Abstract

The study was conducted in the river system located at Wilmar palm oil plantation. The objective of this study is to determine the diversity and abundance of freshwater fish fauna. Nine sampling sites were selected and the fish samples were collected using three-layer gill nets, cast nets and scoop nets. There were total of 503 individuals of samples were collected; the dominant fish species was Cyclocheilichthys apogon under Family Cyprinidae whereas the dominant crayfish species was Cherax quadricarinatus under Family Parastacidae were identified at the sampling sites. There are 35 fish fauna species identified, two from those species was endemic species such as Nematabramis everetti and Puntius collingwoodii, and three were exotic species such as Cherax quadricarinatus (red-claw crayfish), Macrobranchium rosenbergii (Giant freshwater prawn) and Oreochromis niloticus (tilapia), total there were 32 native species. The highest number of fish samples obtained was at Station 8 which covers 57.65% from the overall samples whereas the least number of samples was at station 6 which covers only 12.92%. There were six types of physicochemical parameters were taken and analyzed using oneway ANOVA. The result shows there was significant difference between physicochemical water quality parameters.
