Summary: | A study was carried out to document the status of reservoir fisheries including water quality and
fish fauna at Batang Ai Reservoir due to the lack of published information. Twelve sampling
stations were selected for fish and water sample collection. Results shows that depths in the study
stations ranged from 20 to 110 m and pH values ranged from 5.73 to 7.92. Water temperature
ranged from 26.3 to 31.13 oC, and was in decreasing trend as depth increased. DO concentrations
at all stations were above 7 mgIL. Chlorophyll-a value was the highest at 20 m depth at station 10
and lowest at sub-surface of station 9. A total of 8 families represented by 17 species of fish were
caught from the reservoir. The most dominant family in tenns of the number of individuals caught
is Cyprinidae. Barbonymus schwanenfeldii is the most dominant species with the highest number of
individuals caught. Length-weight relationship of the three species in the reservoir shows b value
ranging from 2.79 to 2.88 which indicate that the fish has negative allometric growth Gonadal
Somatic Index (GSI) ranged from 1.09 to 3.24. The average fisheries production in the reservoir
range from 17.12 to 20.55 kg ha-1 yr-l. Therefore, proper management of the reservoir should be
done to sustain the fisheries production in Batang Ai Hydroelectric Dam, Sarawak. |
