Fish sampling was conducted from March 2011 to June 2012 utilising gill nets, traps, cast net, and hook and line. A total of 34 fish species from 11 families were recorded. The Cyprinidae was the most represented with 20 species while the abundant fish was Mystacoelucus obtusirostris.

Water turbulence of the rapids increased DO levels which contributed to the higher fish diversity (H' = 2.65) at the upper reaches. The abundance of sub-adult and adult fishe, and higher fish biomass (mean = 266.52 + 580 g/hr) suggested the rapids as fish growth areas.

Fish species richness (D" = 4.67) and fish density (mean = 0.401 + 0.3 no/hr) were higher from the deeper water bodies of the middle reaches. The pools were dominated by juvenile fish and also recorded higher abundance of female fish, signifying its importance as nursery grounds. Fish diet was mainly plant material and detritus. The length-weight relationship for the 10 most abundant fish showed negative allometric growth while their condition factor, k varied from the different sampling zones.
