Regulating method for promoting development of oratosquilla oratoria ovaries

Abstract

The invention relates to the field of aquaculture, in particular to a regulating method for promoting the development of oratosquilla oratoria ovaries. The regulating method is characterized by comprising the steps of selection of a culture pond structure, parent selection, water temperature regulation, lighting regulation, nutrient enrichment, daily management and the like. In the method, soil islaid on the bottom of a culture pond so as to meet the digging habits of oratosquilla oratoria, the ecological regulation requirements are met, moreover, the dog-eat-dog probability is reduced, and the parent culturing survival rate is improved; under the temperature and lighting control conditions, a lot of ovaries of female oratosquilla oratoria parents can be synchronously mature, and scaled production requirements are met; in the bait feeding process, chilled and fresh little yellow croakers, clam meat and the like are selected for nutrient enrichment, the nutritive materials which are required for the development of the ovaries are met to the greatest extent, and the ovary development quality is improved.

Description

technical field [0001] The invention relates to the technical field of aquatic breeding and breeding, in particular to a method for regulating and controlling the development of the mantis shrimp ovary. Background technique [0002] Mantis shrimp (Oratosquilla oratoria), commonly known as shrimp crawler and pipa shrimp, is a common marine economic crustacean in my country, with high nutritional value and market demand. In recent years, with the overfishing and the destruction of the offshore environment, the mantis mantis shrimp resources have been seriously declining, and the natural production can no longer meet the growing market demand. Therefore, it is particularly urgent and important to carry out research on artificial breeding and aquaculture of mantis mantis mantis shrimps. [0003] At present, researchers have overcome the artificial breeding and breeding bottlenecks of Mantis Shrimp, but it is still difficult to achieve stable large-scale breeding. The main reason...

AI Technical Summary

Problems solved by technology

[0004] The regulation of ovarian development in aquatic economic animals is mainly achieved through injection, feeding of sex hormones or their analogues, but this regulation mode also has some disadvantages, mainly due to the large injection stimulation, which may cause inflammatory reactions and lead to the risk of death; hormones There have always been food safety controversies, and the scope of use has been severely restricted. It is still difficult to regulate the ovarian development of mantis shrimps with conventional methods.

[0005] There is no report on a regulation method to promote the development of mantis shrimp ovaries by ecological regulation through methods such as fortification of feed nutrition and regulation of physical environment factors.
