    Abstract

    Pomfrets (Genus Pampus) are commercially important fishes in the Indo Pacific region. The systematics of this genus is complicated due to morphological similarities between species. The silver pomfret from Indian waters has long been considered to be Pampus argenteus. The objective of the study was to utilize the mitochondrial COI gene to establish the molecular identity of the silver pomfret distributed in Indian waters and to resolve the phylogenetic relationships among Pampus species in the world based on sequence data in the NCBI database. Seven valid Pampus species are identified in this study. The mean genetic divergence value calculated between clades representing these species was 7.9%. The mean genetic distance between the so-called Pampus argenteus from Indian waters and sequences attributed to P. argenteus from the South China Sea, where the neotype of this species was collected, was found to be greater than 12%, strongly supporting the likelihood of the Indian species being distinct. The Indian Pampus species show very close affinity to P. cinereus, with inter species differences less than 2%. The taxonomic identity of the silver pomfret in India is also discussed here, in light of molecular and morphological evidence.
