This document presents a comparative assessment of four triannual analyses carried out between 1986 and 1995, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gear used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels Over the period, an average of 11 components have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics (gears, species, vessels characteristics) of each component described are globally stable over the study period, the behaviours of the boats belonging to one or the other groups are far from being stable. Depending on the attraction of the target species and the gears needed for their capture, boats have been found to move from one component to another. From this study, it is possible to conclude that the inshore polyvalent boats have been the most able to support the modifications undergone by the fishery over this ten year period. Among the whole of the components, gillneters have registered the strongest progression
