GENETIC VARIATION OF Tor tambroides (Bleeker, 1854) ALONG BATANG TARUSAN RIVER, WEST SUMATERA: IMPLICATIONS FOR STOCK IDENTIFICATION
Abstract: Mahseer (Tor
tambroides, Bleeker, 1854) is an important consumption fish species in the
Batang Tarusan River, located in the West Sumatera, Indonesia. In this study
the CO1 of mtDNA sequence data were used to investigate genetic variability
within and between populations of mahseer. Twenty four tissue samples were
collected for genetic analysis in the Batang Tarusan River. Genetic analysis
revealed two different haplotypes were existed. The overall nucleotide and
haplotype variability were low in all sampling sites. Hierarchical AMOVA
analysis showed that mahseer populations form a single panmictic population
with low FST= 0.02794; p = 0.418 and high gene flow among population sampling.
Corroborated result by genetic analysis; there is a strong argument suggesting
that the populations could be treated as a single stock unit.
