Stratified sampling by onboard observers took place from February 1999 to March 2001 and data were collectcd from 165 tows during 52 fishing trips. Commercial target species included crustaceans: blue and red shrimp (<i>Aristeus antennatus</i>), deep-water rose shrimp (<i>Parapenaeus longirostris</i>), Norway lobster (<i>Nephrops norvegicus</i>); and fishes: seabreams (<i>Diplodus</i> spp. and <i>Pagellus</i> spp.), horse mackerels (<i>Trachurus</i> spp.) and European hake (<i>Merluccius merlaccius</i>). The trawl fisheries are characterised by considerable amounts of bycatch: 59.5% and 80.4% of the overall total catch for crustacean and fish trawlers respectively. A total of 255 species were identified, which belonged to 15 classes of organisms (137 vertebrates, 112 invertebrates and 6 algae). Crustacean trawlers had higher bycatch biodiversity. Bony fish (45.6% and 37.8%) followed by crustaceans (14.6% and 11.5%) were the dominant bycatch components of both crustacean and fish trawlers respectively. The influence of a number of factors (e.g. depth, fishing gear, tow duration and season) on bycatch and discards is discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Bycatch of crustacean and fish bottom trawl fisheries from southern Portugal (Algarve)","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":"bycatch; trawl fisheries; fish; crustacean; Algarve; Portugal","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2009-02-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000262997400016","VABBcode":null,"OpenAcc":0,"DOI":"10.3989/scimar.2008.72n4801"},"refs":null,"anarec":{"AnaID":130440,"PubliDate":2008,"Pagination":"801-814","XtraPublOfAnaID":null,"ISBN":null,"Volume":"72","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43791,"SerRR":"Scientia Marina (Barcelona).
