Rapid breeding method of new fish strain

Abstract

The invention discloses a rapid breeding method of a new fish strain. The method comprises the following steps: a, selecting parent fish; b, labeling the parent; c, constructing a family; d, cultivating the family; e, determining dominant parent combination; and f, constructing a new strain. Through adopting the technical scheme, the rapid breeding method of the new fish strain can be used for breeding the new strain with relatively obvious growth domination in a short time. The technology is suitable for fishes having long sexual maturity time, such as four major Chinese carps, sturgeons and the like.

Description

technical field [0001] The invention relates to a rapid breeding method for new fish strains, belonging to the technical field of animal reproduction. Background technique [0002] Breeding is the science of studying breeding, which is to apply various genetic methods to transform the genetic structure of organisms and cultivate high-yield and high-quality varieties. In the past, aquaculture workers did not pay much attention to breeding work, often "only raising fish, not breeding". With the continuous development of science and technology, the importance of breeding has been recognized by more and more people. The aquaculture industry also has an urgent demand for improved species. Practice has proved that whether it is fish, shrimp or shellfish, species are the material basis for aquaculture production, and the selection and cultivation of improved species is an effective way to increase production. It is generally believed that when other conditions remain unchanged, t...

Problems solved by technology

Although many fish genetics and breeding work have achieved remarkable results, fish such as the four major family carp and Chinese sturgeon have a relatively long time to sexual maturity, and the progress of genetic breeding work is very slow, and it will take decades for new species to emerge
