Abstract
Sequence variation of the mitochondrial control region in silver pomfret (Pampus argenteus) among six populations from the Indo-West Pacific region was analyzed. A total of 309 polymorphic sites were detected in the 464–466 bp segment of the control region among 165 individuals which defined 72 haplotypes. Haplotype diversity was ranged from 0.800 to 0.943 and nucleotide diversity ranged from 0.333% to 1.886%. Genetic distance and the fixation index indicated significant differences among populations in different geographical groups (P < 0.05). Median-joining network analysis data showed distinct patterns of phylogeographic structure. The present results suggested that P. argenteus populations have developed significant genetic structure, especially among geographically isolated groups.
