Therefore, internal implantation of electronic tags, such as acoustic, radio and data storage tags is challenging. Preliminary tests are conducted to assess the impact of external tagging on twaite shad survival in Belgium.  Fish were caught in the Zeeschelde, with two mid-water beam trawls from an anchored boat in spring 2015, 2016 and 2017 and 39 shads were tagged in total, with coded acoustic transmitters from Vemco. Beside an evaluation of the taggin technique, the data give valuable insights into the migration behaviour of twaite shad in the Scheldt estuary and in the North Sea directly after downstream migation. The dataset will be extended and analysed further in the coming years.","EngDescr":"Although twaite shad (Alosa fallax Lacépède 1803) declined substantially in many European rivers, its numbers increased since 2007 in the Belgian Zeeschelde. Since twaite shad is of conservation concern (Habitat directive), further knowledge on its migration and reproductive behaviour is needed and acoustic telemetry would be a relevant tool to assess these behaviours.","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":null,"OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":null,"AccessConstraints":null,"UDate":"2018-01-03","CDate":"2018-01-03","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-14 01:44:00.153333","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":0,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":1,"FreshFlag":0,"BrackishFlag":0,"TerrestrialFlag":0,"StatusID":1,"DasType":"Data","DasTypeID":1,"DasOrigin":"Sensor platform","Progress":"In Progress","AccessConstraint":"Unrestricted after moratorium period","AccConstrEN":"Unrestricted after moratorium period","AccConstrDisplay":null,"License":null,"AccConstrDescription":"Data are initially restricted, but the access condition relaxes to academic or unrestricted once a specified period of time after an event (such as collection, publication, completion of QC procedures or project cessation) has elapsed","Lineage":null,"AccConID":8},"dois":null,"spcols":[{"SpColID":131,"SpName":"Belgian marine datasets"}],"keywords":[{"ThesaurusTerm":"Acoustic telemetry","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_3563933f","Description":null,"OrigThesTerm":"Acoustic telemetry","DutchTerm":null,"URI":"http://aims.fao.org/aos/agrovoc/c_3563933f","DasKeywordDescr":null},{"ThesaurusTerm":"ANE, North Sea","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, North Sea","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Belgium, Upper Sea Scheldt","ThesTypID":35,"ThesType":"Geoterms no link Marine Regions","Code":null,"Description":null,"OrigThesTerm":"Belgium, Upper Sea Scheldt","DutchTerm":"Boven Zeeschelde","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"External tagging","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"External tagging","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Fish migration","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Fish migration","DutchTerm":"Vismigratie","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Fish movement","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Fish movement","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Spawning migrations","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_4d1412b7","Description":null,"OrigThesTerm":"Spawning migrations","DutchTerm":"Paaimigraties","URI":"http://aims.fao.org/aos/agrovoc/c_4d1412b7","DasKeywordDescr":null},{"ThesaurusTerm":"Tidal estuary","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Tidal estuary","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Tracking data","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Tracking data","DutchTerm":null,"URI":null,"DasKeywordDescr":null}],"parents":[{"DasID":5250,"Acronym":null,"EngAbstract":"As part of the Belgian LifeWatch observatory, a permanent acoustic receiver network for fish tracking is established in the Belgian Part of the North Sea and the Western Scheldt.

When swimming in the vicinity of an acoustic receiver (Vemco), the information of the unique ID-code of the transmitter is stored on the receiver together with an exact timing of the event. When signals are simultaneously received by multiple receivers, an exact positioning of the tagged individuals can be derived from the raw data.
