Abstract: This research was initiated to study the impacts of climate variability on the production of fish holes in the lower Ouémé valley.To achieve this objective, the analysis of the climatological data from the period 1986 to 2015, extracted from the ASECNA files using the parameters of the descriptive statistics allowed to characterize the evolution of the climate, Water and flow data extracted from the DG-Eau files and then the fish statistics obtained from the Fisheries Directorate made it possible to analyze the evolution of fish hatchery yields in the study environment. The SPSS software was used to show the correlations between the evolution of climatic parameters and the production of fish holes with the correlation text of the Pearson correlation at a threshold of 5%.Analyzes show that changes in fish yields are positively correlated with rainfall, while there is a negative correlation between fishery yields and thermal management.
