Abstract

The invention provides a breeding method of channel catfish. The method comprises the following steps: (1) selecting a pond; (2) finishing the pond; (3) disinfecting and pretreating the pond; (4) stocking fries; (5) carrying out breeding management. The breeding method of channel catfish disclosed by the invention has the technical effects that a good living environment is provided, the survival rate is increased, and can reach 90%, and smooth breeding is ensured. An organic fertilizer and a microbiological feed additive are cast to the pond, the micro-ecological environment of the breeding pond is effectively improved, water is purified, and the disease resistance is enhanced.

Description

technical field [0001] The invention relates to a method for cultivating channel catfish, which belongs to the technical field of aquaculture. Background technique [0002] Channel catfish, also known as channel catfish, belong to the Siluriformes and Catfish family. Channel catfish is a species of catfish introduced by the Hubei Provincial Institute of Fishery Sciences at the same time as cloud catfish in 1984. After several years of research and promotion of breeding, it has been confirmed that this species of fish is suitable for breeding in most areas of China. In recent years, it has developed rapidly, the aquaculture area has expanded rapidly, and the economic and social benefits have been remarkable. It has become one of the important industries of mariculture in my country. [0003] At present, there are mainly the following problems in the breeding of channel catfish: slow growth, high incidence of diseases, and irregular specifications. Therefore, the further...
