The objective of the study is to describe fisheries of freshwater shrimp or “black shrimps” or crayfish” Macrobrachium vollenhovenii, Macrobrachium macrobrachion catches in Ivorian lagoons; Sassandra and Comoe rivers from 2007 to 2009. In this context, interviews with fishermen were conducted to characterize them and their activities. Landing catches were followed monthly from 2007 to 2009 at the dock of Sassandra for Sassandra River, Fresco village for Fresco lagoon, Lahou Pkanda for Grand-lahou lagoon, Grand Bassam for Comoe river and Adiaké for Aby lagoon. The results of the works showed that the total catch of fresh water shrimps were low (12 tons in 2009) compared to pink shrimp Penaeus notialis catches in lagoons (400 to 500 tons per year for all lagoons). However, with high market value price per kilogram between 600 and 2000 FCFA, the fisherman of freshwater shrimps receives a net monthly income that enables him to be classified according to the indicators of the Strategy Paper on Poverty Reduction (PRSP) among people who are not poor. However, with the pressure of fishing on these resources, the fisheries management authority shall take measures for sustainable management of shrimp and especially to initiate the culture of crayfish to contribute to the sustainability of fisheries and the resource.
