Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. Most of the aquaculture fish farmers are prone to the risk of climate change, since weather and extreme events have become more unpredictable. This study assessed the climate change risk management strategies among the aquaculture fish farmers in southwest Nigeria. Multi-stage sampling technique was used to select 180 aquaculture fish farmers in the study area. Descriptive statistics, likert scale, net profit and multinomial logit model were used to analyze the data. The results revealed that 81.3% of the respondents were within the active productive age in the study area. The study revealed that all the respondents were aware that climate is changing and the most observable climate variable according to the respondents is unpredictable rainfall (72%). Table size fish production was profitable with net profit of 1,057,500 Naira per annum ($2897.26). The commonly used adaptation strategy by the aquaculture fish farmers in the area was use of concrete pond/fiber tank (78%). The result of the multinomial logit model revealed that farm income influences the adoption of flood control/provision of water outlet by 19.22% and provision of alternative water supply (Borehole) by 45.11%. The study recommends that government at all levels should provide credit facilities at a single digit interest rate to mitigate the effects of climate change on aquaculture fish farmers in the study area.
