The lagoon of Porto-Novo is located in the south of the Republic of Benin where rainfall is appreciable. This river, has a high importance for the resident population because of itshalieutic resources providing and its use for domestic activities. This research aim to study a part of the ionic profile of the lagoon to determine what kind of chemical matters it contains. The results show globally composition matching the standards of surface waters. As examples, all of the tenorsregistred are below2000 µS/cm consideredas maximum value for conductivity. Values recorded are alsobelow standards for nitrogenreduced and oxidedforms (NH4+ and NO3-). Samely the PO4- contents are between (0.13 mg/L and 0.22 mg/L, those of iron,between0.31mg/L and 0.44 mg/L and allarebelow standards. These values justifywhy the lagoonprovidesuitable live conditions for halieuticsspecies.
