Biochemical and genetic characterization of European silver eels, Anguilla anguilla (Linnaeus, 1758), from the Comacchio lagoon (Italy)
Summary: The European eel Anguilla anguilla has declined significantly over recent decades, exceeding its safe biological limits and probably reaching a historical minimum (1% of the 1960 recruitment level). Twenty-three migrating females at the IV stage of silvering were collected from the Comacchi...
