Difference in factors explaining growth rate variability in European eel subpopulations: the possible role of habitat carrying capacity
This study was funded by the 'Region Bretagne', the MAVA Foundation and 'Bretagne Grands Migrateurs'. The surveys and sampling were organised and operated by the company FISH PASS and the association 'Coeur Emeraude' in the Fremur River, and the INRA-Rennes and ONEMA in...
