Monitoring of parasite and virus infections of the European eel, Anguilla anguilla, in northern Germany
The aim of this thesis was to examine metazoan parasite communities and viral infections of European eel, Anguilla anguilla, from fresh water, brackish and marine localities in northern Germany. The here collected data shall help to evaluate the suitability of the studied localities for potential re...
