Abstract

<abstract abstract-type="main" id="jai12130-abs-0001"> <title>Summary</title> <p>The silver pomfret (<italic>Pampus argenteus</italic>) is a commercially important species native to the Indo‐western Pacific area. In the present study, the genetic structure of five <italic>P. argenteus</italic> populations from the Arabian Sea, Bay of Bengal, and South China Sea were investigated using sequences of the mitochondrial cytochrome <italic>c</italic> oxidase subunit I (<italic>COI</italic>) gene. All populations showed high levels of haplotype diversity (<italic>h</italic>) and low levels of nucleotide diversity (<italic>π</italic>). Phylogenetic trees indicated that the haplotypes could be divided into three clusters, indicating the geographic distribution of the five populations. Analysis of molecular variance (<sc>amova</sc>) indicated the intra‐region variation among these populations to be highly significant. The average pairwise differences and <italic>F</italic>_st values among the three regions were also found to be significant. These results suggest that <italic>P. argenteus</italic> in these regions has strong geographic genetic structure. The present results provide new information for the genetic assessment, fishery management, and conservation of this species.</p> </abstract>
