Freshwater fish in Kalimantan is the highest among Indonesian islands, with many endemic species. Therefore, a fish population study was conducted in Lake Siawan, West Kalimantan, for the purpose of determining fish diversity, abundance, local distribution, species status, and its habitat. Five sampling stations were designated and the catch per unit of efforts (CPUE) approach was adopted to get the samples. The fish caught were counted to get the species diversity and abundance. There were 57 species from 13 families that were recorded, with Cyprinidae as the dominant family with 34 species, followed by Bagridae with 4 species. Station 1 and station 5 were recorded as the highest and the lowest fish diversity, respectively. The most abundant species were Brevibora dorsiocellata and Rasbora tornieri . Four species has wide distribution and almost all of the fish found was native species. Three endemic species recorded were Hampala bimaculata, Leptobarbus hosii and Puntigrus anchisporus .
