Marine fishing gear special for catching penaeus japonicus

Abstract

The marine fishing gear comprises a guide net and a plurality of main nets, a square support is arranged on the sides, close to the guide net, of the main nets, a plurality of net rings are arranged in the main nets, closing-in nets are arranged on the net rings, a fish separating slope net is arranged between the square support and the net rings, a fish inlet is formed between the main nets and the guide net, and a fish outlet is formed in the side, close to the guide net, of the main nets. And grabbing anchors are arranged at the ends, away from the square support, of the main net and the guide net, take-up assemblies are arranged in the grabbing anchors, piston power generation assemblies are arranged at the tops of the grabbing anchors, and monitoring cameras are arranged in the main net and the guide net. According to the device, the net cage can be conveniently opened, fishes and shrimps can conveniently enter the net cage, the fishes and the shrimps can be conveniently isolated, loss is avoided, juvenile fishes can conveniently escape, the purpose of protecting the juvenile fishes is achieved, meanwhile, the fluorescent trapping mode is more durable and stable, the device further has the efficient power generation function, lasting work is facilitated, and effective net drawing is facilitated.

Description

technical field [0001] The invention relates to the technical field of marine fishing, and more specifically relates to a marine fishing gear specially used for catching prawns. Background technique [0002] In marine fishing, the appropriate marine fishing gear is generally selected according to the seafood caught. In the fishing of Penaeus japonicus, fishing nets are mainly used for fishing, and traditional fishing nets have many defects when they are used: [0003] 1. Fishing net cages are easy to dump and pile up on the bottom of the sea, causing the fish and shrimp net inlets to not open normally, which is not conducive to the entry of fish and shrimp and the loading of fish and shrimp; [0004] 2. Traditional fishing cages lack measures to actively attract fish and shrimp, and most of them use food trapping, and food trapping is poor in persistence, and the trapping effect will deteriorate after being eaten by fish and shrimp; [0005] 3. It is impossible to distingui...

AI Technical Summary

Problems solved by technology

[0003] 1. Fishing net cages are easy to dump and pile up on the bottom of the sea, causing the fish and shrimp net inlets to not open normally, which is not conducive to the entry of fish and shrimp and the loading of fish and shrimp;

[0004] 2. Traditional fishing cages lack measures to actively attract fish and shrimp, and most of them use food trapping, and food trapping is poor in persistence, and the trapping effect will deteriorate after being eaten by fish and shrimp;

[0005] 3. It is impossible to distinguish and load fish and shrimp, and mixing fish and shrimp together will easily affect the quality;

[0006] 4. The fishing net cages on the bottom of the sea cannot allow the staff to accurately judge the situation of fish and shrimp entering. If there are not many fish and shrimp entering and the fishing net cages are put away, it will be more troublesome, time-consuming and laborious, and the benefits cannot be maximized.
