Floating net cages have become important in the last decade and it has been supported and encouraged by Sarawak State Government. There is no such a carrying capacity study has been done at Batang Ai Reservoir. Therefore, estimating the reservoir’s carrying capacity due to fish farming culture activities was an important tool for making environmentally related decisions prior to any potential negative impacts. Numerical computer analysis was used to simulate the initial average concentration of total Phosphorus (TP) in the reservoir. The computed TP result was applied into the empirical models to estimate the fish productions carrying capacity for Batang Ai reservoir, which was referred to allowable TP of 0.035 mg L−1 as recommended by Category C, Malaysia National Lake Water Quality Standard. The carrying capacity for the reservoir was estimated at 4,239 tonnes per year, which was approximately five times higher than the present fish productions level as reported by local published journals. Thus, it can be concluded that future expansion of fish production in Batang Ai reservoir is still feasible. |
