Gelatinous plankton is important in the diet of European eel (Anguilla anguilla) larvae in the Sargasso Sea
Limited insight into eel larvae feeding and diet prevents a holistic overview of the life-cycle of catadromous eels and an understanding of the ecological position of their early stages in marine waters. The present study evaluated the diet of larval European eel, Anguilla anguilla - a critically en...
