The genetic structure of wild and cultivated populations of Pseudosciaena crocea
大黄鱼野生与养殖群体遗传结构的比较研究

Genetic structures of wild and cultivated populations of Pseudosciaena crocea were investigated using the assay of vertical slab polyacrylamide gel electrophoresis. The results showed that the mean effective number of alleles per locus (Ae) ranged from 1.1250 to 1.1293, the percentage of polymorphic loci (P) ranged from 12.50 % to 18.75 %, the observed heterozygosity (Ho) was 0.1250, and the expected heterozygosities (He) ranged from 0.0636 to 0.0677. The genetic differentiation among P. crocea populations was low. Genetic distance a among populations ranged from 0.0000 to 0.0001, genetic differentiaion index (Fst) among populations was 0.0004, and gene flow washigh (Nm =609.6667).
