This paper analyses economic profitability of improved fish breeding systems in use in the valley of Ouémé, South of Benin Republic. A total of 85 fish breeding unities are sampled in the municipalities of Bonou and Ouinhi, following the method of ‘’ball of snow’’. Data concerned sociodemographic characteristics, types and areas of fishbreedingsystems, the prices and quantities of the inputs used and outputs. Data analysis was based on descriptive statistics of general data, and tests of means comparison (ANOVA) of profitability indicators, such as gross and net margins and rate of profitability. Results showed that there are four types of improved fish breeding systems in use in the study area, such asmonoculture, polyculture, compensatory growthandco-culture. Results showed also that the most profitable improved fish breeding systems are, following decreasing order, compensatory growth, co-culture, polyculture andmonoculture, whatever the profitability indicator that was targeted. On the other hand, feeding fish every 24 hours under experimentation with compensatory growthis revealed as the most profitable fish feeding practice. The compensatory growthis recommended for the better income and food security of fish breeders in valley of Ouémé.
