“…This could be explained by some ecological or environmental factors such as major physical barriers, pollution or reversals in the monsoon-driven surface water current systems (Dale 1956). Similar findings were reported by Khamnamtong et al (2009) and Mandal et al (2012). Also in Australia (Benzie et al 2002), low levels of population genetic differentiation in wild P. monodon were evident over distances of hundreds or thousands of kilometers, except where major biogeographical boundaries acted to disrupt gene flow.…”

Quality production of the shrimp Penaeus monodon in hatchery operations depends heavily on the evaluation of genetic diversity and population structure of brood stocks. Mitochondrial DNA (mtDNA) sequences have been widely used to study genetic variability and relationships in many crustacean groups, and these same markers may be incorporated into evaluation studies of shrimp broods and populations. For this purpose we looked at variation in mitochondrial D-loop sequences as an indicator of genetic diversity in shrimp populations from a region of India that represents the main sources of new material for brood stocks. In our study of these populations the overall mean genetic diversity was 0.191. The highest level of genetic diversity (0.357) was observed in the Kakinada population, whereas the lowest diversity (0.0171) was observed in the Nellore population. The results also indicate that overall, the populations along the Andhra Pradesh coast are genetically diverse despite the fact that there is considerable gene flow between them. From the results, it is evident that east cost of India shows high genetic diversity among P. monodon broods and no evidence of loss of diversity due to excessive inbreeding. The fact that the genetic variability of these populations has been maintained, despite ten years of dependence on these broods, shows that at the present time there is no indication of over exploitation.Electronic supplementary materialThe online version of this article (doi:10.1186/2193-1801-2-671) contains supplementary material, which is available to authorized users.

“…Mostly, lower levels of genetic differentiation are reported in marine fishes due to higher dispersal potential during planktonic egg, larval or adult by life history stages, coupled with an absence of physical barrier to movement between ocean basins. The continuously changing coastal current pattern also may result in exchange of larvae along the Indian coast, resulting in low population genetic differentiation (Mandal et al, 2012). Sun et al, (2012a, b) found high genetic divergence between pomfrets from Mumbai, India (Arabian Sea) and Ngao, Thailand (Bay of Bengal) and concluded that the mainland of India blocks genetic exchange between Bay of Bengal and Arabian Sea.…”

Mitochondrial ATPase 6/8 genes to infer the population genetic structure of silver pomfret fishPampus argenteusalong the Indian waters

Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species. The genetic stock structure of P. argenteus distributed along Indian coast was identified using analysis of 842 bp of complete ATPase 6/8 genes of mitochondrial DNA. Altogether, 83 silver pomfret (P. argenteus) collected from 4 locations along Indian coast (Gujarat, Kerala, Tamil Nadu and West Bengal) were sequenced. Twenty four haplotypes were identified among 83 individuals with haplotype diversity (0.87) and nucleotide diversity (0.0025). The significant pair-wise F ST and AMOVA values, between samples from West Bengal (east coast) and other locations along the west coast (Gujarat and Kerala) indicated the occurrence of distinct population structure in silver pomfret along the coast.

“…Statistically significant low F ST values showing the weak genetic differentiation of S. commerson between the locations may be attributed to higher larval and adult stage dispersal together with the non-existence of a physical barrier for movement between ocean basins. In oceans, the coastal current is continuously changing and this phenomenon may be resulting in the exchange of larvae and finally in low population genetic differentiation (Mandal et al, 2012). This low differentiation is also indicating that high level of gene flow is there between Bay of Bengal and Arabian Sea for these highly migratory fishes.…”

Scomberomorus commerson is an economically important migratory fish distributed worldwide. The genetic stock structure of S. commerson 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 23 haplotypes with mean low nucleotide diversity and high haplotype diversity. Co-efficient of genetic differentiation (FST) values obtained for pair wise populations were low and non-significant with an overall value of -0.02074. The high haplotype and low nucleotide diversity values together with mismatch distribution analysis suggested a history of genetic bottleneck events or founder effect, with subsequent population expansion in S. commerson. The findings of the present study indicated the panmixia nature of the species which can be managed as a unit stock in Indian waters.
