| Summary: | A study was carried out to document the fish composition and diversity as well as selected
water quality parameters at Peraran and Punan Bah, Batang Rajang, Kapit due to the lack
of published information on these two areas. Eight stations were selected from downstream
area (Peraran) and nine stations from upstream area (Punan Bah). Fish sampling gears
such as monofilament gill nets of different mesh sizes, three-layered nets, cast net, electroshocker
device and scoop nets were used. A total of 916 fish individuals were caught from
all stations with Cyprinidae as the dominant family (75.8 %), followed by the family
Balitoridae (8.2 %), Siluridae (7.9 %), Bagridae (3.3 %), Pangasiidae (2.1 %), Channidae
(1.0 %), Pristolepididae (0.8 %), Zenarchopteridae (0.6 %), Cobitidae (0.2 %),
Mastacembelidae (0.1 %), Osphronemidae (0.1 %) and Sisoridae (0.1 %). The dominant
species recorded was Rasbora rutteni with 140 individuals, followed by Cyclocheilichthys
apogon with 94 individuals and Rasbora lateristriata with 89 individuals. The downstream
area of Peraran, Batang Rajang has higher species composition and diversity (1.77)
compared to the upstream area (1.66). |
