Abstract

The mahseer (Tor tambroides) is an important commercially fishes in Indonesia. Here we-analyze DNA sequence data from the Cytochrom Oxidase Subunit 1 (COI) of the mitochondrial-genome to estimate genetic effective female population size (Nef) of mahseer in Manna River,-Bengkulu Province and Tarusan River, West Sumatra Province. The aim is to compare the effective-female population size and population history of giant mahseer from two rivers which constitute-different status of population and what could be fuel from the information. Samples obtained from the-year of 2011-2012. The molecular data, a stretch of 628 nucleotides (Manna specimens) and 706-nucleotides (Tarusan specimens) of COI of mtDNA were used to investigate effective female-population size (the formula theta (Ǿ) = 2 Nef V) and population history of mahseer. Population history-of mahseer was generate through growth module and neutrality test in DnaSP3.51 to yield mismatch-distribution plot. Our results show that despite this reduction, the effective female population size of-both populations is sufficient to survive from a genetic viewpoint. However, we have been able to-show that protected population is much more likely to be higher Ne or individuals than the-unprotected population. Therefore, ongoing conservation efforts remain worthwhile. The historic-population expansion of the mahseer (inferred from this study) may indicate a non possible reexpansion in the future of the current population of the mahseer. It is possible for the mahseer to-extinct if the mahseer population continues to decline and the necessary conservation actions are not-taken.
