Installation healthy high-yield culture technique of clarias leather

Abstract

The invention relates to an installation healthy high-yield culture technique of clarias leather, which is a method for adopting a series of effective specifications and rules for the problems of culture ponds, culture water, fingerling throwing, bait feeding, feed selection, water quality management and the like. By using the technique, high yield can be achieved, and the culture volume of the technique can reach the clarias leather yield above 400 kilograms in per cubic water body and can reach the culture yield above 250 kilograms in per cubic water body in a shallower cement pond; the technique can realize annual culture by using a heat supply facility and a greenhouse, and the highest survival rate is 95% through statistics.

Description

technical field [0001] The invention belongs to a special fish breeding method, in particular to a healthy and high-yield breeding method of leather beard catfish. Background technique [0002] Leatherbeard catfish belongs to Siluriformes, which is a freshwater cultured fish introduced from Africa to my country. It grows fast, has high yield, and is suitable for high-density farming. However, as a warm-water fish, its suitable growth temperature is 25°C-30°C. The season in the northern region where the water temperature reaches above 20 degrees is only 4 months, resulting in a short period of breeding and growth, which greatly limits the growth and output of leatherbeard catfish. At the same time, due to the low price of the species itself, the main type of feed is the frozen or freshly slaughtered offal of chickens and ducks. The content is high, and the feeding intensity of fauna fish is high, resulting in the accumulation of fat in the viscera and liver of the fish, and t...

At the same time, due to the low price of the species itself, the main type of feed is the frozen or freshly slaughtered offal of chickens and ducks. The content is high, and the feeding intensity of fauna fish is high, resulting in the accumulation of fat in the viscera and liver of the fish, and then the formation of fatty liver, and the decline of the health level of the fish. The resulting decline in health levels leads to death in a stressful state, which affects the breeding efficiency
