The three-spot swimming crab Portunus sanguinolentus (Herbst, 1783) is a commercially important fishery species, widely distributed in the Indo-Pacific region. The gene diversity of P. sanguinolentus in the Indo-West Pacific region (India, Viet Nam: Nha Trang. China and Pakistan) was evaluated by using mitochondrial non coding 16S rRNA gene sequences. In 16S rRNA a total of 6 haplotypes (h) was identified from 10 sequences. The haplotype diversity (hd) was (0.889±0.075) and significantly different (P<=0.01). The nucleotide diversity (piπ) was 0.00815 ± 0.00379 and shown non-significant difference. Neutrality test Tajima’s D was estimated (D = -1.55773) and P > 0.10 negative, and no significant deviation from mutation-drift equilibrium. Evolutionary divergence in overall sequence pairs of P. sanguinolentus was 0.042 ± 0.005. The topology evaluated that P. sanguinolenus of Indo Pacific region were closely related to each other as supported by the bootstraps as gene flow is present.Journal
