Description

technical field

[0001] The invention belongs to the technical field of fishery fishing, and in particular relates to an instant fishing device for lifting a net in a fish pond. Background technique

[0002] When fishing for finished fish in large-scale fish ponds, the staff drives the boat and spreads the bait to induce the fish to gather, and then lowers the fishing net to catch; in the actual operation process, the staff completes the casting, collecting and pulling the net to the shore, and the manual High physical exertion, low work efficiency, and a small amount of finished fish caught in a single time, which cannot quickly meet the demand for sales; after catching, the finished fish and juvenile fish are mixed together, and the juvenile fish are greatly damaged by the fishing net and then put into the fish pond. , and manual sorting of juvenile fish consumes a lot of energy. Contents of the invention

[0003] The purpose of the present invention is to address the de...
