It consists of benthic invertebrates, undersize commercial and non-commercial fishes. Benthic invertebrates are organisms which live on, and or close to the surface of the seafloor. As such they are caught by most trawl fisheries where they constitute a greater proportion of the discards. Gear technology is gaining grounds in limiting discards of some species of benthic invertebrates, commercial fishes <MLS (minimum landing size) and non-commercial fishes. Modified gears like the T90 codend, Benthos Release Panel (BRP), Benthic Barrier (BB) and Square Mesh codend (SMC) have been implemented in experimental trials to test their efficiency and ability to limit discards in the Southern part of the North Sea on the <i>Belgica</i> (research vessel) and <i>Pascin N58</i> (commercial vessel). Sea trials show that T90 outperforms in reducing discards of round fish. Benthic barrier and 200mm BRP significantly reduces the catch of some benthos like <i>Pagurus, Asterias rubens</i> and <i>Buccinum undatum</i>. Benthic barrier was efficient at minimizing the catch of flatfishes <MLS. Furthermore, combination of BRP and T90 codend were detrimental to round fish (whiting) due to high retention <MLS. As a result the implementation of gear technology could lead to discard reduction and stock building for benthic invertebrates and fishes in the North Sea.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"The potential of gear modifications to reduce discards of beam trawl in the southern North 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":"Discards; Benthic invertebrates; Commercial fishes; Standard trawl; Experimental trawl","OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2012,"DateUpdate":"2021-06-09","DateCreate":"2012-09-07","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":217993,"ISBN":null,"PubliDate":2012,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"66","Place":"Brussel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":217993,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":66},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Gorim","Firstname":"Dora Acham","Initials":"D.A.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":209736,"AutID":151223,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":null,"PersID":null,"InsID":null}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":238096,"LibID":36,"BRefID":217993,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"238096","RFID":null,"PaidValue":null,"Medium":"Server","Description":"Interne VLIZ documenten","Acronym":"VLIZ","Library":"Vlaams Instituut voor de Zee","DutchTerm":"Non-open access","URL":null,"ClassifID":228,"Classification":"Non-open access","ReqLink":1,"ClassifTypID":3,"URLLocation":"https://www.vliz.be/imisdocs/publications/","SubDir":1,"InternalReq":1,"LoggedInReq":1,"Disclaimer":"Disclaimer_VLIZ_Intern","DutchDisclaimer":"<p>Deze publicatie is enkel beschikbaar voor persoonlijk gebruik binnen de Innovocean site <br />en mag op geen enkele manier verder worden verspreid.</p>","FileFormat":".pdf","FileDescr":"pdf","InsPub":1,"InsID":36,"FileFormID":6,"LendableFlag":1,"PublicFlag":1,"orderLib":"A","Notes":null,"AccConID":null,"AccessConstraint":null,"LicURL":null}],"litstyles":[{"LitStyID":7,"Style":"Dissertation"}],"thespers":[{"PersID":19,"Surname":"Vincx","Firstname":"Magda","Initials":"M.","Role":"Promotor"},{"PersID":9285,"Surname":"Depestele","Firstname":"Jochen","Initials":"J.","Role":"Co-promotor"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":[{"ThesaurusTerm":"ANE, North Sea","ThestID":182108,"Acronym":"ASFA_GEOT","ThesTermPath":"ANE, North Sea"},{"ThesaurusTerm":"Beam trawls (bottom)","ThestID":842,"Acronym":"ASFA","ThesTermPath":"Beam trawls (bottom)"},{"ThesaurusTerm":"Trawling","ThestID":8742,"Acronym":"ASFA","ThesTermPath":"Catching methods > Net fishing > Trawling"}],"thestermsASFA":[{"ThesaurusTerm":"ANE, North Sea"},{"ThesaurusTerm":"Trawling"}],"taxtermsASFA":null,"geotermsASFA":[{"GeoTerm":"North Sea"}],"collections":null,"conf":null,"proj":null,"Physdatasets":null,"spcols":{"222":{"SpName":"BMB -
