Description Narrow barred Spanish mackerel, Scomberomorus commerson (Lacepede, 1800) is one of the
economically important marine fish species in the Northern Indian Ocean. Genetic stock structuring is
reported in S. commerson from Arabian Peninsula, Indo-West Pacific, Northern Australian, Southeast Asia
and Northern Australia. The present study utilized microsatellite markers to elucidate the population
structure of S. commerson (Lacepede, 1800) in the Arabian Sea and Bay of Bengal. A total of
12 polymorphic microsatellite loci were amplified in 250 samples collected from five different geographic
locations. Low FST values (0.0023–0.027), AMOVA, PCoA and the Bayesian analysis of genetic structure
indicated unit stock of the species in Indian waters. Bottleneck analysis using Wilcoxon signed rank tests
and Mode shift test indicated lack of recent bottleneck events across populations of S. commerson. The
findings of the present study could be used in managing the commercially important species, S. commerson
as a unit stock in Arabian Sea and Bay of Bengal of Northern Indian Ocean and reinforces the need for
regional cooperation on fisheries management.
