Using macroinvertebrates as indicator of water quality in streams at different landuses in Bau, Sarawak

Species diversity of macroinvertebrate at four different landuses, namely, oil palm plantation, pig farming, settlement area and a relatively pristine stream was determined. The categories of water quality of the streams were evaluated by using macroinvertebrates as the indicator. This study used Av...
