Optimum selection method of wild parent of autumn shrimp of Marsupenaeus japonicus and fundamental group morphological model obtaining method

Abstract

The invention relates to an optimum selection method of a wild parent of an autumn shrimp of Marsupenaeus japonicus and a fundamental group morphological model obtaining method. Marsupenaeus japonicus summer wild individual shrimps having the body types meeting a morphological model equation of a Marsupenaeus japonicus autumn shrimp high-quality wild parent selection fundamental group are selected into an autumn shrimp high-quality wild parent fundamental group; after artificial ripening promotion and culture, female shrimps that have characteristics of bright and clean body surfaces, bright and transparent shells, bright body colors, complete appendages, healthy states with no disease and no damage, quick reaction, good gonad development, and long body lengths larger than or equal to 16cm are selected as Marsupenaeus japonicus autumn shrimp breeding parents. Therefore, the overwintering breeding survival rate of the Marsupenaeus japonicus autumn shrimps is effectively improved.

Description

technical field [0001] The present invention relates to a method for optimizing the wild parent of Penaeus japonicus autumn seedlings in the aquaculture industry and a method for obtaining the morphological model of the basic group, in particular to a method for optimizing the autumn seedlings of Penaeus japonicus in the East China Sea region, which belongs to agriculture The technical field of shrimp aquatic biological farming in aquaculture. Background technique [0002] Japanese sac shrimp (Marsupenaeus japonicus), also known as Japanese prawn, commonly known as "bamboo shrimp", "flower shrimp", etc., belongs to Arthropoda, Crustacea, Decapod order, Penaeidae, native to Japan, China, Philippines, Australia and other countries , is a warm-water benthic shrimp widely distributed in India and the Western Pacific, with the habit of overwintering and migrating. Because of its bright body color, delicious meat, high nutritional and economic value, rapid growth, strong stress r...

AI Technical Summary

Problems solved by technology

So far, the phenotypic selection of wild parents of aquaculture animals at home and abroad is relatively shallow. Generally, it is generally expressed as requiring physical integrity, no disease, no injury, and quick response, and the lower limit of weight and body length specifications has been stipulated, but no consideration has been given. Due to the fact that the wild parents and their bred offspring have different survival strategies due to the huge difference in the environment, the selection accuracy of the wild parents is obviously low, and the survival quality and growth performance of the offspring are not ideal.
