sygdomshsici.This results in the fact that faecal salmon from the fish farms as well as feed residues do not accumulate so easily on top of the containment, which contributes to reducing disease risk.

Af hensyn til at lette betjeningen af skydespjældene/lågerne ved indeslutningens åbninger, kan disse være aktuatordrevne, eller manuelt styrede ved wiresystemer, der henholdsvis hæver skydespjældene/lågerne fra deres passive position hvor spjældende/lågerne nedadvendende kant er hvilende imod første stop, til en aktivposition, hvor åbningerne i indeslutningen er blokerede, og skydespjældet placeret i og en position hvor den opadvendende kant af skydespjældet er beliggende nær andre stop, hvor skydespjældet er arreteret i en wire udløselig låseanordning omfattende to låse placeret på modstående sider af indeslutningen, alternativt diamentralt modsat.In order to facilitate the operation of the sliders / doors at the openings of the enclosure, these may be actuator driven, or manually controlled by wiring systems which respectively raise the sliders / doors from their passive position where the slider / doors downward edge is resting against the first stop, to an active position wherein the apertures in the enclosure are blocked and the slider located in and a position where the upward edge of the slider is located near other stops where the slider is arranged in a wire-releasable locking device comprising two locks located on opposite sides of the enclosure, alternatively diametrically opposite.

Herved bliver det muligt at betjene skydespjældene/lågerne fra dambrugets kantinstallationer, uden at være nødsaget til at hale hele skjulet op på kantinstallationen. Det vil sige at parasitæderne i forbindelse med overpumpning af laksen i dambruget til tankskibe, kan skræmmes ind i skjul i indeslutningen, og åbningerne til indeslutningen kan blokeres relativt hurtigt (under et sekund) ved træk i wiren, hvorved parasitæderne er fanget i indeslutningen indtil åbningerne på ny åbnes, ved deaktivering af låsen, og sænkning af skydespjældet/lågerne. Herved undgås det at parasitæderne pumpes med over i tankskibet sammen med laksen, og derved forbliver som en vigtig del af driftsmidlerne for dambruget, der kan benyttes ved udsætning af nye laks i dambruget.This makes it possible to operate the sliders / gates from the dam's edge installations, without having to lift the entire cover up on the edge installation. That is, the parasitic tendons associated with overpumping the salmon in the tank farm for tankers can be shrunk into shelter in the containment, and the openings for the containment can be blocked relatively quickly (under a second) by pulling the wire, whereby the parasitic traits are trapped in the containment until the openings opens again, by deactivating the lock and lowering the damper (s). This prevents the parasitic tufts from being pumped into the tanker along with the salmon, and thus remains as an important part of the farm's operating resources that can be used in the release of new salmon in the fish farm.

I den hensigt at lette transporten af indeslutningen ifølge opfindelsen, kan denne være indrettet med faciliteter eller øvrige støtteforanstaltninger, der medfører, at den er egnet til transport på en palleløfter eller en gaffeltruck. Herved bliver det muligt at benytte skjulet til transport af parasitæderne imellem deres klækkested/produktionssted og til dambruget, yderligere kan indeslutningen eventuelt også benyttes som klækkested for parasitæderne, således at disse bliver trygge og kendt med omgivelserne. Der kan ligeledes indeni indeslutningen, i niveau under spalteåbningerne placeres mindre skjul for parasitæderyngel, således ynglen i den førte levetid får et mindre og mere passende skjul. Ved at indeslutningen er forsynet med faciliteter der gør denne egnet til transport med palleløfter eller gafIn order to facilitate the transport of the enclosure according to the invention, it may be provided with facilities or other supporting measures which make it suitable for transport on a pallet truck or a forklift truck. This makes it possible to use the hide to transport the parasites between their hatchery / production site and to the pond farm. In addition, the enclosure may also be used as a hatchery for the parasites so that they become safe and familiar with the surroundings. Also, within the enclosure, smaller shelters for parasitic eagle fry can be placed at level below the slot openings, thus giving the fry a smaller and more suitable shed during its life. The enclosure is provided with facilities that make it suitable for transport with pallet lifts or gables

DK 2017 00266 A1 feltruck, vil det også være lettere at transportere og håndtere indeslutningen til rengøring og desinfektion etc.DK 2017 00266 A1 field truck, it will also be easier to transport and handle the containment for cleaning and disinfection etc.

Det skal understreges at selvom indeslutningen forsynes med nævnte faciliteter er denne på ingen måde bundet til at fremstå med nogen entydig geometri.It should be emphasized that although the enclosure is provided with said facilities, it is in no way bound to appear with any unique geometry.

I den hensigt at være i stand til at gennemføre en visuel kontrol af populationstætheden af parasitædere i indeslutningen, kan taget af indeslutningen omfatte et transparent område.In order to be able to visualize the population density of parasite eaters in the enclosure, the roof of the enclosure may comprise a transparent area.

Herved opnås der en mulighed for kontrol af mængden af parasitædere i indeslutningen/skjulet, dette fordrer dog, at indeslutningen er placeret således at der er adgang til det transparente område.This provides an opportunity for control of the amount of parasite eaters in the enclosure / hide, however this requires that the enclosure be positioned so that access to the transparent area is available.

I en anden udførelsesform af indeslutningen ifølge opfindelsen, hvor kontrol af mængden af tilstedeværende parasitædere i indeslutningen ønskes kontrolleret, uden at indeslutningen er halet op i en position hvorfra populationen kan kontrolleres visuelt, kan taget omfatte en sensor, der defekterer populationen af parasitædere i indeslutningen.In another embodiment of the enclosure according to the invention, where control of the amount of parasite eaters present in the enclosure is desired to be controlled, without the enclosure being tilted to a position from which the population can be visually controlled, the roof may include a sensor which defects the population of parasite eaters in the enclosure.

Dette er meget fordelagtigt, idet der herved åbnes mulighed for at populationen af parasitædere i indeslutningen kan kontrolleres uden at ændre på indeslutningens placering i dambruget, altså imens skjulet er i ro. Ved en ønsket population af parasitædere i indeslutningen, kan skydespjældet forskydes til den aktive position hvor åbningerne blokeres, hvorved parasitæderne er spærret inde i indeslutningen.This is very advantageous as it allows the population of parasite eaters in the enclosure to be controlled without changing the location of the enclosure in the pond, thus while the shed is at rest. At a desired population of parasite eaters in the enclosure, the slider can be shifted to the active position where the openings are blocked, thereby blocking the parasite eaters inside the enclosure.

I den hensigt at muliggøre en effektiv rensning af indeslutningen, herunder at kunne udskifte eller rense den kunstige havbund i indeslutningen, kan taget være aftageligt, alternativt er hængslet til indeslutningens side.In order to enable effective cleaning of the enclosure, including being able to replace or clean the artificial seabed in the enclosure, the roof may be removable, or alternatively the hinge to the enclosure side.

Herved opnås fuldstændig adgang til indeslutningens indvendige side, således at rengøring let kan udføres.This provides complete access to the inside of the enclosure so that cleaning can be performed easily.

I den hensigt at lette håndteringen af indeslutningen når denne hæves over dambrugets vandspejlsniveau, og samtidigt at være i stand til at opbevare levende parasitædere i indeslutningen, kan dettes sider i en afstand under åbningerne, omfatte en hulrække, men over indeslutningens bund, bestående af huller med en diameter der ikke tillader passage af parasiræderne.In order to facilitate the handling of the enclosure as it is raised above the water level of the aquaculture while being able to store live parasitic eaters in the enclosure, its sides at a distance below the openings may comprise a row of holes, but above the bottom of the enclosure, consisting of holes. with a diameter that does not allow passage of the parasites.

DK 2017 00266 A1DK 2017 00266 A1

Herved opnås det, at den vandmængde, der i indeslutningens nedsænkede position i dambruget, befinder sig i niveauet over hulrækken, vil sive ud gennem hullerne, men eftersom hulrækken er lokaliseret ovenover bunden af indeslutningen, vil der fortsat være tilstrækkeligt vand i indeslutningen til, at parasitæderne kan ånde. Dette medfører at indeslutningen ikke bliver så tung at flytte rundt med, og transporten heraf lettes derfor betydeligt.Hereby it is obtained that the amount of water which, in the submerged position of the containment in the pond use, is in the level above the hole row, will leak out through the holes, but since the hole row is located above the bottom of the housing, sufficient water will remain in the housing for the parasites can breathe. This means that the containment does not become so heavy to move around, and its transport is therefore considerably facilitated.

I den hensigt at sikre en let håndtering af indeslutningen imellem dennes placerede position i dambruget, og flyderingene, eller dambrugets sideafgrænsninger, kan wiresystemet for forskydning af skydespjældet bestå af en første wire, fastgjort til skydespjældets første ende, og en anden wire, fastgjort til skydespjældets anden ende, hvilke wirer i en afstand over indeslutningens tag er samlede i et samlepunkt, hvorfra en enkelt tredje wire der er løsbart tilsluttet samlepunktet, forløber opefter til et ophalesystem, og hvilket punkt omfatter yderligere omfatter midler for tilslutning af en ekstern løfteenhed.In order to ensure easy handling of the enclosure between its positioned position in the dam and the float rings, or the side boundaries of the dam, the wiring system for displacing the damper may consist of a first wire attached to the first end of the damper and a second wire attached to the damper. a second end, which at a distance above the roof of the enclosure, is assembled at an assembly point, from which a single third wire which is detachably connected to the assembly point extends upwardly to an uphole system, and which further comprises means for connecting an external lifting unit.

Fordelen herved er, at den første anden og tredie wire benyttes dels til hævning af skydespjældet, og dels til, når skydespjældet er lukket, til at ophale hele indeslutningen med sit indhold af kunstig havbund, vand og parasitædere, til en position hvorfra indeslutningen ved hjælp af andre løftemidler, eksempelvis en ekstern kran på et skib, kan tilsluttes den ekstra tilslutningsmulighed i samlepunktet, hvorved den første og anden wire kan afmonteres fra spjældet, ligesom ophængningsfaciliteterne imellem sideafgrænsningen på flyderingen eller dambruget og indeslutningen kan frigøres fra indeslutningen, og indeslutningen hejses op, eksempelvis på et skibsdæk.The advantage of this is that the first second and third wires are used partly to raise the damper and partly when the damper is closed, to retrieve the entire containment with its contents of artificial seabed, water and parasitic eaters, to a position from which the containment by means of of other lifting means, such as an external crane on a ship, can be connected to the additional connection option at the assembly point, whereby the first and second wires can be removed from the damper, and the suspension facilities between the side boundary of the float or the dam and the enclosure can be detached from the enclosure and , for example, on a ship deck.

I den hensigt at holde indeslutningen ifølge opfindelsen i en så fast og rolig position som muligt, kan ophængningsfaciliteterne udgøres af i det mindste tre liner/wirer, der forløber imellem fastgørelsesøjer på indeslutningens yderside, og tilslutningspunkter placeret på sideafgrænsningen på flyderingen og/eller på dambrugets sideafgrænsning.In order to keep the enclosure according to the invention in as firm and calm a position as possible, the suspension facilities may consist of at least three liner / wires extending between fastening eyes on the outside of the enclosure and connection points located on the side boundary of the float and / or the dam side boundary.

DK 2017 00266 A1DK 2017 00266 A1

Ved at anvende mindst tre fastgørelsespunkter, opnås der stabilitet for indeslutningen hvad angår dennes fysiske placering i dambruget.By using at least three attachment points, the stability of the enclosure as to its physical location in the pond farm is achieved.

I den hensigt at kunne frigøre skydespjældet/lågerne fra den aktive position til den passive, uden at skulle hæve indeslutningen til overfladen og indenfor manuel rækkevidde, kan låseanordningerne være indbyrdes forbundne med en fjerde wire, hvis midte er forbundet med en igennem en åbning i indeslutningens tag forløbende femte wire, der er fastgjort til en holdemekanisme på sideafgrænsningen på flyderingen eller på dambruget.In order to be able to release the slider (s) from the active position to the passive, without having to raise the enclosure to the surface and within manual range, the locking devices may be interconnected with a fourth wire, the middle of which is connected to a through opening in the enclosure. take progressive fifth wire attached to a retaining mechanism on the side boundary of the float or on the pond use.

Herved opnås den fordel, at såfremt der blot skal skiftes laks i dambrugets bassin, kan parasitæderne skræmmes ind i indeslutningen, og derefter kan skydespjældet lukkes ved at trække i den tredje wire, indtil skydespjældet er låst i låseanordningen, og parasitæderne er spærret inde. Herefter kan laksen overpumpes til skib, og nye fisk til opfedning kan udsættes i dambruget, hvorefter der trækkes i den femte wire for udløsning af låsemekanismen, og den tredje wire slækkes, således at skydespjældet sænkes til anlæg imod de første nedre stop. Fordelen herved at skydespjældet hviler imod de første nedre stop i den passive position er, at skydespjældets bevægelser følger indeslutningens ved bølgegang der måtte påvire sideafgrænsningen af flyderingen eller dambrugets sideafgrænsning. Det vil sige at parasitæderne forstyrres mindst muligt ved bølgegang omkring dambruget.Hereby, the advantage is obtained that, if only salmon is to be changed in the pond's basin, the parasites can be intimidated into the enclosure, and then the slider can be closed by pulling the third wire until the slider is locked in the locking device and the parasites are locked inside. Thereafter, the salmon can be pumped over to the ship and new fish for fattening can be exposed in the fish farm, after which the fifth wire is pulled for release of the locking mechanism and the third wire is extinguished, so that the slider is lowered for abutment against the first lower stops. The advantage of this being that the damper rests against the first lower stops in the passive position is that the movements of the damper follow that of the enclosure at a wave which may affect the lateral boundary of the float or the dam's lateral boundary. That is, the parasitic bodies are disturbed as little as possible by the wave around the pond farm.

I den hensigt at sikre at der ikke sker relative forskydninger imellem indeslutningens tag og dennes vægge, kan taget være fastholdt i position ved i det mindste en vertikalt orienteret tap, omfattende en gennemgående åbning for en låsebolt, hvilken åbning er placeret således, at taget når tværbolten er placeret i den gennemgående åbning, er presset an imod indeslutningens vægge.In order to ensure that relative displacements do not occur between the roof of the enclosure and its walls, the roof may be held in position by at least one vertically oriented pin, comprising a through-opening of a locking bolt, which opening is positioned so that the roof when the cross bolt is located in the through opening, is pressed against the walls of the enclosure.

Herved modvirkes relative forskydninger imellem tag og vægge i indeslutningen der kan skræmme parasitæderne.This will counteract relative displacements between roofs and walls of the enclosure that may frighten the parasites.

Af hensyn til bestandigheden af indeslutningen, hensynet til lav vægt, samt krav fra levnedsmiddelmyndighederne, foretrækkes det at indeslutningen, samt de dertil anvendte samlemidler, wirer, og ophængningssystem, udføres i et af levnedsmiddelmyndighederne godkendt plastmateriale og rustfrit syrefast stål godkendt til levnedsmiddelproduktion.In view of the durability of the containment, the consideration of the light weight, as well as the requirements of the food authorities, it is preferred that the containment, as well as the assemblies, cables and suspension system used for this purpose, be carried out in a plastic material and stainless acid approved steel approved by the food authorities.

En fremgangsmåde til effektivisering af bekæmpelse af lakselus et bassin iA method for streamlining the control of salmon lice in a basin

DK 2017 00266 A1 dambrug, navnlig dambrug på søterritoriet kan være kendetegnet ved følgende procestrin;DK 2017 00266 A1 aquaculture, in particular aquaculture in the lake territory may be characterized by the following process steps;

-anbringelse af en population af parasitædere samt vand i et eller flere skjul ifølge et hvilket som helst af kravene 1-18,- placing a population of parasite eaters as well as water in one or more sheds according to any one of claims 1-18,

-anbringelse af et antal skjul jævnt fordelt over overfladen af et bassin i dambruget, og i forskellig dybde indenfor intervallet mellem 0,5-10 meter, typisk 1 - 8 meter, og foretrukket 3 til 6 meter,- placing a number of sheds evenly distributed over the surface of a pond in the pond, and at various depths within the range of 0.5-10 meters, typically 1-8 meters, and preferably 3 to 6 meters,

-forskydning af skydespjældene til den passive position, hvorved åbningerne i indeslutningen er fri til passage af parasitædere.-shifting the sliders to the passive position whereby the openings in the enclosure are free for passage of parasite eaters.

Herved opnås det at parasitæderne har et skjul at gemme sig, der er placeret i den dybde, og position hvori laksene/ørrederne befinder sig i, imens de fordøjer de lakselus de har spist. Dette betyder at parasitæderfiskene ikke behøver st skulle tilbagelægge længere strækninger imellem deres skjul og laksene i dambruget, efter de har fordøjet de spiste lakselus.Hereby it is obtained that the parasites have a hide to hide that is located in the depth and position in which the salmon / trout are in, while digesting the salmon lice they have eaten. This means that the parasitic fish do not need to travel longer distances between their hide and the salmon in the pond farm after they have digested the salmon lice.

Fig. 1 er et perspektivbillede af et bassin 2 i et havdambrug omfattende flyderinge 4 i hvilke er ophængt skjul 6 for parasitædere i form af indeslutninger 6 ifølge opfindelsen. Bassinet 2 er båret af en sideafgrænsning 8, hvortil flyderingene 4 ved første forankringsliner 10 er fastgjort. Endvidere findes der andre positioneringsliner 12 imellem flyderingene 4, hvorved den indbyrdes afstand imellem flyderingene 4 fastholdes. Placeringen af flyderingene 4 bestemmer således lokaliseringen af skjulene 6, således at disse er fordelt jævnt over basinets overflade.FIG. 1 is a perspective view of a basin 2 in an aquaculture farm comprising float rings 4 in which are suspended cover 6 for parasite eaters in the form of enclosures 6 according to the invention. The basin 2 is supported by a side boundary 8 to which the float rings 4 are attached at the first anchor lines 10. Further, there are other positioning lines 12 between the float rings 4, whereby the spacing between the float rings 4 is maintained. Thus, the location of the float rings 4 determines the location of the sheds 6 so that they are evenly distributed over the surface of the basin.

I det efterfølgende skal termerne skjul, parasitæderskjul forståes som indeslutningen 6, og disse benævnelser vil blive benyttet i flæng.Hereafter, the terms hide, parasite hide will be understood as enclosure 6, and these terms will be used interchangeably.

Fig. 2 er et detail-perspektivbillede af en flydering 4 i hvilken er ophængt et skjul 6 for parasitædere i form af indeslutninger ifølge opfindelsen. Skjulet 6 er i den viste udførelsesform udformet som en kasseformet indeslutning 6 med en rekangulær grundform, omfattende en bund 14 (se fig. 5), to parallelle langsider 16, to gavle 18 og et saddeltag 20. Skjulet 6 er ophængt i fire ophængningsliner/wirer 22, der, som det tydeligere fremgår af fig. 3 og fig. 5, er løsbart fastgjort til fastgørelsesøjer 25 i gavlene 18 af den kasseformede indeslutning 6.FIG. 2 is a detail perspective view of a float 4 in which is suspended a cover 6 for parasite eaters in the form of enclosures according to the invention. The shed 6 is in the embodiment illustrated as a box-shaped enclosure 6 with a recangular base shape, comprising a base 14 (see Fig. 5), two parallel long sides 16, two gables 18 and a saddle roof 20. The shed 6 is suspended in four suspension lines / wires 22 which, as can be seen more clearly in FIG. 3 and FIG. 5, is detachably attached to attachment eyes 25 in the gables 18 of the box-shaped enclosure 6.

Som det fremgår affig. 2, men tydeligere affig. 3, fig. 5 og fig. 6, omfatter skjulet 6 et antal spalteformede åbninger i et niveau over bunden 14 af skjulet 6. De spalteformede åbninger omfatter en spalteformede åbning 24 i hver langside, samt en spalteformet, svagt V-formet åbning 26 i hver af gavlene 18.As the affidavit states. 2, but more clearly. 3, FIG. 5 and FIG. 6, the sheath 6 comprises a plurality of slit-shaped openings at a level above the bottom 14 of the shed 6. The slit-shaped openings comprise a slit-shaped opening 24 on each long side, and a slit-shaped, slightly V-shaped opening 26 in each of the gables 18.

Som det fremgår affig. 2, fig. 3, fig. 5 og fig. 6, har den kasseformede indeslutning 6, et rundtgående skydespjæld 28, der kan indtage en aktiv position, hvor dette dækker og blokerer de spalteformede åbninger 24, 26 i langsiderne 16 og gavlene 18, og en passiv position (jf. fig. 5), hvor den nedre kant 30 af skydespjældet 28, hviler imod udstående stopknaster 32 på ydersiden af skjulet 6 (jf. fig. 5), og hvor nævnte spaleformede åbninger er fri for passage af parasitædere, ud og ind i skjulet 6.As the affidavit states. 2, FIG. 3, FIG. 5 and FIG. 6, the box-shaped enclosure 6 has a circumferential slider 28 which can occupy an active position where it covers and blocks the slit-shaped openings 24, 26 in the long sides 16 and the gables 18, and a passive position (cf. Fig. 5). wherein the lower edge 30 of the slider 28 rests against protruding stop lugs 32 on the outside of the sheath 6 (cf. Fig. 5), and wherein said slot-shaped openings are free of passage of parasite eaters, out and into the sheath 6.

Som det endvidere fremgår af nævnte figurer, men tydeligst affig. 5 og fig. 6, har skydespjældet 28 midt for hver af gavlene 18, et udstående pladeformet parti 34, der via en til skydespjældet fastgjort første wire 36 og en til skydespjældet fastgjort anden wire 38, samles i et samlepunkt 40, der omfatter i det mindste enAs also shown in the figures, but most clearly affable. 5 and FIG. 6, the slider 28 in the middle of each of the gables 18 has a protruding plate-shaped portion 34 which, via a first wire 36 attached to the slider and a second wire 38 attached to the slider, is assembled at an assembly point 40 comprising at least one

DK 2017 00266 A1 samlering/sjækel eller lignende. Det skal anføres at den første og den anden wire 36, 38, kan være løsbart fastgjort til skydespjældets pladeformede parti 34.DK 2017 00266 A1 assembly / shackle or similar. It should be noted that the first and second wires 36, 38 may be releasably attached to the plate-shaped portion 34 of the damper.

Sam lepunktet 40, er løsbart forbundet med en tredje wire 42, der er ført opefter til er forbundet med en blok 44 med et sporskåret wirehjul 46, på midten af en i hovedsagen omvendt Il-formet bjælke 48, der er forankret på flyderingen 4, hvorfra den tredje wire 42 er forbundet til en første oplænder 50 med et hånddrevet spil 52, beregnet for op- og nedhejsning af skjulet imellem den i fig. 2 viste position, hængende i ophængningslinerne/wirerne 22, og en løftet position, hvor samlepunktet 40 befinder sig imellem vandoverfladen i dambruget og det sporskårne wirehjul 46.The assembly point 40 is releasably connected to a third wire 42 which is led upwardly connected to a block 44 with a groove wire wheel 46, in the middle of a substantially inverted Il-shaped beam 48 anchored on the float ring 4. from which the third wire 42 is connected to a first upright 50 with a hand-driven winch 52, intended for raising and lowering the cover between the one shown in FIG. 2, hanging in the suspension lines / wires 22, and a raised position, where the junction 40 is between the water surface of the pond and the track cut wire wheel 46.

Som det tydeligst fremgår affig. 3, 4 og 6, omfatter indeslutningen øvre stop 54, der er beregnet for modhold for den øvre kant 56 af skydespjældet 28. Disse øvre stop 54, er i den viste udførelsesform af indeslutningen 6, identiske med kroppene af fastgørelsesøjerne 25. De øvre stop 54 tjener som modhold for skydespjældet 28, når dette er hævet til dettes aktive position, og skjulet 6 ønskes hævet opefter imod vandspejlet i dambruget, ved hjælp af det hånddrevne spil 52, hvor indeslutningen 6 således bæres kontaktpunkterne imellem skydespjældets øvre kant 56 og de øvre stop 54 og i den første-, anden- og tredje wire 36, 38, 42.As most clearly stated, affig. 3, 4 and 6, the enclosure comprises upper stop 54 intended for abutment of the upper edge 56 of the slider 28. These upper stops 54, in the illustrated embodiment of the enclosure 6, are identical to the bodies of the attachment eyes 25. The upper stops 54 serves as a stop for the damper 28 when raised to its active position, and the cover 6 is desired to be raised upwardly against the water level in the pond use, by the hand operated winch 52, the enclosure 6 being thus carried the contact points between the upper edge 56 of the damper and the upper stop 54 and in the first, second and third wires 36, 38, 42.

Den første-, anden og tredje wire 36,38,42 tjener således to formål, det første til at hæve og sænke skydespjældet imellem den passive og den aktive position, og dels til at hæve og sænke skjulet imellem dettes nedsænkede position i dambruget, hængende i ophængningslinerne/wirerne 22, og til en position, hvor samlepunktet 40 er beliggende imellem vandoverfladen og det sporskårne wirehjul 46 i blokken 44, på den omvendt Il-formede bjælke 48 der er forankret til flyderingen 4.Thus, the first, second and third wires 36,38,42 serve two purposes, the first for raising and lowering the slider between the passive and the active position, and secondly for raising and lowering the cover between its submerged position in the pond, hanging in the suspension lines / wires 22, and to a position where the junction 40 is located between the water surface and the grooved wire wheel 46 of the block 44, on the inverted Il-shaped beam 48 anchored to the float ring 4.

Som det fremgår af fig. 5 og fig. 6, men tydeligst af fig. 7, er den første- og den anden wire 36, 38 ført i guiderør 58, forankret til gavlene 18 med afstandsbeslag 60, i den hensigt at beskytte sadeltaget 20 imod skader når skjulet 6 hales op og ned af flyderingen 4.As shown in FIG. 5 and FIG. 6, but most clearly of FIG. 7, the first and second wires 36, 38 are guided in guide tubes 58, anchored to the gables 18 with spacer brackets 60, for the purpose of protecting the saddle roof 20 from damage when the cover 6 is tilted up and down by the float 4.

Som det fremgår af fig. 2,3,5,6 og 7, omfatter sadeltaget 20 et udtag 61, dækket med et transparent pladestykke 62, dette tjener til at det bliver muligt at foretage visuel kontrol af det indre af indeslutningen/skjulet 6, herunder at kunne kontrollere den kunstige havbund, samt forekomsten af parasitædere i skjulet.As shown in FIG. 2,3,5,6 and 7, the saddle roof 20 comprises an outlet 61, covered with a transparent plate piece 62, which serves to enable visual inspection of the interior of the enclosure / cover 6, including being able to control the artificial seabed, as well as the presence of parasite eaters in the hide.

De skrånende tagflader på sadeltaget 20 tjener til at modvirke ansamling af fækalier fra de i dambruget værende laks eller ørreder, og imod ansamling af foderrester.The sloping roof surfaces of the saddle roof 20 serve to counteract the accumulation of fecal matter from the salmon or trout in the farm, and against the accumulation of feed residues.

Som det fremgår affig. 5 og 6, omfatter det udstående pladeformede parti 34 på skydespjældet 28, i den øvre imod gavlen 18 tilvendende ende 64, et bort fra gavlen skrånende parti 66, der afsluttes med et udtag 68 i det pladeformede parti 34, der samvirker med en horisontalt orienteret låseplade 70, der er lejret på de indvendige gavlsider 18. Låsepladen 70 udgøres afen ombukket endedel af et udkraget pladestykke 72, der rager ud igennem et dermed samvirkende udtag 73 i gavlene 18. Det udkragede pladestykke er fastgjort til gavlene 18 sammen med afstandsbeslagene 60. Som det yderligere fremgår er det udkragede pladestykke 72 forsynet med en trækring 74 der er tilsluttet en fjerde wire 76, der forbinder de udkragede pladestykker 72 ved hver af gavlene 18. Som det yderligere fremgår, af fig. 5,6 og 7, er den fjerde wire 76 ved midten tilsluttet en femte wire 78, der forløber opefter, igennem et hul 80 i sadeltagets kip 82, og videre opefter til blokken 44, til et andet sporskåret wirehjul 84, og videre herfra til en anden oplænder 86 der er forankret til flyderingen 4, hvor enden af den femte wire 78 er løsbart fastgjort.As the affidavit states. 5 and 6, the protruding plate-shaped portion 34 of the slider 28, at the upper end 64 facing the end of the gable 18, comprises a portion 66 away from the end of the gable, which terminates with an outlet 68 in the plate-shaped portion 34 cooperating with a horizontally oriented one. locking plate 70 mounted on the inner gable sides 18. The locking plate 70 is formed of a folded end portion of a projected plate piece 72 which protrudes through a cooperating outlet 73 in the gables 18. The projected plate piece is fixed to the gables 18 together with the spacers 60. As is further apparent, the projected plate piece 72 is provided with a pull ring 74 connected to a fourth wire 76 connecting the projected plate pieces 72 at each of the gables 18. As can be seen further, in FIG. 5.6 and 7, the fourth wire 76 is connected at the center to a fifth wire 78 extending upwardly, through a hole 80 in the saddle roof tilt 82, and further upward to the block 44, to a second groove wire wheel 84, and further thence to another upright 86 anchored to the float ring 4, the end of the fifth wire 78 being releasably attached.

Ved denne konstruktion opnås følgende. Skydespjældet 28 kan ved hjælp af det hånddrevne spil 52 hæves fra sin passive position, hvilende på de nedre stop 32 til den aktive position, hvor skydespjældet afspærrer åbningerne 24, 26 i indeslutningens sider. Under ophalingen af skydespjældet 28, vil det skrånende parti 66 gå i anlæg med låsepladen 70, hvis udkragede del 72 vil give efter indtil udtaget 68 nås, hvorefter låsepladen 70 forskyder sig selv ved fjederkraften i pladestykket 72, ind i udtaget 38, jf. fig. 6, hvorefter skydespjældet 28 er låst i den aktive position, hvor åbningerne 24, 26 til skjulet 6 er spærret af skydespjældet. Skydespjældet udløses ved at trække i den femte wire 78 ved den anden oplænder 86, samtidigt med at det hånddrevne spil 52 udløses. Herved trækkes den udkragede del 72 og dermed låsepladen 70 ud af udtaget 38, og skydespjældet 28 er nu frigjort, og kan sænkes til sin passive position hvilkende på den nedre stop 32.In this construction, the following is achieved. The slider 28 can be raised from its passive position by the hand operated winch 52, resting on the lower stops 32 to the active position where the slider blocks the openings 24, 26 in the sides of the enclosure. During the lifting of the slider 28, the sloping portion 66 will engage the locking plate 70, the projected portion 72 of which will yield until the recess 68 is reached, after which the locking plate 70 displaces itself by the spring force in the plate piece 72, into the recess 38, cf. . 6, after which the damper 28 is locked in the active position, where the openings 24, 26 of the cover 6 are blocked by the damper. The slider is triggered by pulling on the fifth wire 78 by the second upright 86, while triggering the hand-operated winch 52. Hereby, the projected portion 72 and thus the locking plate 70 is pulled out of the outlet 38, and the slider 28 is now released and can be lowered to its passive position resting on the lower stop 32.

Fordelen ved låsearrangementet 68,70, 72 for skydespjældet 28 er yderligere, at åbningerne til skjulet kan holdes lukkede ved transport af skjulet indeholdende parasitæderfisk, kunstig havbund og vand.The advantage of the locking arrangement 68,70, 72 for the slider 28 is further that the openings for the shed can be kept closed by transporting the shed containing parasitic fish, artificial seabed and water.

Som det yderligere fremgår affig. 3, 5 og 6, omfatter hver af langsiderne 16 en hulrække 88, der tjener til at afdræne skjulet for vand til hulrækkernes niveau over bunden af indeslutningen 6. Dette letter håndteringen af skjulet 6, idet vægten heraf reduceres betragteligt ved fjernelse af det vand der ellers ville befinde sig ovenover hulrækkerne 88.As it is further stated, affig. 3, 5 and 6, each of the long sides 16 includes a row of 88 which serves to drain the shed of water to the level of the shelves above the bottom of the enclosure 6. This facilitates the handling of the shed 6, the weight thereof being considerably reduced by removing the water which otherwise would be above the hollow rows 88.

Som det fremgår tydeligst af fig. 7 er sadeltaget 20 forankret til gavlene 18 af indeslutningen 6, idet afstandsbeslaget 60, nærmest sadeltagets kip 82 omfatter en stumpt opstående tap 90, der samvirker med udtag 92 i hver ende af sadeltagets kip 82, hvilke tappe 90 har en længde således at de rager et stykke op over sadeltagets kip 82. Tappene 90 omfatter et gennemgående udtag 94 for optagelse af en med tappen samvirkende låseanordning 96 der låser taget i den korrekt monterede position. Udtaget 94 er således placeret, at sadeltaget 20 i sin korrekt monterede position er presset an imod gavlene 18 og langsiderne 16, og holdes i denne position ved låseanordningerne 96. Sadeltaget 20 sidder således i spænd i sin korrekt monterede position på skjulet 6, hvilket medfører at søgangen omkring skjulet 6, ikke foranledige dunkende lyde, der kan skræmme parasitæderne bort fra skjulet.As can be seen most clearly in FIG. 7, the saddle roof 20 is anchored to the gables 18 of the enclosure 6, the spacer 60, close to the saddle roof tilt 82, includes a blunt upright pin 90 which cooperates with the outlet 92 at each end of the saddle roof tilt 82, which pins 90 have a length so that they protrude. The lugs 90 comprise a through-going outlet 94 for receiving a locking device 96 cooperating with the lug which locks the roof in the correctly mounted position. The recess 94 is positioned so that the saddle roof 20 in its correctly mounted position is pressed against the gables 18 and the long sides 16 and is held in this position by the locking means 96. The saddle roof 20 thus sits in tension in its correctly mounted position on the cover 6, which results in that the sea around the shed 6 does not cause throbbing sounds that can scare the parasites away from the shed.

Som det fremgår affig. 2, 3, 5 og 6, omfatter skjulet i den viste udførelsesform ben 98, der rager nedefter fra indeslutningens bund 14. Disse ben 98 tjener til at lette håndteringen af indeslutningen/skjulet 6, når dette skal transporteres på land, eksempelvis med en palleløfter eller gaffeltruck. Opfinderen har naturligvis erkendt, at der kan vælges andre egnede udførelsesformer af attributter, der rager nedad fra indeslutningens bund 14 for hensigtsmæssig transport med førnævnte transportmidler, end de her viste ben 98.As the affidavit states. 2, 3, 5 and 6, the shed in the illustrated embodiment comprises legs 98 projecting downwards from the bottom of the enclosure 14. These legs 98 serve to facilitate handling of the enclosure / shed 6 when it is to be transported on land, for example with a pallet truck. or forklift. The inventor has, of course, recognized that other suitable embodiments of attributes projecting downwardly from the bottom 14 of the enclosure for convenient transportation with the aforementioned means of transport may be selected from the legs 98 shown here.

Det skal anføres, at samtlige wirer det være sig ophængningsliner/wirer 22 den første og anden wire 36, 38, den tredje wire 42, den fjerde wire 76 og den femte wire 78, alle er således indrettet at disse kan afmonteres, således at skjulet/indeslutningen 6 kan frigøres helt fra flyderingen 4.It should be noted that all of the wires, whether they are suspension lines / wires 22, the first and second wires 36, 38, the third wire 42, the fourth wire 76 and the fifth wire 78, are all arranged so that they can be removed so that the cover / the containment 6 can be released completely from the float ring 4.

Fig. 4 er et detailbillede af samlepunktet 40, hvor den første wire 36 og den anden wire 38 samles i en første ring eller sjækkel 100, der er forbundet med en anden ring eller sjækkel 102, der er forbundet med den tredje wire 42. Det forudsættes at den første ring eller sjækkel 100 er tilpas stor til, at der også kan tilslutFIG. 4 is a detail view of the assembly point 40, wherein the first wire 36 and the second wire 38 are assembled in a first ring or socket 100 connected to a second ring or socket 102 connected to the third wire 42. It is assumed that the first ring or socket 100 is large enough for connection too

DK 2017 00266 A1 tes en yderligere ring eller sjækkel (ikke vist) der er forbundet til en ekstern kran, eksempelvis på et serviceskib, således at indeslutningen/skjulet 6, kan frigøres helt fra flyderingen, og bæres i den første ring 100, ved håndtering af skjulet/indeslutningen 6 imellem flyderingen 4 og et skibsdæk.An additional ring or shackle (not shown) connected to an external crane, for example on a service ship, such that the containment / cover 6 can be released completely from the float ring and carried in the first ring 100, when handled of the concealment / enclosure 6 between the float ring 4 and a ship deck.

Afslutningsvist skal det anføres, at opfinderen har erkendt, at indeslutningen 6, kan antage utallige udformninger en den der er vist i tegningen og beskrevet ovenfor, eksempelvis kunne skjulet udformes med en cirkulær grundform, men det ændrer ikke ved det opfinderiske aspekt i, at effektivisere bekæmpelsen af lakse10 lus i havdambrug ved etablering af skjul i form af afspærrelige indeslutninger, som det er beskrevet i det foranstående, således at der derved tilvejebringes et skjul for parasitæderne mens disse fordøjer lakselus, og endvidere, at parasitæderne ikke mistes, ved overpumpning/tømning af dambrugets netindeslutninger for laks, men at parasitæderne imens dette pågår, kan opbevares i lukkede skjul, således at de 15 ikke pumpes med over i transportskibets tanke, og dermed fjernes fra dambruget.In conclusion, it should be noted that the inventor has recognized that the enclosure 6 may take innumerable designs other than those shown in the drawing and described above, for example, the sheath could be designed with a circular basic shape, but it does not change the inventive aspect of making the the control of salmon10 lice in aquaculture by establishing shelters in the form of detachable inclusions, as described above, so as to provide a shelter for the parasitic species while digesting salmon lice, and furthermore that the parasiticities are not lost by overpumping / emptying of the fish farm's net inclusions for salmon, but while the parasites are in progress, they can be kept in closed hiding so that they are not pumped into the tanker of the transport vessel and thus removed from the fish farm.

Yderligere forekommer den fordel, at eftersom der ikke behøves at blive tilført så mange nye parasitædere udefra, at der derved undgås smittefaren ved tilførslen af nye parasitædere.Further, the advantage seems that since there is no need to feed so many new parasite eaters from outside, thereby avoiding the danger of infection when feeding new parasite eaters.
