C., Cherel, Y., Roberts, J., and Piatkowski, U. 2013. How do cephalopods become available to seabirds: can fish gut contents from tuna fishing vessels be a major food source of deep-dwelling cephalopods? \u2013 ICES Journal of Marine Science, 70:46\u201349. Cephalopods are important prey for numerous seabird species. However, the physical mechanisms by which cephalopods (particularly species considered as deep-dwelling) become available to seabirds are poorly understood, and it has recently been suggested that the discarded stomachs of gutted fish captured by tuna longliners can be a major source of deep-dwelling species. Here, we identify some deep-dwelling cephalopods that appear in the diet of seabirds, review the current knowledge of their vertical distribution, and compare the stomach contents of commercially captured tuna with those of seabirds foraging in the same area. The limited available information leads us to conclude that tuna longliners are unlikely to be a major source of deep-dwelling cephalopods for seabirds. However, much more information is required on the ecology of seabird prey, particularly commercially unexploited cephalopod species, which may be obtained from scientific cruises devoted to cephalopod biological research. In addition multispecies\/foodweb modelling studies may be required to explore potential interactions between seabirds, their predators and prey, and commercial fishing operations.<\/jats:p>","DOI":"10.1093\/icesjms\/fss167","type":"journal-article","created":{"date-parts":[[2012,10,25]],"date-time":"2012-10-25T00:56:45Z","timestamp":1351126605000},"page":"46-49","source":"Crossref","is-referenced-by-count":15,"title":["How do cephalopods become available to seabirds: can fish gut contents from tuna fishing vessels be a major food source of deep-dwelling cephalopods?"],"prefix":"10.1093","volume":"70","author":[{"given":"Jos\u00e9 C.","family":"Xavier","sequence":"first","affiliation":[{"name":"Institute of Marine Research, Department of Life Sciences, University of Coimbra, 3001-401 Coimbra, Portugal"},{"name":"British Antarctic Survey, Natural Environment Research Council, High Cross, Madingley Road, Cambridge CB3 0ET, UK"}]},{"given":"Yves","family":"Cherel","sequence":"additional","affiliation":[{"name":"Centre d'Etudes Biologiques de Chiz\u00e9, UPR 1934 du CNRS, BP 14, 79360 Villiers-en-Bois, France"}]},{"given":"Jim","family":"Roberts","sequence":"additional","affiliation":[{"name":"National Institute of Water and Atmospheric Research Ltd, Private Bag 14-901, Kilbirnie, Wellington, New Zealand"}]},{"given":"Uwe","family":"Piatkowski","sequence":"additional","affiliation":[{"name":"GEOMAR, Helmholtz-Zentrum f\u00fcr Ozeanforschung Kiel, D\u00fcsternbrooker Weg 20, D-24105 Kiel, Germany"}]}],"member":"286","published-online":{"date-parts":[[2012,10,24]]},"reference":[{"key":"2019081301260327900_FSS167C1","doi-asserted-by":"crossref","first-page":"143","DOI":"10.3354\/meps266143","article-title":"Cephalopod fauna of subantarctic islands: new information from predators","volume":"266","author":"Cherel","year":"2004","journal-title":"Marine Ecology Progress Series"},{"key":"2019081301260327900_FSS167C2","first-page":"113","article-title":"A review of the food of albatrosses","volume-title":"Albatross Biology and Conservation","author":"Cherel","year":"1998"},{"key":"2019081301260327900_FSS167C3","doi-asserted-by":"crossref","first-page":"281","DOI":"10.3354\/meps07587","article-title":"Resource partitioning within a tropical seabird community: new information from stable isotopes","volume":"366","author":"Cherel","year":"2008","journal-title":"Marine Ecology Progress Series"},{"key":"2019081301260327900_FSS167C4","doi-asserted-by":"crossref","first-page":"93","DOI":"10.3354\/meps188093","article-title":"Spawning cycle of onychoteuthid squids in the southern Indian Ocean: new information from seabird predators","volume":"188","author":"Cherel","year":"1999","journal-title":"Marine Ecology Progress Series"},{"key":"2019081301260327900_FSS167C5","doi-asserted-by":"crossref","first-page":"183","DOI":"10.3354\/meps207183","article-title":"Food and feeding ecology of the neritic-slope forager black-browed albatross and its relationships with commercial fisheries in Kerguelen waters","volume":"207","author":"Cherel","year":"2000","journal-title":"Marine Ecology Progress Series"},{"key":"2019081301260327900_FSS167C6","doi-asserted-by":"crossref","first-page":"1117","DOI":"10.1007\/s00227-002-0907-5","article-title":"Dietary evidence for spatial foraging segregation in sympatric albatrosses [Diomedea spp.] rearing chicks at Iles Nuageuses, Kerguelen","volume":"141","author":"Cherel","year":"2002","journal-title":"Marine Biology"},{"key":"2019081301260327900_FSS167C7","first-page":"1","article-title":"Cephalopoda in the diet of sperm whales of the southern hemisphere and their bearing on sperm whale biology","author":"Clarke","year":"1980","journal-title":"Discovery Reports"},{"key":"2019081301260327900_FSS167C8","doi-asserted-by":"crossref","first-page":"1053","DOI":"10.1098\/rstb.1996.0093","article-title":"Cephalopods as prey.
