Abstract: Sewage from aquaculture farms can cause, like domestic and industrial wastewater, surface water pollution. This study aims to characterize, on a physicochemical level, the wastewater emitted by a fish station installed near the Ebrié lagoon. Four seasonal sampling campaigns were conducted between August 2016 and July 2017. Temperature, pH and dissolved oxygen were measured, in-situ, using a multiparameter. Then, a 1 liter glass flask was used to take a sample of water and effluents at the entrance of the station and at the exit of the station, respectively. Analyzes in the laboratory determined the concentrations of nutrient salts, BOD5 and SS. The results reveal that the discharged water is acidic (pH=5.8 ± 0.32), poor in oxygen (2.2 ± 0.13 mg O2/l), has a very high organic matter load (OPI between 1.5 and 2) and a high rate of SS (273.25 ± 57.75 mg/l). This fish wastewater is inadequate to be discharged into the Ebrié lagoon and must therefore be treated before discharge or reuse.
