AB The Way Petai River provides a lot of local services ranging from the provision of fish household water bathing washing clothes irrigation and playground for children. Maintaining a reasonable good water quality is important for most of these uses. One way to assess water quality is to quantify abundance and diversity of macro-invertebrates. (Macro-invertebrata are invertebrate animals visible to the naked eye (> 0.5 mm) such as insects worms crustaceae.) Various groups of macroinvertebrates have different tolerance to variations in water quality and can thus be used as indicator.
