Abstract

An halieutic data collection system was established in 2007 in Guadeloupe. The objective of this one is to apprehend the whole of the fishery through these various components as biological, economical or technical. The data collection at the landings, one of the applications of this system inform about the composition of the captures. In this work, we interested in the metier being practiced on the insular shelf of Guadeloupe and in particular with the metier of the trap and the fixed gill net. These two metiers more practised by the fishermen are studied through the landing’s data in order to bring first elements as the structure and the level of exploitation of the populations on the insular shelf. After having specified and characterized classes of landing for each metier, we compare the exploited trophic levels. Finally we identify the influence of the spatial and temporal variables on the modeling of the CPUE. The results show that three classes arise and have similarities between the two metiers. We observe these two metiers target at the same time populations of herbivores on low depths area but also populations of higher trophic levels present in more important depths. It is also noted that the gradient of depth appears as a relevant indicator for the characterization of profiles of capture like for the modeling of the CPUE.
