Definitions

  • the present invention generally relates to aquaculture pens or fish-farming nets that are used to contain and raise freshwater and/or saltwater aquatic life like fish.
  • the aquaculture pen provides a controlled environment for raising the aquatic life and protects the aquatic life against predators, e.g. sharks.
  • the term "net” must be interpreted broadly and covers any flexible meshed structure as well as rigid meshed structures, sometimes called cages.
  • Aquaculture pens typically consist of a meshed net connected to a floating support, e.g. a raft or pontoon.
  • the meshed net is made out of a polymer such as polyethylene, polyester, polyamide, nylon, etc. or out of chain like metal wires such as stainless steel wires, galvanized steel wires or coated steel wires.
  • the dimensions and weight of an agriculture pen are considerable. Typical dimensions are in the range of 30 m width x 30 m length x 15 m depth.
  • PCT Patent Application WO 03/091584 entitled “Suspension Hook and Spiral- Shaped Net Joiner” discloses an aquaculture net, 42 in Fig. 17, that is connected to a floating support, 50 in Fig. 17, through a number of rigid hooks, 20 in Fig. 17.
  • the rigid hooks are pivotable in order to enable the meshed net to move under the influence of currents.
  • the pivotable hook is made out of steel, optionally galvanised, coated or stainless steel.
  • Fig. 1 shows an aquaculture pen whose net 50 is connected at regular distances along its circumference to a rail 56 mounted on a floating pontoon 12.
  • the connection between net and rail is realized through ties, e.g. short lengths of rope or off-the-shelve plastic rib lock ties as . -
  • Fig. 6.3 is a rather radical, complex and expensive solution.
  • An alternative for the sea station drifter is a rigid seabed bottom cage, also shown in Fig. 6.3, which is a submerged fish cage of very robust design.
  • the rigid seabed bottom cage however is an expensive solution that is not recommended when the height of waves is expected to exceed 15 metres.
  • an aquaculture pen for containing and raising aquatic life in water comprising:
  • the floating element e.g. the raft, pontoon, sidewalk, etc. is following the movements of the water surface. These movements can be very intense due to tidings, weather conditions, etc.
  • the net on the other hand, due to its size and weight, does not follow the movements of the water.
  • the use of an energy absorbing material for at least a portion of the juncture between the floating element and the net will release the net of the forces resulting from the movements of the water surface relative to the net. As a consequence, the net shall not be ruptured and no openings will be created in the net near the water surface.
  • the entire juncture can be made out of the energy absorbing material or alternatively, only a portion such as a band or strip may be made out of the energy absorbing material, whereas remaining parts of the juncture may constitute rigid portions.
  • An additional advantage of the energy absorbing material is that fewer junctures have to be provided than was the case for rigid, metallic junctures. Up to 5 times fewer junctures have to be deployed along the circumference of the net thanks to the current invention.
  • An optional feature of the aquaculture pen according to the present invention is that the energy absorbing material is water resistant, as specified by claim 2. . .
  • the materials used for such juncture are water resistant.
  • the energy absorbing material however need not be water resistant.
  • a further optional feature of the aquaculture pen according to the present invention is that the energy absorbing material is corrosion resistant, as specified by claim 3.
  • the materials used for the juncture are preferably corrosion resistant, or made corrosion resistant e.g. through coating.
  • the energy absorbing material is rubber.
  • the energy absorbing material is reinforced rubber.
  • the forces on the juncture resulting from relative movements between the floating structure and the net may be high, requiring a reinforced energy absorbing material such as reinforced rubber for the juncture or portion thereof.
  • the means for connecting that form part of the aquaculture pen according to the present invention comprise a cut rubber hose.
  • the juncture or a portion thereof may for instance be constituted by a rubber hose such as the Goodyear Type 10 rubber hose that has an internal diameter of 6" and an external diameter of 170 mm.
  • This rubber hose is reinforced with 8 cloths, each ring having a width of 20 to 25 mm.
  • the rubber hose has a rupture load capacity of 800 to 1000 kg per ring. Any alternative material that can be employed as shock or energy absorber and that has a 1000 kg tear load can be used.
  • a further option of the aquaculture pen according to the present invention is that the means for connecting comprise a juncture for each meter of circumference of the meshed net, as specified by claim 7.
  • the rigid prior art junctures such as metal hooks or ropes typically are employed every 20 or 30 cm
  • the energy absorbing junctures according to the present invention can be employed every meter, reducing the number of junctures needed for instance from 320 to 96 for a circular net with a 30 m diameter.

  • Each juncture consists of a rope 104 connected to the raft 102 and a reinforced rubber portion 103.
  • the rubber portion 103 is cut from a Goodyear Type 10 reinforced rubber hose that has 6" internal diameter and 170 mm external diameter. It is reinforced with 8 cloths, each ring having a width of 20 to 25 mm. Thanks to the rubber portion, stress applied on the upper part of the fishfarming net 101 , i.e. the first metres of the net below the water surface, is avoided.
  • the rubber joint 103 absorbs the shocks that result from relative movement between the raft 102 following the water surface movements and the fish-farming net 101 that . _
  • the rubber joint 103 helps the squares or chains in the mesh 101 around the rubber joint 103 to withstand the weight of the fish-farming net 101.
  • Fig. 2 shows a circular aquaculture pen wherein a fish-farming net 201 is connected to a circular pontoon 202 through a number of junctures 203, only a few of which are shown in Fig. 2.
  • the circular net 201 is supposed to have a diameter of 30 m, hence a perimeter of 96 meter.
  • the junctures 23 are deployed every meter, thus requiring 96 junctures.
  • the entire juncture 23 is made out of reinforced rubber and consists of a cut Goodyear Type 10 hose with 4" internal diameter and 116 mm external diameter. It is reinforced with 6 clothes, each ring having a rupture load of 750 kg. Again, the junctures in Fig.
  • the rubber juncture 203 not only absorbs energy resulting from the relative movements between net and pontoon, but also can withstand seawater conditions, and it is corrosion resistant.
  • the reinforced rubber hose may be employed in combination with ropes or other materials in order to constitute junctures for connecting fish-farming nets to circular pontoons or rafts.
  • any alternative energy absorbing material could serve to implement the current invention.
  • materials from the elastomer family like natural rubber, polybutadiene, neoprene, silicone, viton, polyurethane rubber, and others could be used for the junction or portion of the junction between the net and the floating element whereto the net is attached.
  • the rubber hose which constitutes the juncture or part of the juncture drawn in Fig. 1 and Fig. 2 is closed through employment of nuts and bolts.
  • a closed ring rubber juncture can be used to constitute the juncture or a portion of the juncture according to the current invention, thus avoiding the use of nuts and bolts.
  • Another remark is that the dimensions and weight of the net, the distances between two neighbouring junctures are only given by example. It will be appreciated by the person skilled in the art that the advantages related to the current invention are also achieved or partially achieved when the net has different dimensions, when the junctures are not deployed equidistantly along the circumference or not every meter.
  • the aquaculture net that was supposed to be made out of galvanized steel wire in the above embodiments, alternatively can be made out of steel wire with a corrosion resistant coating or with an antifouling coating.

Abstract

Cette invention porte sur un enclos d'aquaculture pour contenir et cultiver une vie aquatique dans de l'eau, qui comporte un filet à mailles (101) et des moyens (103, 104) pour raccorder ce filet à mailles (101) près de la surface de l'eau à un élément flottant (102), par exemple un radeau ou un ponton. Les moyens (103, 104) de raccordement consistent au moins partiellement en un matériau à absorption d'énergie, comme par exemple du caoutchouc renforcé.
