摘要： Genetic parameters of three antioxidant factors, including superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX), were evaluated in liver samples from 840 Takifugu rubripes individuals from 28 full-sib families. Heritability values of SOD, CAT, and GPX were 0.17, 0.18, and 0.14, respectively, and the full-sib family effect values for these antioxidant factors were 0.46, 0.47, and 0.49, respectively. The ranges of phenotypic and genetic correlations among the three immune factors were 0.748-0.848 and 0.726-0.806, respectively. Considering the low heritability and high full-sib family effect of the three antioxidant indexes, the use of both genome-wide selection and clustered regularly interspaced short palindromic repeats (CRISPR) is promising for genetically improving the three antioxidant indexes in cultured fish. In addition, given positive phenotypic and genetic correlations among the three antioxidant enzymes SOD, CAT and GPX, the antioxidant competence of Takifugu rubripes can be improved by genetically improving these three antioxidant traits via multi-trait integrated breeding technology or indirect selection.
