A comparative study of eel (Anguilla anguilla (L.)) population structure in three sites in Italy, and preliminary considerations on the relative contribution to escapement.
Eel population structure has been evaluated in three sites, (river Tiber, Caprolace and Lesina lagoons) in Italy, within a project aimed at the setting up of a integrated approach to the eel conservation and management in the Mediterranean area. First results show both differences and similarities b...
