Breeding method for improving estivating survival rate of cultured abalones

Abstract

The invention belongs to the field of animal heredity and breeding, and particularly relates to a breeding method for increasing the estivating survival rate of cultured abalones. The breeding method comprises the following steps: mating each male abalone with at least two female abalones, which are used as a male parent and female parents, in a cultured abalone group to propagate and cultivate an F1 filial generation group, and cultivating the F1 filial generation of each male abalone in a separating manner; performing estivating culture and cultivation on the F1 filial generation of each male abalone under the condition of a natural culturing sea area, then determining the estivating rate value (%) of the F1 filial generation of each male abalone, remaining and selecting the male parent male abalone or semen of thereof with high estivating survival rate of the F1 filial generation, then propagating and cultivating descendants by selecting and using the remained breeding abalones or the semen, and further increasing the estivating survival rate of the descendants of cultured population. The breeding method disclosed by the invention has high selection accuracy, is especially suitable for medium-scale and small-scale abalone culturing or breeding enterprises, is simple and easy to operate, and is high in feasibility.

Description

technical field [0001] The invention relates to the field of animal genetics and breeding, in particular to a breeding method for improving the survival rate of cultured abalone. Background technique [0002] Due to the scarcity of natural resources, the aquaculture industry of Baudaceae has flourished in my country in recent years and has become an important part of my country's offshore marine aquaculture industry. The breeding research on abalone mainly focuses on the crossbreeding of different geographical populations or the interspecific crossbreeding of different species of Babalaceae. The hybrid progenies often have significant hybrid vigor and resistance. The limitations of pure breeding and conservation, maintenance costs, or incompatibility restrictions such as low hybrid fertilization rate have limitations in application, especially for small and medium-sized enterprises, it is difficult to independently screen and obtain excellent hybrid parents. In the report o...
