Technical Field

The invention relates to an aquatic product fishing tool, in particular to an underwater non-winding degradable artificial fish collecting device.

Background

In the 50 s of the 20 th century, fishermen found tuna colonies near floating objects on the ocean surface, such as logs, large mammal carcasses, human waste, and the like, during purse seine fishing operations. Fishermen use this behavioral characteristic to invent and lay artificial Fish gathering Devices (FADs) to capture their nearby Fish population. The device is used for fishing, so that the fish searching time is saved, the net empty rate is reduced, and the fishing efficiency and the fishing yield are improved. With the great release of FAD in recent years, marine organisms such as scarab, shark and the like die, and plastic garbage is mistakenly eaten by ghost fishing and marine organisms to harm marine ecological environment. There is no unified policy for managing FAD currently, which results in that FAD manufactured and delivered by one ship will be salvaged or damaged by other ships and lost, increasing the operation cost.

The existing FAD structure mainly comprises four parts, namely a BIO covering object, a raft body, a positioning buoy and an underwater suspended matter, wherein the log, a bamboo raft, an oil drum and the like are wrapped by waste netting to serve as a floating object on water, the raft body floats on the water surface, the underwater part adopts a net structure, meshes are large (larger than 7mm), or ropes are used for replacing the net structure, and all the parts are connected by waste synthetic fiber nets or ropes. The manufacturing materials are from waste netting, floats, canvas and the like on the tuna purse seine.

The main body of the FAD used at the present stage is mostly made of large-mesh waste netting on a purse seine, the netting is made of artificial synthetic fibers, and the netting is high in strength, strong in aging resistance and difficult to degrade. The raft body of the FAD thrown at sea is easy to be found when floating on water, so that the FAD is often fished or damaged by other ships and lost, and simultaneously, the phenomena that marine organisms such as scarves, sharks and the like are killed, and the plastic garbage is mistakenly eaten by the ghost fishes, the marine organisms and the like which damage the marine ecological environment occur occasionally.

Disclosure of Invention

The invention aims to provide the underwater non-winding degradable artificial fish gathering device according to the defects of the prior art, the main body structure is made of non-winding degradable materials, the manufacturing cost is reduced, the quantity of artificial garbage entering the sea is reduced, and the risk of damaging the marine ecological environment is reduced.

The purpose of the invention is realized by the following technical scheme:

an underwater non-winding degradable artificial fish gathering device, comprising:

the hard frame raft body is arranged below the water surface, and a covering is paved on the upper surface of the hard frame raft body;

at least three floaters which are respectively connected with the edge of the hard frame raft body through degradable ropes;

the positioning buoy is connected with the hard frame raft body through a degradable rope;

the tree-shaped underwater suspended matter comprises a main line rope and branch lines connected to the side face of the main line rope; the top end of the main line rope is connected with the hard frame raft body, and the bottom end of the main line rope is connected with a sinker; the tail end of the branch rope is connected with a lure; a plurality of palm leaves are arranged on the main line rope and the branch line rope; the main line rope and the branch line rope are made of degradable materials.

A further development of the invention is that the positioning buoy and the floats are connected together by non-degradable lines.

The invention has the further improvement that a sinker is arranged below the center of the hard frame raft body.

A further development of the invention consists in that, in tree-like underwater suspensions, the main line rope length is 8 to 12 m; the length of the branch rope is 0.6-1.4 m; the setting interval of the branch ropes on the main rope is 2 m.

The invention is further improved in that the number of the tree-shaped underwater suspensions is equal to the number of the floaters; the junction of the main line rope of the tree-shaped underwater suspended matter and the hard frame raft body is positioned right below the floater.

The invention is further improved in that a solar cell panel, a satellite positioning device and a communication device are arranged in the positioning buoy.

A further development of the invention is that the petioles of the palm leaves are inserted in the gaps between the strands of the main and branch lines.

The invention has the further improvement that the hard frame raft body is made of bamboo wood, and the covering is canvas made of plant fibers.

The invention has the advantages that: the hard frame raft body, the tree-shaped underwater suspended matters and other main components are arranged underwater, so that excessive exposure on the sea surface can be avoided, the risks of loss and theft are reduced, and the stealing of other fishing boats can be avoided; arborescent suspended solid and stereoplasm frame raft body all adopt natural degradable material to make under water, will degrade gradually along with the time lapse of soaking in the ocean, only have float and buoy drift on the ocean surface after the structure disintegrates, and the accessible location is retrieved and is used once more, greatly reduced harm marine ecological environment's risk, practice thrift the cost of manufacture.
