La recherche scientifique face Ă la pĂȘche artisanale = Research and small-scale fisheries
The artisanal and industrial fisheries exploiting demersal resources off the coast of Senegal compete with one another and overlap on the fishing grounds and in the market. The competition occurs in terms of fish species and fish length and in volume and the quality of the catches. On the other hand, there is a complementary in the methods of exploiting the resources by the means of contracts and mutual aid between the two fisheries, and in the financing of the artisanal fishery and the marketing of products. A multidisciplinary approach used to analyse these interactions and involving biological, economic, social and political aspects is described. (Résumé d'auteur
La recherche scientifique face Ă la pĂȘche artisanale = Research and small-scale fisheries
A survey system used in Senegal to obtain data on small-scale fishing activity and results since the start of the 1970s is described. Several situations and solution relating to regional characteristics are presented, within the general context of a stratified plan, with several levels of observations in each stratum. Certain procedures used to evaluate the qualities of the system are presented and the existence of a sharing of effort between the various species is demonstrated. (Résumé d'auteur
