Embodiment Construction

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

[0018] (1) Selection and treatment of the broodstock holding tank: choose multiple areas of 300m2 2 , The earth pond with a depth of 1.5m is used as a broodstock pond, and the water filtered by 80-mesh sieve is put into the pond, each pond is equipped with an aerator, and water peanuts and bamboo strips are placed at the four corners of the water surface of the pond to tie up of mesh for concealment;

[0019] (2) Selection of broodstock: select female and male shrimps with uniform size ratio, strong vitality and health in different water systems as broodstock, the body length of female shrimp is more than 3.5cm; the body length of male shrimp is more than 4cm;

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

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