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...

[0038] A method for hatching shrimp seedlings with a high survival rate, comprising the steps of:
[0039] (1) Introduction, collecting 15 domestic self-selected varieties and strains, independent breeding, sampling, virus PCR detection, leaving all negative strains as the basic population;
[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...
