The exploitation of amphihaline species by marine and freshwater commercial fishermen in the Loire estuary in 1989, and by marine commercial fishermen in the Adour estuary from 1985-1991 is described in this study. This fishery employs 320 fishermen and represents a commercial value of 38 million FF. This is mainly due to the exploitation of glass eel, especially in the Loire River, the landings of which have decreased alarmingly. In the Adour River, the diversity of the exploited species and the total commercial value of drift gillnet catches - on the average 43% - in this fishery are high. The landings of migratory salmonid species are high and they may attain 25% of the total commercial value. This study emphasizes the uniqueness, the socio-economic...

Recherche des marqueurs d'exposition aux contaminants et de fréquentation des habitats chez l'anguille Anguilla anguilla de l'estuaire de l'Adour : de la réponse moléculaire à la microchimie de l'otolithe

Autores: Tabouret, Helene.
In a context of decline of European eel (Anguilla anguilla L.) and search for biological markers of habitat use and quality, a multidisciplinary approach was engaged on the Adour estuary and its associated wetlands. Two axes were developed. The first axe aimed at highlighting the successive presence of the species in different ecosystems based on the otolith elemental composition. The second aimed at the evaluation of the chemical pressure underwent by eels based on the contaminant bioconcentration in soft tissues and the early molecular response to the chemical stress. With a view to the analyses of otolith elemental composition taking into account the 3D structure, the low elemental concentration in the matrix and keeping the finest spatial resolution,...
