This study examines whether suction dredging for cockles on tidal flats of the Dutch Wadden Sea had affected densities of non-target fauna, directly after fishing and one year later. Densities of non-target fauna in two randomly chosen undredged locations were compared to densities at the surrounding heavily commercially dredged area. A significant negative effect of cockle dredging on densities of 0-group <i>Macoma balthica</i> was observed and this effect persisted one year after dredging. The dredged area appeared to be less suitable for settlement of mussels <i>Mytilus edulis</i>. No significant effects of dredging on the mudsnail <i>Hydrobia ulvae</i> and on 0 and 1-group <i>C. edule</i> were found. For the mobile young <i>Macoma balthica</i> it seems unlikely that the effect found after one year was still due to the mortality caused by dredging and this suggests that the habitat was less suitable as a consequence of dredging. Thus, even in the highly dynamic ecosystem of the Wadden Sea, effects of bottom disturbance by cockle dredging may persist after one year.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of suction-dredging for cockles on non-target fauna in the Wadden Sea","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"dredging; fishing effects; Cerastoderma edule; Macoma balthica; tidalflats; Wadden sea; the Netherlands","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2003-11-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000186725800005","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.seares.2003.06.002"},"refs":null,"anarec":{"AnaID":55419,"PubliDate":2003,"Pagination":"315-323","XtraPublOfAnaID":null,"ISBN":null,"Volume":"50","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
