Description

Fishery culture platform for quick batch fishing in ocean

Technical Field

The invention relates to the technical field of cage fishing, in particular to a fishery breeding platform for quick and batch marine fishing.

Background

The net cage is widely applied as a novel efficient aquaculture device, but the general net cage is single in structure and simple in function, and does not have the function of autonomous fishing.

Some aquaculture net cages with fish catching function exist in the market at present, for example, a hierarchical fish catching net cage with the Chinese patent publication No. CN209436061U comprises a catching net cage body, a first net plate and a second net plate, wherein the first net plate and the second net plate are arranged in the catching net cage body, and the catching net cage body is of a rectangular box body structure without an upper surface. By arranging a plurality of net plates, fishes are caught in batches.

However, like the lifting type otter board fishing in the above application, when the otter board is lifted to the top to harvest the fish, the otter board is required to descend and reset, a large number of small fishes are arranged in the net cage, and when the otter board descends, the fishes are frightened to drill downwards, and because the holes of the otter board are not very large, the otter board descends to easily extrude the fishes, so that unnecessary loss is caused.
