Genetic diversity of silver pomfret (Pampus argenteus) in the Southern Yellow and East China Seas

Abstract

Silver pomfret ( Pampus argenteus ) is an important fisheries resource in China, but harvest management lacks identification of management units (genetic stocks or populations). Using amplified fragment length polymorphism (AFLP), we investigated the population genetic structure of silver pomfret from the Yellow and East China Seas. In 143 individuals examined from six locations (three locations in the Yellow Sea, three in the East China Sea), a total of 194 loci were detected by six primer combinations. In all loci, 149 loci (76.8%) were polymorphic, and the percentage of polymorphic loci varied within samples from 62.9% to 67.0%. Among the six samples, Nei’s genetic diversity was 0.23 ± 0.20–0.25 ± 0.21, and Shannon’s index was 0.34 ± 0.28–0.36 ± 0.29. Analyses revealed significant genetic differentiation among the six samples, indicating at least six separate populations of silver pomfret in the Southern Yellow and East China Seas. ► We investigated genetic structure of 6 silver pomfret samples in China coast using AFLPs. ► Polymorphic loci accounted for 76.8% of total loci, and percent of polymorphic loci varied from 62.9% to 67.0%. ► Nei’s genetic diversity was 0.23 ± 0.20–0.25 ± 0.21, and Shannon’s index was 0.34 ± 0.28–0.36 ± 0.29. ► At least six separate populations of silver pomfret were in the Southern Yellow and East China Seas.
