Cobia, Rachycentron canadum, is an economically important migratory fish distributed in
tropical waters worldwide and is a candidate fish species for aquaculture practices. The genetic
stock structure of R. canadum distributed along the Indian waters was identified using
mitochondrial ATPase 6 and 8 genes. A total of 842 bp sequence of ATPase 6/8 genes obtained
in this study revealed 15 haplotypes with mean low nucleotide diversity (�¼0.001) and high
haplotype diversity (h¼0.785). AMOVA indicated the genetic differentiation of 90.47% for
individuals within the population. This is well supported by co-efficient of genetic differentiation
(FST) values obtained for pairwise populations that were low and non-significant with an
overall value of 0.002. The parsimony network tree revealed star-like phylogeny and all the
haplotypes were connected with each other by single mutational event. The findings of the
present study indicated the panmixia nature of the species which can be managed as a unit
stock in Indian waters.
