Breeding method of palaemon carinicauda rich in astaxanthin

Abstract

The invention discloses a breeding method of palaemon carinicauda rich in astaxanthin. Specifically, natural palaemon carinicauda of which the body color is red is selected as a breeding parent, through directional mating and a group selection and breeding technology, the red body color character is selected and purified, a new palaemon carinicauda variety which is red and rich in the astaxanthinis bred, and large-scale breeding is achieved. Palaemon carinicauda bred through the breeding method has the advantages that the whole body is red, the content of the astaxanthin is high, and the additional value of commodities is high, the principle of the breeding method is feasible, the process is simple, the cost input is low, the nutritional value and additional value of the product are high,and the culture benefit is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of cultivating seawater shrimp varieties, and in particular relates to a method for cultivating white prawns rich in astaxanthin. Background technique [0002] The white prawn is a demersal shrimp in warm and tropical seas, with the highest yield in the Yellow Sea and Bohai Sea. White prawns have strong environmental adaptability, fast growth, good meat quality, high economic value, and considerable economic benefits from farming. They are very potential species of shrimps for breeding. At present, their farming output has reached three thirds of the total output of polyculture ponds in the eastern coastal areas of my country. about one-third. White prawns are resistant to low temperature and suitable for a wide range of salt, and can be cultured in freshwater ponds after desalination. It has a wide range of culture and great potential. [0003] In recent years, with the continuous increase of the breeding ...

AI Technical Summary

Problems solved by technology

At present, the cultured seedlings of white prawns are mainly obtained by collecting seedlings in natural sea areas, catching natural seedlings, or directly stocking ovipositous shrimps in culture ponds. The quantity and quality of seedlings are greatly affected by the external environment, and the existing seedlings are all undeveloped. Domesticated and selected wild shrimps, and even artificially cultured overwintering shrimps, tend to have slow growth, poor resistance to stress, and obvious differences in the specifications of commercial shrimps, which significantly reduces the economic benefits of farming.
