AI Technical Summary
The existing grouper breeds lack the ability to resist hypoxia, resulting in slowing growth rate, decreasing immunity, prone to disease and increasing economic losses in low-oxygen environments. Traditional aerobic methods are costly and have a great environmental impact.
Groupers with anti-hypoxic traits are cultivated through parenting selection, hypoxia domestication, insemination and hatching, juvenile fish screening and molecular marker assisted breeding. The specific steps include hypoxia domestication pond domestication, dissolved oxygen control, parenting and juvenile fish selection and molecular marker detection, and the target genotypes are TT and GG.
The cultivated grouper can survive and grow normally in a low-oxygen environment, reduce the risk of death, reduce the use of aerobic equipment and chemical agents, reduce costs and improve economic benefits.
