Mahseer  (Tor  tambroides,  Bleeker,  1854)  is  a  cultural  species  and  economic importance fish species in the Batang Tarusan River, West Sumatera. In this study morphological data was used to investigate stock identification within and among populations of mahseer. A total of 47 individuals were collected for morphology analysis in the Batang Tarusan River. Morphology analysis revealed although morphometric characteristics showed considerably greater discriminatory power to distinguish individuals from different areas than did the meristic characters, however all morphometrical and meristic showed existence analyses of mixed population among population samples. Corroborated result by meristic and morphometric analysis; there is a strong argument suggesting that the populations could be treated as a single stock unit.
