| description | This study was carried out in October 2014 and February 2015 to determine the fish species composition and
water quality at Batang Ai Hydroelectric reservoir area. A total of six sampling stations were selected in this
tudy. Fourteen water quality parameters were documented based on in-situ and ex-situ laboratory analysis that
were carried out according to the APHA (2000) methods. A total of 992 individuals consisting of 20 species
from 8 families were caught in Batang Ai Hydro-electric reservoir. The three most dominant species were
Cyclocheilichti1ys apogon, Osteochilus wandersii and Barbonymus schwanenfeldii. Results for in-situ water
qual ity parameters were pH (6.22-8.32), dissolved oxygen (0.7-8.3 mglL), conductivity (6.3-120.7 !-IS/cm),
temperature (26.3-31 .3 °C), transparency (1 .02-4.27 m) and turbidity (0.00-34.66 FNU). For ex-situ water
quality parameters, results of BODs ranged from 0.7-6.3 mg/L, TSS (0.002-0.043 giL), chlorophyll-a (1.70 to
35.85 mglL) and for nutrients (ammonical nitrogen: 0.03 to 2.53 mglL; nitrate: 0.01 to 0.21 mg/L;
orthophosphate: 0.02 to 2.04 mg/L and Nitrite: 0.001 to 0.117 mg/L). The fisheries production of Batang Ai
Hydroelectric Reservoir was estimated to be 1'1.17 kg ha -I yr- I to 20.67 kg ha-I yr-I
. Aquaculture and other
anthropogenic activities occurring within the surrounding areas of the reservoir may have negatively impacted
the water quality of Batang Ai Hydro-electric reservoir. |
