A study of the Ouémé River fisheries carried out between 1999 and 2001 recorded some 13 fishing gears and capture methods. Gillnets and traps are the most used gear in the north, whereas the fishing equipment in the southern stations is more diverse, with many variants, each tailored to specific needs (exploited biotope, target species, hydrologic seasons). High fishing pressure is exerted on resources in the south and yield of some fishing gears is in decline: 2.2 kg of catch per day for the gillnets, 3.5 kg for “dobah” and 1.4 kg of catch for castnet versus respectively, 5.2 kg, 4.3 kg, and 1.6 kg recorded in the Ouémé delta during 1968 and 1969. The specific composition of catches has considerably changed and now characterized by dominance of small fishes. Large spacies such as Heterobranchus longifilis, Chrysichthys nigrodigitatus, Gymnarchus niloticus and Lates niloticus, formerly abundant in the catches, have now become very rare. In order to better understand the general ecology of the river and is hydrologic regime and to estimate total fish production, a complementary study is nesccessay. This prerequisite for a good and sustainable management plan. [less ▲]
