The effect of thermal shock during diel vertical migration on the energy required for oceanic migration of the European silver eel
International audience Recently, diel vertical migration (DVM) was observed in European silver eels (Anguilla anguilla) migrating towards the Sargasso Sea. However, because European silver eels do not feed during this migration, their energy consumption requires accurate optimization due to their li...
