"{A}cadja-enclos" is an extensive aquaculture system where #{S}arotherodon melanotheron$ (#{C}ichlidae$), a herbivorous fish, occurs mostly. {O}rganic charge and periphytic concentrations (chl a, pheopigment, total pigments) were determined on each sample (from different locations). {S}pecific microalgae composition and light intensity were also estimated. {T}he periphytic community within the "acadja" was mainly composed of filamentous algae with #{R}hizoclonium$ ({K}utzing) (#{C}hlorophyceae$) as the major genus. {C}yanobacteria and many species of the diatom #{N}itzschia$ comprised a high proportion of the epiphytes found.
