Culture method for four major Chinese carps

Abstract

The invention relates to a culture method for four major Chinese carps, which comprises the steps of 1) selecting and building a pond; 2) matching fries and putting the fries into the pond; 3) feeding; and 4) carrying out other management during the breeding period. The culture method changes the culture environment with flat pond bottom required in the traditional culture method, and forms a culture environment with different water depths, different water temperatures and different aquatic organisms of the culture pond through artificial creation, thereby facilitating fish schools to freely select habitat areas, forming a nature-imitated living environment, and being conducive to the healthy growth of the fish schools. The culture method adopts a mode of overwintering in the pond and catching in the next year, thereby enabling the fish to quickly enter a growth period in the suitable season, and shortening the culture time. The number of each type of fish put into the pond is reasonably formulated by combining the culture environment, thereby forming a scientific and orderly mixed culture mode, achieving an optimal symbiotic and growth promoting aquatic environment, almost eliminating the death rate, and being rapid in growth.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a method for cultivating four major domestic fishes. Background technique [0002] At present, there are more than 30 species of freshwater fish in my country, among which green carp, grass carp, silver carp and bighead carp are called "four major fish", which are traditional excellent species in my country and are still the bulk products of aquaculture. With the continuous improvement of people's living standards and the continuous enhancement of healthy consumption awareness, traditional fishery will make great strides towards modern fishery. Transformation of growth mode, scientific utilization of resources, implementation of healthy farming, and production of safe food have become the themes of aquaculture development. [0003] However, with the gradual expansion of the scale of fish farming, many problems that have not been encountered before are gradually revealed. Many farmers ...

Problems solved by technology

[0003] However, with the gradual expansion of the scale of fish farming, many problems that have not been encountered before are gradually revealed. Many farmers use fish feed with high protein content, which is likely to cause fatty liver disease, reduce the survival rate and growth rate of fish, and in the process of breeding No, not paying attention to the changes in the water body, leading to a large number of fish deaths and other phenomena often occur
