The infection of the European eel with the parasitic nematodeAnguillicoloides crassusin inland and coastal waters of northern Germany
Recruitment of the European eel is in decline since three decades. So far, the reasons of the decline have not been fully understood. Beside other factors, infection with the exotic swimbladder parasite Anguillicoloides crassus has been discussed as a threat to the species. In the present study moni...

Recruitment of the European eel is in decline since three decades. So far, the reasons of the decline have not been fully understood. Beside other factors, infection with the exotic swimbladder parasite Anguillicoloides crassus has been discussed as a threat to the species. In the present study monitoring results for A. crassus in eels from North German waters are presented. Between 1996 and 2011, the swimbladders of 17,219 eels from eight freshwater and coastal water areas were analyzed. Prevalence, abundance of parasites, infection intensity and severity of the damage to the swimbladder were recorded by visual inspection.
