With broad distributions, diadromous fishes can be exposed to multiple threats at different
stages of development. For the primarily catadromous eels of the family Anguillidae, there is …

Anguillid eels are found globally in fresh, transitional and saline waters and have played an
important role in human life for centuries. The population status of several species is now of …

The spawning migration of the European eel (Anguilla anguilla L.) to the Sargasso Sea is
one of the greatest animal migrations. However, the duration and route of the migration …

Other Anguilla species have occasionally been stocked in Europe, but none have
