Embodiment Construction

[0017] A kind of method for industrialized seedling raising of Macrobrachium japonica, comprising the following steps:

[0018] (1) Selection and treatment of broodstock holding ponds: choose multiple areas with an area of ​​300m 2 1. An earthen pond with a depth of 1.5m is used as a temporary breeding pond for broodstock. Put the water filtered through an 80-mesh sieve into the pond. Each pond is equipped with an aerator, and water peanuts and bamboo sticks are placed at the four corners of the pond water surface. netting for concealment;

[0019] (2) Broodstock is selected: select uniform size ratio in different water systems, vigorous, healthy female and male shrimps are used as broodstock, the body length of the female shrimp is more than 3.5cm; the body length of the male shrimp is more than 4cm;

[0020] (3) Breeding pretreatment of broodstock: the female and male shrimps of the same water system selected in step (2) are separated, then, the female shrimp and male shrim...

Abstract

The invention provides an industrially breeding method of macrobrachium nipponense, comprising the steps of: selection of parent macrobrachium of macrobrachium nipponense, cultivation of fingerlings, treatment of fingerling cultivation water quality, daily cultivation management in the breeding period and the like. By use of the industrially breeding method of macrobrachium nipponense, provided by the invention, the cultured macrobrachium nipponense fingerlings have high survival rate and stable quality. According to the industrially breeding method disclosed by the invention, the problems of low survival rate and unstable quality in the conventional macrobrachium nipponense breeding process can be solved, and the economic loss of the macrobrachium culturists can be reduced.

Description

technical field [0001] The invention mainly relates to a method for genetic breeding of shrimps. , especially relates to a method for industrialized seedling raising of Macrobrachium japonica. Background technique: [0002] Macrobrachium japonicus, also known as green shrimp, is the main freshwater shrimp species cultivated in my country at present. Due to the decreasing natural resources of green shrimp, the market price has increased year by year. At present, most of the seedlings of freshwater shrimp are cultivated in earthen ponds, resulting in a seedling emergence rate. Low, unstable quality, poor survival rate in the growth process, slow growth rate and other problems, therefore, there is an urgent need for a new method of factory-raised freshwater shrimp. Invention content: [0003] The invention provides a method for industrialized seedling cultivation of Macrobrachium japonicus. The method of the invention overcomes the problems of low seedling emergence rate, uns...
