Pêcheries bigoudenes. Bilan des connaissances Activités de pêche, Ressources, Gestion ArchiMer
Biseau, Alain; Maguer, Cedric; Sanz Aparicio, Céline.
Located at the far south-west of Brittany, the pays bigouden is the first of the French maritime regions in terms of landed value and the second one in weights. The bigouden fishing practices are characterised by a large diversity of target species and métiers. Studying the fishing practises leads to a description of the various métiers and fishing strategies together with their trends over the last ten years. Identification of métiers is based on multifactors analysis. Using a classification method based on thresholds of species landings then allows a more objective analysis and leads to a more quantitative characterisation of the trawl métiers, which represent more than 80% of the total fishing activity of this region. Two métiers are based on Nephrops...

Problématique de suivi de la pêche insulaire ArchiMer
Reynal, Lionel; Maguer, Cedric; Taquet, Marc.
Insular fisheries statistics are often insufficient to allow a good management of halieutics resources. The reasons of this insufficiency, in large part, is due to inadequate methods for recording catch data and analyzing fishing effort. This presentation proposes the use of a software pro gram (<< S.P.1. ») which helps to elaborate statistics from sampling, making easier the work of personnel who are charged with producing encoded informations on insular fisheries

Typologie de l'activité de Pêche en Guadeloupe ArchiMer
Maguer, Cedric; Reynal, Lionel; Taquet, Marc.
This work aims to describe fishing activity in Guadeloupe through a typology. The samply unit y is the landing represented by a profile of specific composition. Using multivariate analysis methods allows to synthesize this fishing multi specises and multi fishing tackles. Principal Component Analysis and classification regroup landings. Then, segmentation method separateses classes by species composition. Typology is obtained by association of classes and tackles. The contraist between landings of reef fishes realized with traps and those which search for pelagics is clearly shown. Landings of queen conch and landings without fishes are separated in two classes.
