Cultivation method of young freshwater shrimps

Abstract

The invention discloses a cultivation method of young freshwater shrimps and belongs to the technical field of freshwater cultivation. The method includes steps such as young shrimp cultivation pond selection, early preparation, parent selection, parent cultivation and mating and young shrimp cultivation. A cultivation pond comprises a pond body, three circles of water inlet pipes are arranged onthe inner wall of the pond body, the water inlet pipes are circumferentially distributed on the inner wall of the pond body in an equal-distance manner, water guide pipes are arranged along the tangential direction of the cross section of the pond body, and the water discharge directions of two opposite water guide pipes are opposite. The method has the advantages that the living environment of the young freshwater shrimps can be simulated to allow the cultivation pond to adapt to the living habits of the young freshwater shrimps, a good environment is provided for the growth of the young freshwater shrimps, the special requirements of inhabiting, ingestion, growth and reproduction can be satisfied to increase the survival rate of the young freshwater shrimps, feeding is performed differently according to different time periods to satisfy the nutrient requirements need by young freshwater shrimp growth, and different feed is used for feeding according to a certain proportion to improvethe quality of the young freshwater shrimps.

Description

technical field [0001] The invention relates to the technical field of freshwater aquaculture, in particular to a method for cultivating freshwater freshwater shrimp seedlings. Background technique [0002] Freshwater aquaculture refers to the use of nursery ponds, reservoirs, lakes, rivers and other inland waters (including brackish water) to raise and reproduce aquatic economic animals (fish, shrimp, crab, shellfish, etc.) An important part of the land and water industry. The fishes are mainly cultured, the shrimps cultured include Macrobrachium rosenbergii and Hainan prawns, and the crabs cultured are mainly river crabs. At present, China's freshwater aquaculture fish mainly include: herring, grass carp, silver carp, bighead carp, carp, crucian carp, bream, bream, dace, non-crucian carp and other economic fish. The area and output of freshwater aquaculture in China rank first in the world. [0003] The freshwater shrimp belongs to the Arthropoda phylum, Crustacea, Deca...

AI Technical Summary

Problems solved by technology

[0004] The current artificial breeding techniques for freshwater shrimp are still relatively traditional, especially in the cultivation of freshwater shrimp seedlings, the disease is serious, and the survival rate of cultivation is extremely low, which seriously hits the farmers' desire and enthusiasm for cultivation.

In the process of cultivating freshwater shrimp, when it is necessary to change the water in the cultivation pond, due to the small size of freshwater shrimp seedlings, it is easy to escape and kill the shrimp seedlings, which is easy to occur when using a filter with a smaller mesh.
