Abstract
The genus Anguilla is worldwide distributed. Part of humanity’s heritage, it represents a resource of proteins for many people. Most stages of the species within the genus Anguilla have experienced a drastic decrease of their abundance since at least the middle of the twentieth century. It is the case for European eel (Anguilla Anguilla) largely impacted by the climate change. To restore the population, an European Eel Management Plan has been implemented in 2010: fishery regulation, restocking, improvement of eel habitats, the first effects of which are expected to have improved eel abundance from 2013. Are we able to detect that such an increase has occured in the centre of the eel distribution area (north of the Iberian Peninsula, Gulf of Biscay)? Are the different potential management actions defined in the Eel Management Plan implemented? What are the necessary improvements to restore the eel population in Europe?

This size is a size limit for the young individuals newly recruited that begin the process of the catchment colonization.

That size category corresponds to older individuals aged 2–5.

Tidal limit: the maximum upstream location at which a tidal variation of water level is observed.
- 15.
D0.5 limit: which corresponds to the distance from the tidal limit where the probability of observing eels less than 30 cm is equal to 0.5. It is a colonisation and accessibility index.
