Resumo: | Feeding habits of the cutlassfish, Trichiurus lepturus, in northern Rio de Janeiro. The aim of the present study was to describe the diet of the adult cutlassfish, Trichiurus lepturus, in northern Rio de Janeiro, through stomach content analysis. The sampling included 350 specimens measuring between 100 and 163cm in total length, collected from 2004 to 2006. For each prey species, the frequency of occurrence, density and biomass, body length and weight, and Index of Relative Importance (IRI) were calculated. The canniba- listic feeding behavior of the cutlassfish was also recorded. According to the IRI, the preferential prey species were the fishes T. lepturus, Pellona harroweri, Chirocentrodon bleekerianus, Lycengraulis grossidens, Peprilus paru, Chloroscombrus chrysurus, Odontognathus mucronatus, Stellifer brasiliensis and Isophisthus parvipinnis, and the crustacean Pleoticus muelleri. The cephalopods Loligo sanpaulensis and L. plei occurred occasionally in the stomach contents analyzed. The diet of T. lepturus in northern Rio de Janeiro was composed of pelagic and demersal prey species, associated with estuarine and coastal areas. The fish species and one crustacean species were the most representative items in its diet. |

A amostragem incluiu 350 espécimes, com comprimento total entre 100 e 163cm, coletados entre 2004 e 2006. Para cada espécie de presa calcularam-se as freqüências de ocorrência, numérica e de biomassa, porte (comprimento e peso) e Índice de Importância Relativa (IIR) na dieta. O comportamento alimentar de canibalismo foi registrado. De acordo com o IIR, os itens preferenciais foram os peixes T. lepturus, Pellona harroweri, Chirocentrodon bleekerianus, Lycen-graulis grossidens, Peprilus paru, Chloroscombrus chrysurus, Odontognathus mucronatus, Stellifer brasiliensis e Isophisthus parvipinnis, além do crustáceo Pleoticus muelleri. Os cefalópodes Loligo plei e L. sanpaulensis ocorreram ocasionalmente nos conteúdos estomacais analisados. Na costa norte do Rio de Janeiro, T. lepturus apresenta dieta composta por organismos neríticos de hábitos pelágicos e/ou demersais associados a áreas costeiras e estuarinas, sendo peixes e crustáceos os itens mais representativos na dieta.Universidade Federal de Santa Catarina2008-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n2p8310.5007/2175-7925.2008v21n2p83Biotemas; v. 21 n. 2 (2008); 83-902175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2008v21n2p83/18910Copyright (c) 2008 Vanessa Trindade Bittar, Bernardo de Figueiredo Leão Castello, Ana Paula Madeira Di Benedittoinfo:eu-repo/semantics/openAccessBittar, Vanessa TrindadeCastello, Bernardo de Figueiredo LeãoBeneditto, Ana Paula Madeira Di2018-03-07T18:11:57Zoai:periodicos.ufsc.br:article/20883Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T18:11:57Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
