Abstract
The invention discloses an aquaculture method for freshwater shrimp incubation seedling. The aquaculture method includes the following steps of: (1) aquaculture pond preparation; (2) water culture; (3) aquaculture of shrimps with eggs; (4) aquaculture of zoea; (5) aquaculture of shrimp seedlings; and (6) daily management. According to the aquaculture method, the shrimps with eggs, the zoea, and the shrimp seedlings are fed on forage with different components according to natural growth laws of freshwater shrimps in different stages, and the forage components in various stages meet the nutrition requirements of corresponding stages; based on a specific management manner, the incubation rate of shrimp eggs can reach above 96%, and the survival rate of young shrimps can reach above 95%; harmful chemicals such as pesticides cannot be used during the whole aquaculture process, so that the quality of the shrimp seedlings can be ensured; and the cultured shrimp seedlings are even in body shape, are healthy and strong in body size, are strong in disease-resistant performance, and have strong disease-resistant performance.
Description
Technical field
The invention belongs to aquaculture field, be specifically related to the cultural method of a kind of freshwater shrimp hatching nursery.
Background technology
Freshwater shrimp is one of Freshwater shrimps that economic worth is very high.Its growth is fast, and individual large, breeding is fast, and vitality is strong, is distributed widely in China's freshwater lake.Freshwater shrimp fine and tender taste is delicious, nutritious.Along with the increase of freshwater shrimp demand, increasing people starts to cultivate freshwater shrimp, but the many nutritional need of culturist to freshwater shrimp Different growth phases are not understood, unreasonable and the daily management mode of feed formula improper, cause the survival rate of freshwater shrimp hatching nursery low, bring huge economic loss to plantation family.
Summary of the invention
In order to solve the problem, the invention provides the cultural method of a kind of freshwater shrimp hatching nursery, there is incubation rate, feature that survival rate is high, and shrimp seedling growing way being good, build is healthy and strong, resistance against diseases is strong.
