Seine catch device and method of use

Abstract

The invention provides a purse seine fishing device and a use method, which belong to the technical field of purse seine fishing. The invention includes an annular floating body, a connecting plate, a net cylinder, a net cylinder cover, a screening mechanism and a feeding machine. The annular floating body is coaxially provided with round holes, and the bottom of the annular floating body is fixedly connected with an anchor through the first steel wire rope, and the connecting plate is horizontally fixed on the Directly above the annular floating body, a fishing chamber is provided in the net cylinder, and a fish inlet is provided at the upper end of the net cylinder, and the fish inlet communicates with the fishing chamber, and the net cylinder is arranged directly below the annular floating body through the first lifting mechanism. The first lifting mechanism can drive the net cylinder to move up and down, and the net cylinder cover is arranged between the annular floating body and the net cylinder through the second lifting mechanism, and the second lifting mechanism can drive the net cylinder cover to move up and down along the axial direction of the net cylinder, and the screening mechanism Smaller fish can be driven out of the fishing cavity, and the feeder can put bait into the round hole. The invention can control the time and quantity of the purse seine to catch, guarantee the freshness of the fish, and improve the fishing quality.

Description

technical field [0001] The invention belongs to the technical field of purse seine fishing, and relates to a purse seine fishing device and a use method. Background technique [0002] The seine breeding project refers to the use of nets, piles, floating balls (floating ropes, floating frames, suspension cables) and other engineering facilities to enclose a certain scale of waters in oceans, lakes, reservoirs or river waters. The selection has important economic value. It is an ecosystem-based aquaculture model to stock fish and implement controlled feed feeding. [0003] Due to the large space, natural environment and high quality of aquaculture products, seine aquaculture has gradually become a new model and main force of marine high-end aquaculture. [0004] However, an important problem facing seine farming is how to catch. The traditional trawling method has a great disturbance to the fish population. If it is not all at one time, this method is not accepted by the bre...

AI Technical Summary

Problems solved by technology

The traditional trawling method has a great disturbance to the fish population. If it is not all at one time, this method is not accepted by the breeding enterprises.

However, the use of gillnets, cages, etc., cannot control the time and quantity of the catch, and cannot realize the perennial supply and order-based catch requirements of the purse seine culture. request for arrest
