Abstract

The invention relates to a marine ranch selective automatic fishing device and process, and belongs to the field of marine fishery resource development fishing. The marine ranch selective automatic fishing device comprises a bait pool and a fishing net rack, the bottom of the bait pool is provided with a feeding hole, the top surface of the fishing net rack is fixedly connected with the bottom surface of the bait pool, and grading net rack grooves are formed in four side surfaces of the fishing net rack; a plurality of mutually independent buoys capable of floating in the bait pool are arranged in the bait pool, each buoy is connected with a connecting rod, the connecting rods are arranged in the grading net rack grooves, and detachable grading net racks are arranged on the connecting rods; the connecting rods are arranged in the grading net rack grooves and drives the grading net racks to ascend and descend along with floating and sinking of the buoys. According to the marine ranch selective automatic fishing device and process, by throwing bait that planned catch fishes like to eat, fish schools are attracted to gather the bait, and classified catching of fish varieties is achieved; by selecting a grading net with proper mesh specification, young fish schools with the mesh specification smaller than that of the grading net are filtered out, the fishes which can be caught and have the mesh specification larger than that of the grading net are blocked, and fish body grading catching is achieved.

Description

technical field [0001] The invention relates to a selective automatic fishing device and a fishing process for marine pastures. It is a device for gathering fish shoals in marine pastures by throwing bait and selectively catching marine fishery resources in isolation, which belongs to the field of marine fishery resources development and fishing. Background technique [0002] Marine ranching is a new type of marine fishery production model based on natural productivity, using modern engineering technology and management models, through artificial proliferation and habitat restoration, and constructed in suitable sea areas with the functions of environmental protection, resource conservation and sustainable output of fishery resources. [0003] Marine ranching has been valued and applied by more and more countries. my country has approved the construction of 5 batches of 110 national-level marine ranching demonstration areas, with a total sea area of ​​200,000 hectares. The p...
