Haplotype diversity of yellow-tail Rasbora population in Sundaland Hotspot based on COI Gene

Rasbora tornieri is known as a yellow-tail Rasbora because of its dark red tail. In Sundaland, R. tornieri is distributed in Sumatra and Kalimantan. The barrier caused by the life history between Sumatra and Kalimantan island can influence the genetic variation of yellow-tail Rasbora. Therefore, the necessary to conduct the haplotype diversity study of R. tornieri using the CO1 gene. Tissue samples of R. tornieri were collected from two populations representing upstream and downstream of  Musi River in South Sumatra. A total of 633 bp of the CO1 gene were obtained for analysis. Three haplotypes were obtained from R. tornieri individuals in Sundaland, with the low haplotype diversity value of 0.28571. The value of nucleotide diversity (π) R. tornieri was 0,00045. Overall, the values indicate the low genetic diversity and necessary to maintain also increase the genetic diversity of R. tornieri.
