  abstract = {{A}nalysis of artisanal fisheries in developing countries is often confronted with the complete lack of knowledge of both the resource and the fishery. {T}hese problems facing scientists therefore seem unsurmountable : biotope heterogeneity, resource variability, diversity of fishing practices, large number of landing sites and the large area to be covered. {T}he solution adopted in the {N}iger {C}entral {D}elta, to obtain the data necessary for the definition of efficient sampling strategy in the shortest time, consisted of a preliminary multidisciplinary survey carried out at two typical times of the year : flood and low water. {T}he statistical conception of the study is presented, together with results obtained in areas such as the type of fishermen and settlements, plus a stratification of the {D}elta into homogenous zones. {T}hese results should allow the adoption of a sampling scheme structured on a multi-dimensional stratification, likely to increase the efficiency and cost-benefit of future investigations.
