| Abstract |
Chapter one presents the characteristics of the glass eel fisheries in the Bay of Biscay. Chapter two analyses in detail the fluctuations of glass eel catches in the basin of Adour. Chapter four proposes a modelling of hydro-climatic condtions on the variability of the glass eel catches. Chapter five presents two approaches for estimating the biomass, using a sampling protocol of the glass eel run based on a behavioural model. Chapter six deals with the development of mono and two-dimensional hydrodynamic models. Chapter seven describes the intensity of colonization and the variations of yellow eel densities on the catchment area of the Adour river and Gaves. Prospects for this work are evoked; they are related to the valorization and the transfer of knowledge towards the managers within both the framework of the ICES and the framework of the INTERREGIII program. The development of this work should also include the problem of the impact of contaminants and degradation of eel habitats on the future of this resource. |
