In the absence of effective fish passage systems, the current level of river connectivity is insufficient to support upstream movement and migration for this diverse, multispecies fish community. The tagged cyprinids displayed evidence of migratory behaviour. Individuals of vimba bream, barbel, asp and common nase that were transported across the lowermost dam and released into the lower reservoir section showed rapid upstream movement, suggesting that the reservoir itself did not present significant obstacles to migration. Some covered the entire 76\u2010km long reservoir within a few days to 2\u2009weeks but were ultimately blocked by the next dam. Cyprinids released below the dams were recorded at varying depths and on both sides of the river. Asp, barbel, common nase and vimba bream moved both upstream and downstream relatively close to the surface below the Iron Gate II dam, averaging 2\u20133\u2009m below the surface, but also diving down to about 10\u201320\u2009m. Future studies combining three\u2010dimensional telemetry methods and detailed information on hydrology below the dams could provide further information on the behaviours of the different fish species, which is needed to design efficient fish passage solutions.\n                  <\/jats:p>","DOI":"10.1111\/jfb.70204","type":"journal-article","created":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T01:43:59Z","timestamp":1756950239000},"page":"2056-2066","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Preliminary insights into fish movements beyond the massive Iron Gate dams on the Danube River using acoustic telemetry"],"prefix":"10.1111","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4346-1432","authenticated-orcid":false,"given":"Marija","family":"Smederevac\u2010Lali\u0107","sequence":"first","affiliation":[{"name":"University of Belgrade, Institute for Multidisciplinary Research  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Paraschiv","sequence":"additional","affiliation":[{"name":"Danube Delta National Institute for Research and Development  Tulcea Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gor\u010din","family":"Cvijanovi\u0107","sequence":"additional","affiliation":[{"name":"University of Belgrade, Institute for Multidisciplinary Research  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torgeir B.","family":"Havn","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research  Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Hont","sequence":"additional","affiliation":[{"name":"Danube Delta National Institute for Research and Development  Tulcea Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirjana","family":"Lenhardt","sequence":"additional","affiliation":[{"name":"University of Belgrade, Institute for Multidisciplinary Research  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Iani","sequence":"additional","affiliation":[{"name":"Danube Delta National Institute for Research and Development  Tulcea Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert J.","family":"Lennox","sequence":"additional","affiliation":[{"name":"Ocean Tracking Network, Department of Biology Dalhousie University  Halifax Nova Scotia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Du\u0161an","family":"Nikoli\u0107","sequence":"additional","affiliation":[{"name":"University of Belgrade, Institute for Multidisciplinary Research  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Finn","family":"\u00d8kland","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research  Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel A.","family":"Paterson","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research  Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva B.","family":"Thorstad","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research  Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"Baji\u0107 A. \u0411\u0430\u0458\u0438\u045b \u0410.
