Abstract

The invention discloses a fishing method using a mesopelagic trawl easily crossing an obstacle, and aims to solve the problems that in the mesopelagic trawling process, netting is easily torn, and a foot line is seriously abraded, so that mesopelagic fishing operation is seriously affected. During trawling, a towing warp is connected to a fishing boat, the whole trawl is casted into seawater, thetrawl goes down into the seawater, and the fishing boat drags the trawl to move forwards to catch fishes. When the trawl comes across an obstacle, rolling wheels connected to a crossing frame on the foot line of the trawl make contact with the obstacle first and roll over the obstacle, the crossing frame rotates to release impact energy, meanwhile, a withstanding plate moves towards an installation sleeve so as to drive a whole telescoping rod and the foot line to be bounced upwards, and the obstacle is crossed. After a certain time, the trawl is drawn in the fishing boat to obtain the fishes.

Description

technical field

[0001] The present invention relates to a fishing method, more particularly, it relates to a method of fishing with a mid-deep sea trawling net which facilitates crossing obstacles. Background technique

[0002] With the sharp decline of traditional continental shelf fishery resources, the development of deep-sea fishery resources has attracted the attention of many countries. Since 1985, my country's West African transoceanic pelagic fishery started, and the transoceanic pelagic fishery mainly develops shallow water fishery resources within 100m. After more than 30 years of development, the development of transoceanic traditional inshore fishery resources is facing a new bottleneck period, and relevant cooperative countries have successively strengthened their The protection of coastal and offshore resources and fishing regulations are becoming increasingly strict, so it is necessary to develop new fishing grounds and new resources in the deep sea. The exist...
