Data were obtained from 50 tows made by commercial trawlers fishing in the southwestern Gulf of Maine, Mean discard percentages (100 × fish discarded/fish caught) per tow, on a weight basis, were 93% for silver hake, 81% for American plaice, 76% for witch flounder, 56% for Atlantic cod, 41 % for goosefish, 20% for yellowtail flounder, and 11% for winter flounder. Mean discard percentages per tow on a numerical basis were slightly higher. Neither catch condition nor tow duration affected discard percentage, but discard percentage decreased with increasing depth for American plaice.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Discarding of commercial groundfish species in the Gulf of Maine shrimp fishery","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:35.408324","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2013-09-05","DateCreate":"2013-09-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1577/1548-8675(1992)012<0568:DOCGSI>2.3.CO;2"},"refs":null,"anarec":{"AnaID":228521,"PubliDate":1992,"Pagination":"568-580","XtraPublOfAnaID":null,"ISBN":null,"Volume":"12","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43447,"SerRR":"North American Journal of Fisheries Management.
