Composition of macrozoobenthos in tropical oxbow lakes of Central Kalimantan, Indonesia

Show abstractHide abstract

Composition of macrozoobenthos was studied monthly for one year in four tropical oxbow lakes along the Kahayan River, Central Kalimantan. During low water level period the abundances of macrozoobenthos in lakes Hurung and Batu (isolated from the main river) were very low whereas those were much higher in lakes Tehang and Bunter (onnected to the main river). Dissolved oxygen concentrations were much lower than the latter two. A total of 4 phylum consisting of 12 families and 20 taxa were found from these lakes with the highest number of taxa in Lake Bunter. The diversity indices of macrozoobenthos were 1.27-2.03, 1.58-2.26 and 0.81- 0.92 in lakes Tehang, Bunter and Hurung, respectively.

The impact of water hyacinth removal upon water quality by grass-carp stocking in Lake Kerinci, Indonesia

Show abstractHide abstract

In early 1990, about 80% surface area of Lake Kencil (4200 ha) was covered with water hyacinth. An experiment was conducted to identify the effectiveness of grass carp to control water hyacinth blooming in a tropical lake and related limnological changes. The fish was multiple-stocked up to 48,000 fingerlings during 1995-98. The limnological parameters were studied before, during and after the biomanipulation. Four years after the fish stocking, the water hyacinth was cleared and significant changes were observed for pH, water temperature, conductivity, BOD, COD, carbon dioxide, T-P, T-N/T-P, chl-a, NO3-N and NO2-N. Whereas DO, hardness, TN, NH4-N and total iron did not change.

Show abstractHide abstract

Physico-chemicl parameters and movement of fishes were studied in two oxbow lakes in Central Kalimantan, Indonesia to develop fishery reserve system. Sediment porosity was measured for evaluating vertical connectivity and lateral and temporal connectivity was deducted by the linkage of water level change with additional water quality parameters. The sediment porosity in the oxbow lakes varied between 64% and 85% and indicated different patterns among floodplain and oxbow lakes. Water temperature pH, dissolved oxygen, ORP and turbidity were correlated significantly with water level. Fish movement between floodplain and oxbow lakes appeared to be controlled by more complex factors.
