Description
Technical Field
The invention relates to the technical field of fishing nets, in particular to a self-contraction novel aquatic product fishing net.
Background
Fishing nets are indispensable fishing tools for fishery production, and coastal fishermen catch at sea by using simple net tools for the first time. In the fishing process, the trawl is placed on the water surface, and then the trawl is pulled by two pull ropes through manpower to surround the water surface, so that the fishes in the water surface can be fished.
The traditional fishing mode is to pull the fishing net manually to collect the net, the situation that fishes can enter the fishing net can be determined difficultly in the net collecting process, and generally the fishes depend on the fishing experience, so that empty nets can be collected sometimes; in addition, the labor intensity of manual net collecting operation is high, when the trawl is pulled by the pulling ropes, each pulling rope needs to be pulled by multiple persons, the net collecting intensity is high, the pulling range and distance of the fishing net in the net collecting process are far, the fish is easy to be frightened to escape, the fishing rate is high, the fishing efficiency is low, the damage to the fish body is large when the net is collected by a large margin, and the survival rate is extremely low after the fish catches out of the water surface, so that the commodity value of the fish is reduced, and the economic benefit of a fisher is damaged.
Therefore, a self-contraction type novel aquatic fishing net is provided to effectively solve the problems in the prior art.
