This study aims at assessing the production of Clarias gariepinus and Oreochromis niloticus reared for 120 days in cages and pens installed in the Batran water reservoir in the cotton basin and Songhaï water reservoir outside the cotton basin in northern Benin. For C. gariepinus, the final biomass and the production values are significantly higher in Batran-caged fish while the lowest values are obtained with the same infrastructure in Songhaï. Differences are significant between the two infrastructures only in Batran. With regard to O. niloticus, values obtained for these two parameters are about twice as high in Songhaï compared to Batran in both cages and pens. They are similar between the two infrastructures in each water reservoir. However, cages that do not promote fish contact with aquatic sediment would be more appropriate to avoid the health risks associated with agricultural pesticides in the water reservoir located at the cotton basin.
