The fishing activities are nowadays practised by the surrounding populations of the valleys, lakes, lagoons, the sea and other aquatic ecosystems, sources of the fish species that man needs. The objective of this research is to analyze the current fishing units and systems in the Porto-Novo lagoon. To do this, data on the socio-economic characteristics of fishermen, the different gears and fishing units were collected in order to analyze the determining factors. The study was conducted in Porto-Novo, a total of 200 fishermen on the lagoon were randomly sampled and then interviewed. Generally speaking, fishing activities in the Porto-Novo lagoon are practised by men and women, mostly in couples (93%). They are mainly Goun (42%), (35%), Toffin (19%). Thirteen (13) fishing gears (hawk net, sleeping net, Thion, trailing fishing net, fixed net avê, Crab scale trap, Fish traps, Shrimp traps, baited longlines, unbaited longlines, Mêdokpokonou, Lines and Scoops) exist on the lagoon with a preference for the hawk net (25%), the sleeping net (19%), the fish traps (16%) and the trailing net (13%). The fishing units are categorized into six (06) groups introduced into the multivariate regression model. This model reveals that the use of fishing units depends on the socioeconomic characteristics of fishermen.
