| Summary: | No abstracts are to be cited without prior reference to the author.The continuous and steady decline in glass eel (Anguilla anguilla, L.) recruitment and more generally in the eel stock has risen the ICES concern about the status of the eel stock. The European commission pointed out the need to develop management plans at the water district level and for all stages. We developed a Glass Eel Model to Assess Compliance (GEMAC) with eel recovery objectives. In this study we briefly describe this model already presented in working group on eel (ICES, 2005) and as part of the SLIME project. Then, we apply it on the two well documented Vilaine and Garonne basins, which have contrasted anthropogenic pressures. The model allows to assess the proportion of settled glass eels relative to unimpacted conditions (%S/R). A sensitivity analysis of the model is done showing that the assessment of %S/R is quite accurate. The %S/R is estimated to 0.19 for the Vilaine basin and to 0.78 for the Garonne basin reflecting a ... |
