Abstract

Amongst the 50 largest Marine Ecosystems (LMEs) that yield 95% of the annual marine fishery revenues throughout the world, the Arabian Sea ranked 32 on a global measure. Scylla serrata is an important resource of the aquaculture and commercial fishery in the Northern Arabian Sea (NAS). The mt-DNA variations in S. serrata (n16) were estimated from the two populations: Sandspit back waters (n8) and Korangi creek mangrove areas (n8) Pakistan. The study based on 16S rRNA and Cytochrome Oxidase (COI) genes, high haplotype and low nucleotide diversity was observed in the populations of S. serrata. The neutrality tests (Tajima’s and Fu’s F’s) were non-significant, whereas mismatch analysis revealed the potential population expansion event occurred in the (NAS). Furthermore, we conducted a phylogeography analysis of S. serrata based on the COI obtained from GenBank (n47) determined from specimens of the IWP. Out of all sequences n63 (16 from Pakistan and 47 from Genbank), 46 different COI haplotypes were identified. The AMOVA indicated the phylogeographic regional partition and genetic structure in IWP. In the present study, the partial sequences of the genes provide orientation with the valuation of the genetic structure, phylogeography and genetic affiliation of S. serrata in the IWP region.
