Abstract
The invention discloses a shelter and a method for mixed culture of octopus ocellatus and sea cucumbers. The shelter mainly consists of a skeleton and a polyethylene net attached to the skeleton, and the skeleton and the polyethylene net can be folded to be stored. The mixed culture method mainly comprises manufacturing of a shelter, layout of the shelter in a sea cucumber culture pond, elimination of harmful organisms in the pond, proper throwing opportunity of young octopus ocellatus and proper throwing density. The characteristic that the octopus ocellatus and the sea cucumbers do not eat each other and do not interfere with each other is utilized, and octopus ocellatus reefs can be used as shelters for young octopus ocellatus and adult octopus ocellatus; according to the relationship of a food chain in the pond, the advantage that rich copepoda and small shrimp and crabs in the sea cucumber culture pond can be used as baits of octopus ocellatus in different stages is utilized, so that the growth speed of octopus ocellatus is high, the survival rate is high, and the economic benefit of the sea cucumber culture pond in unit area is improved.
Description
Technical field
The invention belongs to mariculture technology field, especially a kind of short octopus and sea cucumber mixed cultivation method.
Background technology
Current holothruian cultures are like a raging fire, and occurred the technology that sea cucumber and fish, shrimp, crab, abalone, sea urchin are raised together with, but rarely have the report that sea cucumber and short octopus are raised together with.
Short octopus (
octopus ocellatusgray, 1849) belong to mollusk Cephalopoda (Cephalopoda), Octopodida (Octopoda), octopus section (Octopodidae), octopus belongs to (Octopus), is that in China's north Coast octopus class, most important economy one of is planted.
Short octopus cultivates new varieties as the north, and its artificial breeding, indoor pond and outdoor earth pond cultural technique are all ripe, and with application of putting into production.But some biological propertyes that short octopus self is intrinsic, make the unit are cultured output of short octopus not high, the output value of unit are is lower.In the case, the present invention aims to provide the technological means that a kind of science improves the unit are output value, by carrying out layout to outdoor breeding pond, short octopus and sea cucumber is utilized not to ingest mutually, and sea cucumber reefs can as the short octopus young and adulthood veil, and in holothurian pond, abundant sufficient class and the little Shrimp waste of scratching can as features such as the bait of short octopus juvenile stage and adulthood to realize the mixed breed of short octopus and sea cucumber.This technology to improving the economic benefit in unit are pond, there is positive effect.
Summary of the invention
The object of the present invention is to provide the veil jointly used when a kind of short octopus and sea cucumber mixed breed, another object is to utilize this veil to carry out the method for short octopus and sea cucumber mixed breed.
The present invention's first object is realized by following scheme: the veil jointly used when this short octopus and sea cucumber mixed breed is made up of skeleton and attached polythene net thereon, described skeleton comprises the first isosceles triangle 1, second isosceles triangle 2 identical with the first isosceles triangle 1 shape, connect the back timber 3 of the first isosceles triangle and the second isosceles triangle drift angle, connect the left bottom girder 4 at the first isosceles triangle and the left base angle of the second isosceles triangle, connect the right bottom girder 5 at the first isosceles triangle and the right base angle of the second isosceles triangle, along the first column 7 that the first isosceles triangle drift angle bisector extends, along the second column 8 that the second isosceles triangle drift angle bisector extends, connect the central sill 6 of the first column and the second column elongated end, 3 planes that back timber 3, left bottom girder 4, right bottom girder 5 combination of two are formed adhere to polythene net, 2 planes that central sill 6 and left bottom girder 4 and central sill 6 and right bottom girder 5 are formed adhere to polythene net./ 2nd places that first isosceles triangle 1 and the drift angle place of the second isosceles triangle 2, two base angles place all arrange the base of movable joint and the first isosceles triangle 1 and the second isosceles triangle 2 all arrange movable joint, are convenient to veil stored collapsed.
Preferred version is the drift angle of described the first isosceles triangle 1 is 30 ° ~ 50 °, and height is 80 cm ~ 100cm; Length 80 cm ~ 120 cm of described back timber 3, left bottom girder 4, right bottom girder 5 and central sill 6; The first described column 7 and the height of the second column 8 are 60 cm ~ 80cm.
The mesh number of described polythene net is preferably 10 ~ 20 orders.
The present invention's second object is realized by following scheme: utilize a kind of short octopus and sea cucumber mixed breed veil to carry out the method for short octopus and sea cucumber mixed breed, comprise: utilize coastal outdoor holothurian cultivation pond as polycultured ponds, the depth of water is 1.5 ~ 2.0 m; The harmful organisms of the short octopus young such as the larger fish in removing pond and crab class; At the bottom of culturing pool, evenly arrange veil, veil is spacing 2.0 ~ 2.5m in length and breadth; Hatch the short octopus of emerging to render in pond after indoor fortification in 1-2 days, throwing in density is 10-20/veil again.
The veil structure of a kind of short octopus of the present invention and sea cucumber mixed breed is simple, draw materials conveniently, can be short octopus and sea cucumber provides good habitat.Utilize short octopus and sea cucumber not to ingest mutually, non-interfering feature and utilize this veil to carry out short octopus as the artificial reef body of short octopus and sea cucumber mixed cultivation method simple and be easy to management; Simultaneously according to food chain relation in pond, abundantly in holothurian cultivation pond scratch sufficient class and little Shrimp waste has the bait that can be used as short octopus different phase, reduce aquaculture cost.Thus making short octopus fast growth, survival rate is high, holothurian cultivation pond unit are good in economic efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of veil skeleton of the present invention.
Fig. 2 is the structural representation of veil of the present invention.
Fig. 3 is the layout schematic diagram of Fig. 2 at cultivating pool.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
Embodiment 1, with reference to accompanying drawing 1,2.With diameter for 5mm fine steel rib is bent into the skeleton shown in Fig. 1, spray one deck plastics afterwards, wherein the drift angle of the first isosceles triangle 1 is 40 °, and height is 90cm; Length 110 cm of described back timber 3, left bottom girder 4, right bottom girder 5 and central sill 6; The first described column 7 and the height of the second column 8 are 70cm, mesh number is in 3 planes that 15 object polythene nets are coated on back timber 3, left bottom girder 4, right bottom girder 5 combination of two are formed, and is also coated in 2 planes that central sill 6 and left bottom girder 4 and central sill 6 and right bottom girder 5 form.
