Implication

Environmental and economic assessment reveals profitable yields alongside severe water pollution in lake tilapia farming, suggesting aquaculture expansion must be halted.

Key Points

Evaluate the financial feasibility of tilapia (Oreochromis niloticus) aquaculture using floating net cages and assess the carrying capacity and water quality of the lake ecosystem.
Surveyed 30 tilapia fish farmers across the three villages with the highest concentration of floating net cages to calculate discounted investment parameters.
Collected six deep-water samples across three lake sampling locations to evaluate physical and chemical water quality indicators.
Tilapia cage farming proved financially feasible, yielding a positive Net Present Value, an Internal Rate of Return exceeding 9%, and a Net Benefit-Cost Ratio greater than one.
Water chemistry parameters—including total dissolved solids, nitrite, biochemical oxygen demand, total phosphorus, ammonia, and phosphate—exceeded national Class II water quality regulatory limits.
