Embodiment 1

[0023] A method for hatching shrimp seedlings with a high survival rate, comprising the steps of:

[0024] (1) Introduction, collecting 10 domestic self-selected varieties and strains, independent breeding, sampling, virus PCR detection, leaving all negative strains as the basic population;

[0025] (2) raising, rearing to parent shrimp, preferably going out vigor is strong, body surface is smooth, without deformity, body weight is greater than more than 20% of average body weight as standby parent shrimp;

[0026] (3) family establishment, utilizing artificially transplanted male shrimp sperm pods, 100 self-breeding and cross-breeding families were established within 5 days, among which 50 half-sib families were established;

[0027] (4) Independent cultivation of families, shrimp seedlings are cultivated to P5~7 stages, families are raised independently, seed preservation and testing are separated, P5 seedlings of each family are randomly divided into three parts, and seedli...

[0040] (2) raising, rearing to parent shrimp, preferably going out vigor is strong, body surface is smooth, without deformity, body weight is greater than more than 20% of average body weight as standby parent shrimp;

[0041] (3) family establishment, utilizing artificially transplanted male shrimp sperm pods, 120 self-breeding and hybrid families were established within 5 days, of which 60 half-sib families were established;

[0042] (4) Independent cultivation of families, shrimp seedlings are cultivated to P5-7 stage, families are raised independently, seed preservation and testing are separated, P5 seedlings of each family are randomly divided into three parts, and seedlings are preser...

Embodiment 3

[0053] A method for hatching shrimp seedlings with a high survival rate, comprising the steps of:

Abstract

The invention relates to the technical field of shrimp seed incubation, in particular to a high-survival-rate shrimp seed incubation method. The method comprises the following steps of (1) introduction, (2) feeding, (3) family establishment, (4) family independent cultivation, (5) target family determination, (6) variety breeding, (7) cultivation, (8) artificial egg collection, (9) incubation management and (10) shrimp seed management. Through hybrid breeding of a family, seed shrimps with high salt, temperature and disease tolerance are bred, and the common problems of low survival rate and the like of shrimp seeds are effectively solved in the incubation process of the shrimp seeds and in shrimp seed management.

Description

technical field [0001] The invention relates to the technical field of shrimp hatching, in particular to a method for hatching shrimp with a high survival rate. Background technique [0002] The adult Penaeus vannamei can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps. It is a wide-temperature and wide-salt tropical shrimp. [0003] Penaeus vannamei is the shrimp species with the highest yield among the three major cultured prawns. It is mainly distributed in the tropical waters of the western Pacific coast of the United States, from the Gulf of Mexico to the central part of Peru, and is more concentrated in the waters near Ecuador. It is one of the three most productive species in the world. Penaeus vannamei has a thin shell, its normal body color is blue, and it has no markings all over its body. Its shape is similar to tha...
