| Summary: | A total of 23600 ha of land area (10.28%) around Sukau have been cultivated by oil
palm. The active large agriculture plantations have direct affects to the lower
Kinabatangan River and aquatic habitats around Sukau. Only 18.1% of land area
falls under Landsat TM undisturbed category. A total of 8.0% was under active land
clearing in year 2002 Landsat TM image. A total 11 families and 26 species of fish
have been identified during this study. Cyprinidae followed by Bagridae and
Siluridae represent the dominant fish species in the study area. The overall Shannon
Weiner's Index of Diversity of fish fauna in Sukau is 1.9579, while Richness Index
recorded at 2.3005 and the Evenness Index is 0.8097. In general, the fisheries aspects
in Sukau are still in small scale with low fishing efforts, thus suggesting a low
exploitation rate. Fishing activities still can be considered as only support the local
livelihoods. The in-situ water quality reads narrow range of difference at all sampling
sites and within the acceptable range of the Malaysia INWQS Class II limit. Large
scale plantations without proper mitigation measures to conserve the aquatics
environment in Sukau are perceived to have greater adverse impacts in the future. |
