Two-section type artificial breeding method of Exopalaemon carinicauda

Abstract

The invention discloses a two-section type artificial breeding method of Exopalaemon carinicauda. The method comprises steps as follows: disinfection treatment and water fertilization of an outdoor culturing pond, induced mature breeding of parent prawns, larva hatching and collecting, young prawn breeding in an indoor cement pond and the like, wherein disinfection treatment and water fertilization of the outdoor culturing pond comprise pond dredging, exposure under the sun, water disinfection and water fertilization; the induced mature breeding of the parent prawns refers to nutrition strengthened breeding in the outdoor pond; larva hatching and collecting refer to collection of larvas by means of phototaxis in the vigorous stage of larva hatching; young prawn breeding in the indoor cement pond refers to a conventional young prawn breeding link in the indoor cement pond after larvas are collected, counted and disinfected. The conventional young prawn breeding link is shifted forwards, outdoor earth pond cultivation and larva collection links are added, the survival rate and the utilization rate of the parent prawns are increased, selection of the superior and eliminating of the inferior of the larvas are realized, the survival rate of the larvas in the young larva breeding stage in the indoor cement pond is increased, and the young larva yield of the parent prawns per unit weight is greatly increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a two-stage artificial breeding method for white prawns. Background technique [0002] The white prawn is a bottom-dwelling shrimp in the temperate tropical sea area, with the highest yield in the Yellow Sea and the Bohai Sea. It is one of the three unique economic shrimps in China, and its output is second only to the Chinese prawn and the Chinese hairy shrimp. White prawns have strong environmental adaptability, fast growth, good meat quality, high economic value, and considerable economic benefits from farming. It is a potential shrimp species for breeding. At present, its farming output has reached one-third of the total output of polyculture ponds in the eastern coastal areas of my country. one or so. 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 cult...

AI Technical Summary

Problems solved by technology

This method of seed acquisition, on the one hand, has high cost and low emergence rate, which greatly limits the cultivation scale of white shrimp, and on the other hand, it also poses a great threat to the protection of natural germplasm resources of white shrimp, so the development of white shrimp It is necessary to study the large-scale seed development technology

Although the artificial rearing technology of white shrimp has been reported, its stable and efficient industrial seed breeding technology has not been established, and the improvement of the breeding area and production is obviously limited by the seedlings.
