The study focused on the comparative evaluation of economic benefits of earthen fish ponds and concrete tanks in aquaculture enterprises in Ibadan, Oyo state. Primary data were collected with the aid of structured interview schedule, administered through personal interviews and obser- vations to elicit information from 100 fish farmers using purposive and convenience sampling procedure. Data collected were analyzed using descriptive, budgetary and inferential statistics. The study revealed that the mean age, male, married, household size, educated and fish farm- ing experience were 41 years, 83.0%, 87.0%, 5 persons, 96.0% and 8 years, respectively. Earthen fish ponds users earned mean revenue of ₦3,322,189.85 with gross margin of ₦2,188,397.89 while concrete tank users earned ₦2,412,271.08 with gross margin of ₦1,413,299.46. The results showed profitability indices (0.61 and 0.47), Variable Cost ratio (0.35 and 0.30), Benefit Cost Ratio (2.55 and 1.89), Gross ratio (0.40 and 0.54) and Expenses structure ratio (0.13 and 0.23) for both the earthen ponds and concrete fish tanks, respectively. There were significant differences (t = 42.53, p≤0.05) between the profit level of earthen fish ponds and con- crete tanks. Major constraints affecting economic status of the respond- ents were high cost of quality feed, insufficient funds, poaching and poor marketing channel. In conclusion, aquaculture is a more profitable and vi- able business regardless of the culture system. Government should assist the fish farmers by subsidizing feeds cost, granting and monitoring of loan. © The Author(s) 2014. Published by University of Zagreb, Faculty of Agriculture.
