FRESHWATER FISH ASSEMBLAGES ON THE ISLANDS OF BUTON AND KABAENA, SULAWESI, INDONESIA
Dr. David J. Bird
Abstract
As a relatively isolated part of Indonesia, Sulawesi has an interesting biogeography and a high proportion of endemic species. Following an initial survey of the freshwater and estuarine fish of Buton Island, in south-eastern Sulawesi in 2001 (BES SEPG 1943), the work was extended in 2002 to include Kabaena Island and the upper reaches of rivers in the mountainous regions of both islands. A total of 26 sites were sampled by electrofishing or by Seine netting. Species accumulation curves suggest the majority of freshwater fish that inhabit these islands have now been collected. Species of Gobiidae dominate the collections, and several species obtained in 2002 may be new to science. Additional taxonomic work will be required to confirm their identity. Canonical Correspondence Analysis was used to examine the relationship between the fish present in each sample and the local environmental characteristics at each site. Initial results suggest this and other statistical techniques will help establish the most important characteristics that determine the fish assemblages at different sites. The information will be invaluable in forming management plans for the conservation of rivers in the proposed rainforest reserves.
