This study carried out on the lagoon near Abobodoumé has the aim to map the fishing areas of the fish. The main question is : what is each fishing area identified by the fishermen ? the results obtained show that the fishermen fish in this locality are all foreigners, Ghanaians, Beninese and Nigerians living in perfect harmony. The fishing areas are in part the result of the techniques of the players, the gear they use and the fishing seasons. But there is also the influence of the anthropogenic pollution, dredge the sea sand and the proximity of the port area. In order to obtain the above-mentioned results, a methodology that consisted of a literature search and on the internet, but also the research of primary data was the need to go out into the field. Specifically, we have, with the help of an interview guide interviewed the actors of the fishery. At times, we have used instruments for measuring gear such as canoes and nets. We also exchanged with the port authorities and agencies in charge of monitoring the water quality.
