Abstract

The island of Kalimantan, known as Borneo to the international community, consists of three allied countries, namely Sarawak, Brunei Darussalam and Indonesia. In this part of the island there is an Indonesian territory whose northern part is directly adjacent to Sarawak and the Natuna Sea, the area is the Province of West Kalimantan. West Kalimantan province covers an area of 421,891 km2 and has hundreds of small and large rivers. The number of river flows in this province makes West Kalimantan province one of the provinces known as the area of a thousand rivers. The existence of the river is the soul of the people of West Kalimantan from the past until now. The Peniung River is one of the rivers located in Ribang Kadeng Village, Kalis District, Kapuas Hulu Regency. This river crosses the villages of Ribang kadeng and Na'sebintang (Nanga Sebintang) and flows into the Mandai River at the village of Na' Peniung. Information related to the diversity of fish species is necessary for the sustainable management of fishery resources. With this information, of course, the determination of policies and decision-making in the process of water resource management or use of hydrographic basins can be carried out correctly. However, the reality he is facing today is the lack of information on the diversity of freshwater fish, especially from the West Kalimantan region. This study managed to obtain 126 individuals of freshwater fish consisting of 10 families and 15 species. The diversity index obtained is moderate, index of Evenness is high and there are no dominant species.
