The hypothesis was that the impact on <i>L. conchilega</i> would be minimal, but that the fauna benefiting from the biogenically structured habitat would be impacted by beam-trawling. In this study, the impact of beam-trawl passage on intertidal <i>L. conchilega</i> reefs and its associated fauna was quantified. A treatment zone was exposed to a one-off experimental trawling. Subsequently, the impact on and recovery of the associated fauna was investigated for a period of 9 days post-impact. Community analysis showed a clear impact followed by a relatively quick recovery as apparent through MDS analysis (stress 0.06), a significant (<i>p</i> < 0.001) IMS of 0.61, through ANOSIM analysis: significant (<i>p</i> = 0.001) dissimilarities between treatment and control and through SIMPER analysis (decreasing dissimilarities over time). This impact and subsequent recovery was largely explained by two species: <i>Eumida sanguinea</i> and <i>Urothoe poseidonis</i>. Species analysis confirmed the beam-trawl passage significantly (<i>p</i> = 0.001) impacted <i>E. sanguinea</i> for the whole period of the experiment. The experiment confirmed that closely associated species of <i>L. conchilega</i> reefs are impacted by beam-trawl fisheries. This small-scale intertidal study provides some pointers which indicate that the tightly associated species will be impacted significantly when beam-trawling <i>L. conchilega</i> reefs in subtidal areas.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Experimental beam-trawling in <i>Lanice conchilega</i> reefs: impact on the associated fauna","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":"beam-trawl disturbance; associated fauna; Lanice conchilega; Eumida sanguinea; GLMM","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2018-07-19","DateCreate":"2010-01-11","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":143023,"PubliDate":2009,"Pagination":"91-107","XtraPublOfAnaID":null,"ISBN":"978-90-8756-025-6","Volume":null,"Issue":null,"BRefMon":143014,"BRefMonRR":"<b>Rabaut, M.</b> (2009). <i>Lanice conchilega</i>, fisheries and marine conservation: Towards an ecosystem approach to marine management.
