Abstract
Osteobrama belangeri is an important medium carp endemic to Manipur state in India Myanmar and Yunnan Province of China. Although the species is listed as Near Threatened species according to IUCN status with sizeable population available in Myanmar, it is Extinct in the Wild in Manipur. An 842 bp segment ATP synthase 6/8 region of mtDNA was sequenced and analysed for 56 O. belangeri individuals. Analysis of population differentiation showed no significant genetic differentiation between the four sampling localities (ΦST = −0.034, p = 0.819). Results were further corroborated by a non-significant nearest neighbour statistics (Snn = 0.223, p = 0.897) and exact test of population differentiation (p = 0.893). Phylogeographic analysis revealed two haplogroups, but there was no obvious phylogeographic pattern separating the sampling localities. The present study suggests a single panmictic population of O. belangeri in Indian region.
