Status of Reservoir Fisheries in Batang Ai Hydroelectric Dam, Sri Aman, Sarawak

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 station...

Fisheries. Angling 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.
