Abstract
There were three presumed form of Rasbora found in Lake Laut Tawar, i.e. Depik, Eas and Relo. However, their phylogenetic status was remaining unclear. For this purposes the genetic data were utilized to resolve the taxonomic ambiguity of Rasbora group in Lake Laut Tawar. Approximately 655-bp were amplified from the 5′ region of the mitochondrial cytochrome oxidase subunit I (cox1) gene using the primer pairs (Fish F1 and Fish R1). A total of 14 haplotype sequences were produced from the ingroup where haplotypes 1 to 8 were shared by Eas and Depik, and haplotypes 9 to 14 were belonging to Relo. The genetic divergence varied from 0.2 to 9.6% i.e. between Eas and Relo, 9.6% and between Depik and Relo, 9.5%. The genetic data strongly indicated that Eas and Depik should be regarded as the same species ofRasbora tawarensis.
