 note = {Water quality, zoobenthos and epiphytic invertebrates were surveyed for waters in the peat swamp area of Central Kalimantan, Indonesia, during 22-25 February 1998. Water temperature was stratified markedly at depths of 0-1.5 m in Lekes Sabuah and Sembuluh. In Lake Sabuah, euphotic depth was as low as 0.76 m due to light attenuation by high concentration of dissolved organic matter as well as phytoplankton in the surface layer of water. Oxygen depletion was observed at bottom layers of Lake Sabuah and of northern inlet bay of Lake Sembuluh, where only a small number of zoobenthos (Oligochaeta) were collected. Water temperature was not stratified in the Kumai and Sekonyer Rivers. Dissolved oxygen concentration was low throughout the water column in the Sekonyer River. In the present lakes and rivers, biological production seemed to take place at depths of 0-1.5 m from water surface., Article, 信州大学理学部附属諏訪臨湖実験所報告 12: 81-88(2000)},
