Genetic Diversity of Giant Snakehead (Channa micropeltes) Populations Using Random Amplified Polymorphic DNA (RAPD) Markers in Sebangau National Park, Central Kalimantan

Giant Snakehead fish (Channa micropeltes, Cuvier, 1831) also known as Toman is a fish species with good taste and high market value. This study aims to reveal genetic diversity of C. micropeltes population in Sebangau National Park (SNP), Central Kalimantan using molecular analysis with genetic markers Random Amplified Polymorphic DNA (RAPD). The primers used in this study were OPE-07, OPD-03, and OPG-10. The results showed that the polymorphism of C. micropeltes in SNP waters was relatively low (43,1818%) and heterozigosity wal also not much different, i.e 0,2323 and 0,2067. Based on pairwise comparison tests (Fst,), the population of C. micropeltes in SNP waters not significantly different (P>0,05). Thus, it can be concluded that C. micropeltes in SNP waters of the Sebangau and Katingan river populations has no different genetic diversity. Genetically, C. micropeltes in SNP relatively low diversity and low adaptation capability
