Breeding method of channa asiatica

Abstract

The invention relates to a breeding method of channa asiatica. Clean mountain spring water serves as a breeding water source of the channa asiatica, and the water temperature is kept constant within 1-3 DEG C; according to the breeding density of the channa asiatica, at most ten channa asiatica are bred per cubic meter; in the feeding process, living river prawns are scattered once a week, and at least 150 jin of river prawns are scattered per mu of water area in each week; 100-120 crucian carps are bred at the same time per mu of water surface. One part of the released living river prawns are used for feeding the channa asiatica, and the other part of the released living river prawns are used for self-growing; the crucian carps bred cooperatively can digest excreta of the channa asiatica, clear away corpse residues of the river prawns and keep the water clean, so that a micro-ecological cycle system is formed, and growth of the channa asiatica, the river prawns and the crucian carps is promoted.
