Priacanthus hamrur (Forsskål, 1775), a marine perch belonging to
the family Priacanthidae commonly known as “bulls eye” has started
emerging as an important fishery resource in the trawl landings
along both the west and east coasts of India. In the present study,
genetic stock structure of P. hamrur inhabiting Indian coastal waters
was ascertained with mitochondrial DNA sequences from the
cytochrome b (cyt-b) gene using samples of the species collected in
two samplings from five different geographical locations, viz.
Chennai and Visakhapatnam (east coast) and Cochin, Mumbai and
Veraval (West coast). Partial sequence of cyt-b gene of P. hamrur
from 5 representative regions along the coastal zones was amplified
by PCR. The cyt- b marker revealed high haplotype diversity coupled
with very low nucleotide diversity within each population, as well as
low genetic distance, high gene flow, and high mitochondrial DNA
similarity among all five populations. Phylogenetic trees and pairwise
analyses demonstrated a very small divergence (0.43-0.64%)
between the populations, suggesting the lack of population
subdivisions. The overall lack of genetic subdivision among samples
was also detected by the analysis of molecular variance, and
pairwise FST values. Furthermore, the results of this study revealed a
pattern of high nucleotide homology among the adjacent populations,
and a small number of nucleotide changes among disjunct
populations, leading us to conclude that there is a genetic connectivity among the populations of P.hamrur inhabiting the coastal waters of
India.
