Forty experimental fishing trials were carried out over a 1-year period with six combinations of small mesh (100, 120 and 140 mm) inner and large mesh (600 and 800 mm) outer panels. On average, 43.8 ± 12.2 (SD) (individuals 1000 m<sup>−1</sup> of net) of non-commercial invertebrates were discarded, accounting for 48% and 65% of the total catch and total discards by numbers, respectively. Within non-commercial invertebrates discards, the six most abundant species by number were <i>Phallusia mammillata</i> (Cuvier) (27.5%), <i>Cymbium olla</i> (L.) (13.0%), <i>Sphaerechinus granularis</i> (Lamarck) (11.3%), <i>Paracentrotus lividus</i> (Lamarck) (10.9%), <i>Astropartus mediterraneus</i> (Risso) (8.2%) and <i>Astropecten aranciacus</i> (L.) (8.1%); Echinoderms (43.1%) particularly important. The highest and lowest discard ratios were found in autumn and winter, respectively. Discards generally decreased with depth, varied considerably in relation to soak time and were not related to mesh size combinations. Trammel nets seem to be the most important gear in terms of ecological impacts on benthic invertebrates compared with other coastal fishing gears and at the depths studied (15–60 m).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Non-commercial invertebrate discards in an experimental trammel net fishery","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:31:40.879959","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"    biodiversity;by-catch;discards;fisheries;gear selectivity;invertebrates","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2017-01-11","DateCreate":"2017-01-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000255703900004","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/j.1365-2400.2008.00607.x"},"refs":null,"anarec":{"AnaID":282558,"PubliDate":2008,"Pagination":"199-210","XtraPublOfAnaID":null,"ISBN":null,"Volume":"15","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42700,"SerRR":"Fisheries Management and Ecology.
