Description

Novel fish cage

The invention relates to the field of fisheries, in particular to a novel fish cage applied to marine culture. Prior art prior to the present invention

At present, most of the devices used for marine fish farming are floating row cages, which are simple in structure, not strong enough and easy to deform, and have poor wind and wave resistance. When encountering strong winds and lifting huge waves, they often impact damage to fish farming equipment and cause fish loss. Therefore, the farm can only be located on the nearshore water surface. However, most of the fish that are raised are deep-sea fish, such as stone spots and fine scales, which are not suitable for breeding on the upper water surface, and the mortality rate is high. There are also used waste tires, abandoned ships, etc. to settle on the bottom of the water, forming adult reefs to attract fish, but this practice causes seabed pollution. Moreover, the coastal water surface is often contaminated by various oils, so that the fish being kept are also polluted. In addition, in the existing fish farms, the weaker fish are often eaten by stronger fish to reduce the fish. The small fish debris used for feeding the fish will pollute the nearby seawater and the seabed, while using the nearshore when fishing. Trawling fish boats will also damage the fishery and reduce fry and fish. In order to solve the above problems, an object of the present invention is to provide a novel fish cage which is simple and sturdy in structure, convenient in assembly, adjustable in floating and sinking, suitable for different breeding heights and capable of reducing self-culture pollution.

Technical solution adopted by the invention

• The object of the present invention is achieved as follows: A novel fish cage characterized by comprising: a pipe frame assembled from a throat pipe through a throat pipe joint to form a body structure; a fish net or a soft cage, supported by the above-mentioned pipe frame support; Anti-shell type adhesive film, covering the surface of the above tube frame; - can pass the pressure confirmation The compressed air inlet that controls the lifting and lowering of the fish cage.

The fish net or the soft cage is provided with a shutter or a zippered entrance.

At least one side of the fish net or soft cage is a loose mesh surface.

Below the fish net or soft cage is a cloth pocket that can carry sand or shellfish.

The throat connector at the angle of the pipe rack is provided with a tapered protrusion for connecting the fish cage. The bottom of the pipe rack is provided with supporting legs.

The tube rack is provided with a flaky seaweed breeder.

The tube rack is provided with a shellfish culture device, and the pipe rack is provided with an anti-friction plastic roller.

Example

Figure 1 shows the most basic structure of the present invention - a single fish cage 1 comprising a pipe frame assembled from a throat pipe 18 through a throat pipe connector 16, a fish net 19 formed by the pipe frame support, and covered. An anti-shell adhesive film 17 and a compressed gas inlet 27 on the surface of the tube frame. The throat 18 is a tubular hollow body, and is assembled into a cubic structure through a three-way throat connector 16, and the surface thereof is covered with an anti-shell type adhesive film layer 17. When a certain number of shellfish are attached to the pipe rack, the anti-shell can be The paste-like film 17 is peeled off with the adhered shellfish, and a new anti-shell adhesive film 17 is replaced, so that the service life of the pipe rack is greatly extended. The pipe rack is provided with a compressed gas inlet 27, which can be connected with the helium gas pipe 11, and the compressed gas is introduced to control the fish cage lifting. Since the bottom surface of the pipe rack is provided with more pipes than the top surface, the bottom surface of the pipe rack can float to the water surface. The soft fish net 19 is enclosed in the pipe rack and can be easily disassembled. The fish net 19 can be stitched into a whole body (such as a six-sided cube) according to the shape of the skeleton, or at least one side thereof can be set as a loose-leaf mesh surface 41 (Fig. 3), and the fish net 19 can be provided with a lateral or vertical shutter 46 ( Can be fished), or zippered access 20 (feedable). The throat connector 16 on the pipe rack corner can also be provided with a tapered protrusion 15 for connecting the fish cage, which can conveniently combine the fish cage horizontally or vertically. Support feet are provided at the bottom of the pipe rack. Therefore, it will not destroy the seabed ecology, and can protect the seabed organisms such as shrimps, crabs, shellfish or seabed fish such as flounder, stone dog, etc., and are not afraid of the seabed gravel, and maintain the balance of the fish cage. Under the fishing net 19 with supporting feet, there is also a chemical fiber cloth bag 25 (Fig. 2) which can carry heavy objects such as sandstone or shellfish 26, which can absorb the debris and fish excrement, and avoid polluting seawater. Make the shellfish hypertrophy, and slow down the speed of the fish cage to prevent the fish from being injured and injured. Fish cages without support feet are suitable for placement on muddy seabeds.

Figure 2 shows a combination of several single fish cages 1 in Figure 1 combined to form a single fish cage 2 (can be set as a single layer or multiple layers as needed), each single fish cage 1 can be separately The word raises different seafood, which can be separated into water when harvested. Because there are not many suitable fish farming sites, combining fish cages can reduce the obstruction of the waterway and at the same time move the fishermen's work as a whole. The gap between the individual fish cages 1 allows small fish to intersperse among them to form an artificial reef.

Figure 3 shows the integrated fish cage 3. The original single fish cage hose 18 is directly extended through a plurality of four-way hose connectors 16 to form a whole body, and the entire fish cage can be raised by inflation. The fish net can be respectively attached to the pipe rack by a plurality of single fish nets 19 (fishing different fishes, and it is also convenient to separately wash and wash the fish nets), or a single-sided loose-leaf mesh surface 41 can be used to cover the outer surface of the pipe rack face by face, and There is no barrier inside the pipe rack, which makes the fish have a large movable space suitable for feeding large-sized fish such as blind Cao and squid. The loose-leaf mesh surface 41 can be closed, or has a shutter 46 or a zipper inlet and outlet 20, and the material can be made of metal mesh or chemical fiber mesh. The metal mesh can be used for breeding fish with strong mouth and like shellfish such as Sumei and Tsing Yi.

Figure 4 shows the built-in seaweed breeder fish cage 5. The seaweed spreader 50 is in the form of a sheet and includes a hook 51, a string 52, a support 53, and a breeding surface 54. The breeding surface 54 can be a film, a film, a metal or a non-metallic sheet. The breeding surface 54 is unfolded and the ends are passed through the support 53 (such as bamboo strips, strips or pipes), ropes 52 and hooks 51 are respectively fixed to the upper and lower throats 18 to form a plurality of rows of seaweed breeders 50. Because seaweed, small shellfish, and small crabs generally grow on rocks and masts below the horizontal line, many fish such as loach, squid, and aconite are made by eating shallow seaweed, small shellfish, etc., so they will be built in. The seaweed breeder fish cage 5 floats on the surface of the water, and the flaky seaweed breeder 50 will produce these surface creatures in large quantities to attract, catch and raise these fish.

Figure 5 shows a fish cage with built-in shellfish culture equipment. The shellfish culture apparatus includes a plurality of buoyancy basins 67 supported by a multi-layered hose bracket 68 and sand/mud 66 contained within the basin 67. Rotary anti-friction is mounted at a suitable location on the throat bracket 68. Full plastic roller 60. The built-in shellfish culture device fish cage 6 can breed shellfish, such as cockroaches (the cockroach can be placed near the estuary when it is small, and then moved to clean deep-water culture when grown up, so that the taste of the cockroach is better), abalone ( Like to grow on stone or stone seams, shrimp or sand shovel (with sand in buoyancy basin 67, then place the fish cage on the muddy sea floor), 蛤蚧 and other shellfish that grow in low mud (can be in buoyancy basin 67) Mix in sand and mud), sea fish such as flounder (completely sanded in buoyancy basin 67).

Figure 6 shows the outer shroud fish cage 7, the fairing 71 can be circular, elliptical, square, diamond, triangular, etc., in order to reduce the impact of lateral water flow and water resistance during lifting, the fairing 71 through rectification The cover bracket 96 (made of bamboo, metal strip or fiber glue) is fixed. At the same time, the soft cage 70 made of plastic film or chemical fiber cloth is connected to the fresh water through the water pipe connection, and can be used for brackish water cultivation to form an artificial estuary. The simulated artificial estuary fish cage is provided with a fish cage passage shutter 79, and the water delivery pipe 95 connects several fish cages through the fish cage passage shutter 79. Figure 7 shows another structural form of a simulated artificial estuary fish cage 8 with a passable bottom The planar tube holder 82, into which the compressed gas is lifted and lowered, is fixed to the planar tube holder 82 by a soft cage 81 supported by the fish cage bracket 96. Since there is no fairing, the soft cage 81 is shaped into various cushioning surfaces to reduce water flow impact, such as the rounded fish cage 86, the arched belt support foot fish cage 87, and the triangular fish cage 88 as shown in FIG. , trapezoidal fish cage 89 and so on. The bottom of the fish cage can be laid with chemical fiber cloth to support the sand stone, which can keep the fish cage vertical and can be used for fish to lay eggs. Because many marine fish need to spawn in the estuary, due to industrial development and dense population, many estuaries are also polluted, which has led to a sharp decline in the number of marine fish. However, reducing estuary pollution is not an easy task. Therefore, in the absence of rivers, digging wells or ponds to take water, or transporting non-polluting fresh water from the upper reaches of the river, injecting fish cages through the water pipes to provide a clean and safe spawning ground for the fish. , attract fish to come to lay eggs. Fish can be taken out and sold after spawning, while fish eggs hatch in fish cages. Due to the protection of the valve, the fry will not be eaten by big fish. When raised to the appropriate size, they can be transferred to deeper salt. Water fish cages can be reared in the ocean, and some can be returned to the ocean, increasing the number of marine fish and solving the problem of decreasing fish.

As shown in Figs. 10A and 10B, a shutter 111 for the diver to enter and exit may be provided on the fish net 19 or the soft cage 70. Preferably, the shutter 111 is provided on the loose mesh surface 41 for the diver to enter the fish cage or to feed the feed. A rectifying plate 112 is disposed below the fishing net 19 or the soft cage 70. The rectifying plate 112 is fixed to the pipe rack to surround the area below the fishing net 19 or the soft cage 70, so that the fish enters the area enclosed by the rectifying plate 112 when the water flow is rushing. Avoid inside. As shown in FIG. 10C, a water outlet 113 is provided at a place where the center of the cloth net 25 at the bottom of the fishing net 19 or the soft cage 70 is depressed. The water outlet 113 is a sleeve made of plastic, metal or ceramic, and the sleeve hole cover is made of fiber cloth. Or silk, forming a cloth filter outlet.

The farmer can determine the scale of production and cultivation according to the topography, water flow and funds, as shown in Figure 9. The various fish cages 1, 2, 3, 6, and 8 are settled on the bottom of the water by the heavy object/anchor 12, and the buoy/compressed air port 10 is connected through the anchor rope/intake pipe 11 on the pipe rack, and the fish cage is floated when the compressed air is input. When the water surface is taken, it can be pulled by the fishing boat or the tugboat 13. The artificial estuary fish cages 7 and 8 provide fresh water through the fresh water pumping/water supply pump 9, fresh water/feed conveying pipe 14, etc., and the built-in seaweed culture fish cage 5 semi-floating sea surface , forming a marine farm that attracts fish to come and grow. In the event of a typhoon or red tide, the fish cage can be towed to the deep water. When the fish or shellfish are grown to the right size, they can be towed to the shallow water.
