Eel parasite diversity and intermediate host abundance in the River Rhine, Germany
European eels ( Anguilla anguilla ) from 2 sampling sites on the Rhine river (near Karlsruhe and near Worms) were investigated with respect to their parasite communities. Nine different metazoan species were found to live in and on the eels. The highest number of species was recorded from the intest...
