Problems solved by technology

Although the existing loach seed hatching and breeding are equipped with drainage and water intake functions, due to its own design defects, the water body in the pool cannot flow, especially in hot summer, such problems are more prominent. Due to the limitations of these factors , the survival rate of loach seedling cultivation is not high now, restricting the large-scale breeding of loach

Abstract

The invention provides a loach larva breeding method. A hatching pond needs to be established and is a circular cement pond. The hatching pond comprises a water inlet, main drain outlets, auxiliary drain outlets and an oxygen supplementing pipe. A boss is arranged at the center of the bottom of the hatching pond and is circular. The main drain outlets are formed in the side wall of the boss. The auxiliary drain outlets are formed in the side wall of the hatching pond. The auxiliary drain outlets are higher than the main drain outlets. The annular oxygen supplementing pipe is laid at the bottom of the hatching pond. A gas outlet is formed in the oxygen supplementing pipe. An overflow opening is formed in the top of the side wall of the hatching pond. The water inlet is located above the hatching pond, and the height of the water outlet can be adjusted. The water inlet is located above the water surface. By means of the method, water in the hatching pond can be circulated as a whole, and the survival rate is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of loach breeding and breeding, and in particular relates to a method for cultivating loach seedlings. Background technique [0002] Loach, belonging to Loach family, is small and slender, only three or four inches. And it is round in shape, short in body, with small scales under the skin, and its color is black. It is a small freshwater economic fish.
