Seasonal evolution and individual differences in silvering eels from different locations
Résumé
Here we present new information on the triggers, duration and succession of events up to the silver migratory stage. The transitional stages - between the yellow (resident) stage and the silver (migrating) stage - were characterized through exhaustive sampling of both resident and migratory eels. New aspects concerning the endocrinology of the silvering process will be given based on seasonal sampling of eels undergoing metamorphosis.
