The silvering process of Anguilla anguilla: a new classification from the yellow resident to the silver migrating stage
The identification of five stages for female and two stages for male eels Anguilla anguilla using multivariate analysis was carried out on a large sample of individuals collected at six different locations in France. Stages corresponded to a growth phase (stages I and II), a pre‐migrant phase (III)...
