Survey of Aquaculture Investment Patterns and Profitability among Commercial Fish Farmers in Oyo State

Commercial fish farming has become an increasingly popular investment vehicle for urban entrepreneurs in South West Nigeria, yet data on actual investment patterns, production costs, and profitability at the farm level in Oyo State remain scattered. This study surveys 100 registered commercial fish farmers in Ibadan, Oyo State, documenting initial capital investment, production costs, output, revenue, and profitability indicators through structured questionnaires and financial record analysis. Farms were categorised by scale into micro (below 500 fish capacity), small (500 to 2,000), and medium (2,000 to 10,000) operations. Results showed that feed costs constituted the largest share of production expenditure (62%), followed by fingerlings (14%) and labour (11%). Return on investment was positive for 73% of respondents, with medium-scale farms recording higher and more consistent profitability than micro farms. Gross margin per kilogram of fish produced ranged from 210 to 680 Naira depending on production scale and market channel. Farmers selling directly to consumers or through farm gate markets achieved significantly higher gross margins than those selling to middlemen. Access to credit was identified as the primary constraint to scaling operations by 68% of respondents. The study provides empirical financial benchmarks for aquaculture investment in Oyo State and recommends the inclusion of aquaculture enterprise development in the Oyo State Government's agricultural investment promotion framework.
