Fish aquaculture equipment

Abstract

The invention discloses fish aquaculture equipment. The fish aquaculture equipment comprises a first aquaculture box, a second aquaculture box, an inclined channel, an ozone generator, a first aerator, a water outlet, a water discharge valve, a sedimentation tank, a filtering tank, a circulating pipeline, a pump and an extraction pipe. An end of the extraction pipe penetrates through the top of the second aquaculture tank, and a spray head is vertically arranged downwards in the second aquaculture tank; a plurality of turbulent flow pipes are arranged below the spray head, and a plurality of through holes are penetratingly formed in the lower ends of the turbulent flow pipes; the two sides of the turbulent flow pipes are symmetrically provided with water turbines, and the bottom of the second aquaculture box is provided with an air pump; and the output end of the air pump penetrates through the bottom of the second aquaculture box, and a second aerator is vertically arranged upwards inthe second aquaculture box. Fishes are attracted to actively flow from the first aquaculture box to the second aquaculture box, while concentrated breeding is realized, the fat content of the fishesis reduced, the muscle quality of the fishes is compact, and the taste and mouthfeel of the fishes are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish breeding equipment. Background technique [0002] In order to improve economic benefits, the current freshwater fish breeding mainly adopts the mode of centralized breeding. Intensive farming mainly uses net cages and other equipment to place a large number of fish in net cages for farming. However, the activity space in the net cage is small, and a large amount of fish is raised in the net cage, which will cause a serious shortage of the movement space of the fish. In crowded spaces, still water conditions, and regular feeding, the fish themselves will not actively move. Lack of exercise leads to high fat content of fish in cages, and the muscle quality is not tight. Compared with fish grown under natural conditions, its taste and taste are quite different from those of fish grown under natural conditions. Moreover, because the water body is in a relatively static s...

Lack of exercise leads to high fat content of fish in cages, and the muscle quality is not tight. Compared with fish grown under natural conditions, its taste and taste are quite different from those of fish grown under natural conditions. Moreover, because the water body is in a relatively static state, it is easy to reduce the oxygen content and water quality. become worse, thereby reducing the survival rate of fish
