Embodiment Construction

[0019] (2) Broodstock selection: choose female and male shrimps with uniform size ratio in different water systems, strong vitality, and health 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: Separate the female and male shrimps in the same water system selected in step (2), and then put the female shrimp and male shrimps in different water systems into the same broodstock holding pond for rearing;

[0021] (4) Breeding of broodstock: Feed once a day in the morning and afternoon. Feeding compound feed in the morning accounts for 2-3% of the body weight of the broodstock, and feeding fresh small miscellaneous fish in the afternoon accounts for 2-3% of the body weight of the broodstock; 30-50m of fresh water is added to the pool every day 3 ;

[0022] (5) Requirements for nursery pools: choose an indoor cement pool of 4m×5m×1.2m as the nursery pool, ar...

Abstract

The invention provides a method for cultivating shrimp seeds of macrobrachium rosenbergii. The method comprises: selection and processing of a parent shrimp holding pond, selection of a parent shrimp, feeding pretreatment of the parent shrimp, feeding of the parent shrimp, requirements on a nursery pond, water conditioning of the nursery pond, observation of parent shrimp mating, cultivation of larva, daily management of the nursery pond and other contents. In the water conditioning, an environment-friendly Chinese herbal medicine powder fungicide is adopted to treat the water source, so that the morbidity of the parent shrimp and the seedlings is reduced. The shrimp seed individuals cultivated according to the method of the invention has small difference and good quality. Moreover, a high survival rate of the shrimp seeds is obtained, so that the economic benefit of culturists is improved.

Description

technical field [0001] The invention mainly relates to a method for genetic breeding of shrimps. , in particular to a method for cultivating macrobrachium rosenbergii seedlings.
