Being almost in the middle of the Atlantic Ocean and consisting of an archipelago of volcanic islands with small streams running dry during periods of low to no precipitation, it is a unique system across the European-wide habitat range for European eels. In fact, it is the only native teleost inhabiting the freshwater systems on the Azores. As the species is considered a symbol for global change, knowledge on its ecology can be used to assess human impact on aquatic systems. In this project, we track the silver eels in a stream during their migration to the sea. ","EngDescr":"This can lead to insights on timing, migration speed and potential hazards (e.g. waterfalls) they need to take. Obviously, the results will contribute to a cost-effective management of the streams on the Azores and the conservation of the critically endangered European eel.","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":"2026-11-30","OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":null,"DescrTransFlag":null,"Citation":"Afonso P., Verhelst P., Priester R., Reubens J. 2022.
