Bottom trawl device for shallow sea fishing

Abstract

The invention discloses a bottom trawl device for shallow sea fishing, aims to solve the problems that large-scale fish schools can be expelled by noise of ships and parts of fish schools on a seabedroute can be scared by a bottom trawl close to the route, and provides the following scheme. The bottom trawl device comprises a mounting frame, and two mounting rods are fixedly connected to the outer wall of the bottom of the mounting frame; one same induction cage is fixedly connected to the outer walls of the opposite sides of the two mounting rods, a fixing frame is fixedly connected to the inner wall of the induction cage, an impeller is connected to the outer wall of one side of the fixing frame through a bearing, and an illuminating lamp is fixedly connected to the outer wall of the other side of the fixing frame; and an annular storage bin is arranged at one side of the inner wall of the induction cage. According to the bottom trawl device, trapping baits are scattered into a fishing net along a linear path from leakage holes in the outer wall of one side of an annular storage bin, in cooperation with light beam irradiation of an irradiation lamp, so that the trapping baits sprayed backwards are more conspicuous, more fish schools are introduced, and the fishing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of marine fishery fishing tools, in particular to a bottom trawling device for shallow sea fishing. Background technique [0002] At present, trawling is a fishing operation method in which fishing boats tow bag-shaped nets to force fishing objects into the nets. It can actively and flexibly drag fish schools. Primarily used in marine applications, there are also applications in inland waters. Fishing targets are mainly bottom and near-bottom fish, shrimp and molluscs, such as cod, herring, hairtail, horse-faced puffer, large yellow croaker, small yellow croaker, cuttlefish, calamari, flounder, shrimp, crab and domesticated fish in the ocean. Qinghai Lake naked carp, sword anchovy, whitebait, white shrimp, etc. in land waters. Trawling is one of the most important fishing methods in modern times. [0003] The existing bottom trawling device for shallow sea fishing has the following problems: the bottom t...

Problems solved by technology

[0003] The existing bottom trawling device for shallow sea fishing has the following problems: the bottom trawling is driven by the ship from the shallow seabed, not only the noise of the ship itself will drive away large-scale fish, but the bottom trawling following the route will scare the seabed route Therefore, there is an urgent need for a bottom trawling device for shallow sea fishing to solve the above problems
