Stable isotopes ( 13C and 15N) were used toexamine the origin of organic matter for the most representativedemersal species of the SW Icelandic Wshery,accounting for over 70% of landings of those species in theNorth Atlantic. Samples were collected during a 2-weekperiod in early September 2004 from landings and directlyduring Wshing cruises. Stable isotopes showed that particulateorganic matter and sedimentary organic matter were atthe base of the food web and appeared to Wll two diVerentcompartments: the pelagic and the benthic. The pelagicrealm was composed of only capelin and sandeel; krill andredWsh occupied an intermediate position between pelagicand benthic realms; while anglerWsh, haddock, cod and lingresulted as the true demersal species while tusk, rays andplaice were strongly linked to the benthic habitat.
