Application of ecological indices using macroinvertebrate assemblages in relation to aquaculture activities in Rawang sub-basin, Selangor River, Malaysia

This study aimed to evaluate benthic macroinvertebrates assemblages using the application of ecological indices in the Rawang sub-basin of the Selangor River with reference to determining the impacts of aquaculture practices on benthic macroinvertebrates. In total, seven sampling sites were selecte...
