Environmental influences on fish assemblages of the Upper Sungai Pelus, Kuala Kangsar, Perak, Malaysia
This study evaluates the current environmental influences on fish assemblages of the upper Sungai Pelus, Kuala Kangsar, Perak. Fish samplings and habitat characterizations were conducted at three significant different months, which were on dry (June 2014), wet (August 2014) and moderately wet season...
