Abstract
  • Investors in aquaculture are biased against the mangrove areas and prefer to site their farms in the upland parts of Southwest, Nigeria. This study was carried out to compare the yield performance in the two fish farm locations. The tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that despite being capital-intensive, adequate revenue could be realized from farms both in the upland and mangrove areas. While the upland farms yielded an average gross revenue per hectare per year of ₦1,166,308.60, the mangrove farms yielded ₦1,033,263.60 meaning that the difference is slight. The results of the combined cash flow and sensitivity analysis buttressed that of the budgetary analysis. The NPVs were ₦1,382,790.00 and ₦1,317,731.20, the B/Cs were 1.28 and 1.29 and the IRR were 48.55% and 48.51% for the upland and mangrove farms respectively. The profitability ratios were also comparable but slightly higher in the upland fish farms. From all the indices obtained, it can be concluded that there is little or no difference in yield performance in the two farm locations. However, the risk of loss of investment in years of excessive flood by investors operating in mangrove areas should prompt them to insure their farms with the Nigerian Agricultural Insurance Company.
