This paper analyzed the effect of flood and socio-economic problems on fish farming in Ibadan Metropolis, Oyo State, Nigeria. A multistage random sampling technique was used to select 80 fish farmers in the state. Both primary and secondary data were collected and analyzed using descriptive statistics to analyze the socio-economic characteristics of the fish farmers, cost and returns analysis was done to determine the profitability ratios of the fish farming in the study areas. The mean age analyzed was 45%. The result of the cost and returns analysis showed that Average Total Cost CATC） of N1, 500,517.5 was incurred, Total Revenue （TR） of N, 138,659,400 was realized and a returning Gross Margin （GM） of N was 64,885,800 by fish farmers. The major constraints encountered by fish farmers were flooding that wash away fish, deposit heavy metals such as ammonia （NH4）, lead, copper, cadmium, arsenic, etc., that can result to the death of fish in the fishponds and rivers when flood overflowing. The methodology applied for the flood examination includes site visits, interviews of affected fish farmers, and analyses of flood data collected during the field examination.
