Problems solved by technology

[0003] At present, wheel-fishing and multi-species polyculture are important measures for high-yield and high-efficiency ponds. However, both of these two farming models are facing a problem—big fish and small fish compete for food, and small fish cannot grab feed. affect growth rate

Abstract

The invention relates to an isolation feeding device for breeding fishes. The isolation feeding device for breeding fishes is characterized by comprising at least three vertical piles and net cages. Two vertical piles are vertically inserted on two sides of a feeding platform, other vertical piles are inserted in a pond, the upper end of each vertical pile is overwater, and a hook is disposed at the upper end of each vertical pile. The net cages are disposed in an area surrounded by the vertical piles. The edge of a top opening of each net cage is hung on the hooks of the vertical piles, while the lower portion of the net cage is submerged. The isolation feeding device for breeding fishes is simple in structure, simple and easy to operate and low in manufacturing cost. Small fishes can access the net cages of the isolation feeding device for breeding fishes freely, while large fishes cannot. Therefore, competing on feeding between the large fishes and the small fishes is avoided, the problem of feed competition between the large fishes and the small fishes is solved effectively, and the isolation feeding device for breeding fishes is especially applicable to multiple stocking and multiple fishing, and multi-variety mixed breeding.

Description

technical field [0001] The invention relates to an isolated feeding device for preventing big fish and small fish from competing for feed, and belongs to the technical field of aquaculture. Background technique [0002] Since the reform and opening up, my country has implemented the fishery development policy of "mainly raising fish". In 2011, my country's aquaculture output reached 40.2326 million tons, accounting for 71.8% of the total aquatic product output (56.0321 million tons). The rapid development of the aquaculture industry is inseparable from the innovation of farming methods and the advancement of fishery technology. Among them, the method of round-catching and multi-species polyculture has played an important role in high-yield and efficient pond farming. Wheel catching and wheel placement means that in close-cultured fish ponds, according to the growth of fish, after a certain period of time, some edible fish that reach commercial specifications are caught, and...
