Description

A kind of cultivation device for perch fry

technical field

The utility model relates to a cultivating device for perch fry, belonging to the technical field of aquaculture.

Background technique

Perch, also known as flower perch, is listed as one of the "Four Famous Freshwater Fishes in China" together with Yellow River carp, mandarin fish and Heilongjiang Xingkai Lake big white fish. The flesh of perch is white, fat and tender, with few fine thorns, no fishy smell, very delicious taste, rich in protein and vitamins, and is an important economic breeding species in my country. In the process of perch farming, a large amount of harmful substances can easily accumulate in the equipment or the bottom of the pond. These harmful substances will not only cause water pollution, but also lead to the spread of various diseases, bringing certain risks to perch farming. Especially the perch fry in the seedling period have poor anti-stress ability and are easily sick or even dead.

At present, the sewage of aquaculture ponds is mainly realized by artificial siphoning or changing ponds, which not only changes the amount of water, but also easily damages the seedlings, causing them to produce stress responses, which is not conducive to improving the survival rate of seedlings. In the prior art, the patent application with the publication number CN208798547U discloses a resource-saving fish fry running water cultivation device, which includes a basin body, a collection box is arranged under the basin body, and a sewage pipe is movably installed at the lower end of the collection box, and the collection box is a funnel. In this way, the filth produced in aquaculture is concentrated at the lower end of the collection box, so as to facilitate the centralized treatment of filth and garbage and reduce the water consumption in the process of sewage discharge. However, since the sewage pipe is located at the lowest point in the center of the collection box, the main area of water flow during sewage discharge is the center of the collection box, and the water flow near the side wall of the collection box is relatively less fluid. When the water flow is difficult to flush the dirt into the sewage pipe, it is difficult to clean the collection box. At the same time, the direction of water outlet is relatively concentrated, which easily leads to high water outlet pressure, so that the fry in the basin are greatly affected by the water flow, which is not conducive to the healthy growth of bass fry.
