THE FRESHWATER FISHES AND SPECIES STATUS OF PEAT LAND AREAS IN CENTRAL KALIMANTAN, INDONESIAHaryono and Gema Wahyudewantoro
Peat land is the unique ecosystem, it has the ability to absorb water up to nine times that volume. Therefore, the peat area becomes a source of water for the lower area and habitat of many fish species. The information about fish diversity of peat land in Central Kalimantan is limited especially from former One Million Hectares Peat land Project. The aims of this study were to assess fish diversity, abundance, potency, and species status. The study using survey methods both rainy and dry season based on catch per unit of effort (CPUE). The gears were gill net, cast net, and lift net/anco. Fish samples were preserved, then identified and deposited in Zoology Museum Bogor. The result were recorded 67 fish species belonging to 19 families, Cyprinidae is dominant family with 28 species; and recorded 47 species then totally 114 species. The fish diversity in dry season is higher than rainy season. The ranges of fish diversity among stations 5-25 species and 8-16 species in dry and rainy, respectively; St.7 is highest diversity in dry season with 25 species. Osteochilus spilurus is the most abundant (21 ind./st) during rainy and Cyclocheilichthys armatus during dry season (20 ind./st.). Mostly species potential for consume fish. Species status were 7 endemics of Kalimantan, 1 protected species (Chitala borneensis), and 1 introduced (Trichopodus pectoralis).
