During spawning migration, the movement of freshwater resident eels from river to sea has been thought to be irreversible. We report the first recorded incidents of eels returning to the river of origin after spending up to a year in the marine environment. After migrating to the Baltic Sea, 21% of the silver eels, tagged with acoustic transmitters, returned to the Narva River. Half returned 11–12 months after moving to the sea, with 15 km being the longest upstream movement. The returned eels spent up to 33 days in the river and migrated to the sea again. The fastest specimen migrated to the outlet of the Baltic Sea in 68 days after the second start—roughly 1300 km. The surprising occurrence of returning migrants has implications for sustainable management and protection of this critically endangered species.","AbstractOtherLang":"behavioural diversity, conservation strategy,European eel, ","BibLvlCode":"AS","StandardTitle":"Migrating silver eels return from the sea to the river of origin after a false start","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"behavioural diversity, conservation strategy, European eel","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-09-09","DateCreate":"2021-09-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000693570700003","VABBcode":null,"OpenAcc":0,"DOI":"10.1098/rsbl.2021.0346"},"refs":null,"anarec":{"AnaID":344574,"PubliDate":2021,"Pagination":"20210346","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":264506,"SerRR":"Biological Letters: Poznan.
