Identification of Diversity and Potential of Freshwater Fish Species in the Peatlands of Sembakung, North Kalimantan

Abstract

Sembakung River is one of the important river ecosystems in North Kalimantan. Based on the parent material, the soils along the Sembakung river basin consist of peat soil and mineral soil. With its unique characteristics, this river has quite high potential resources in public waters, especially fish and other aquatic biota. The purpose of this study was to identify and identify the diversity of freshwater fish species that exist in peatland areas. Found 11 types of fish along the Sembakung River. These fish species come from Familia Siluridae, Cyprinidae, Cannidae, Eleotridae, Pangasiidae, Bagridae and Helostomatidae. The highest relative abundance (Kr) was the Salap beruntus (Barbonymus gornionotus). The most common type of fish found (Fi) was white Lais fish, 58.3% Fi and the least common were Toman (Channa micropelte), black Betutu (Oxyeleotris selheimi) and Red Betutu (Oxyeleotris marmorata).
