Aquaponics represents a sustainable and resource-efficient approach to food production, integrating aquaculture and hydroponics into a closed-loop system that recycles nutrients and minimizes waste. This study evaluates the design, operation, and financial feasibility of a small-scale aquaponics model established at the Department of Fisheries and Aquaculture Technology, Federal University of Technology, Akure. The system was designed using locally available materials to assess its practicality for smallholder farmers. Detailed observations were made on system setup, component integration, water management, and crop fish interactions. Economic evaluation considered construction and operational costs, revenue generation, and payback potential. Results indicate that aquaponics supports efficient nutrient utilization, conserves up to 90% of water compared to conventional farming, and reduces input costs through resource recycling. Financial analysis revealed a favourable cost-benefit ratio, demonstrating that small-scale aquaponics can be both economically viable and environmentally sustainable. Beyond profitability, the aquaponics model contributes to food security by enabling year-round production of fish and vegetables in limited spaces. The study concludes that aquaponics offers a practical and scalable solution for sustainable agriculture in Nigeria and similar developing contexts. Wider adoption through training, policy support, and investment incentives is recommended to promote green innovation and improve rural livelihoods.
