This research work was conducted to investigate the economic returns of fish farmers in Osun State. A multi-stage sampling technique was employed in administering a combined open and closed- ended questionnaire. Data were collected on various socio-economic characteristics affecting farmers’ output which include: sex, age, farming experience, level of education, household size, nature of involvement, etc. The data were analyzed using analytical tools like descriptive statistics, budgetary analysis and regression analysis. The descriptive statistics covers socioeconomic characteristics of the respondents assessed using frequency distribution tables. The budgetary analysis shows higher revenue to large, medium and small- scale farmers in that order. The regression analysis made use of seven independent variables to capture their effect on fish output. Four functional forms viz linear, semi- log, double log and exponential functions were fitted. The effects of the variables are best seen to be measured and explained by the linear function. Resource use efficiency indicates that all the variables are under- utilized except for lime and fertilizer that were over utilized. The study highlights some problems facing the business such as: poaching, expensive feed cost, scarcity/ high cost of fingerlings as well as seasonality of water. Co-operative organization, awareness creation, integrated fish farming, organizing seminars/conferences/workshops, subsidy on major inputs and farm hygiene was recommended.
