Última Mercury and stable isotopes (δ15N and δ13C) as tracers during the ontogeny of Trichiurus lepturus 83 Beneditto,Ana Paula Madeira Di; Bittar,Vanessa Trindade; Rezende,Carlos Eduardo de; Camargo,Plínio Barbosa; Kehrig,Helena Amaral. This study applies total mercury (THg) concentration and stable isotope signature (δ15N and δ13C) to evaluate the trophic status and feeding ground of Trichiurus lepturus during its ontogeny in northern Rio de Janeiro, south-eastern Brazil. The trophic position of T. lepturus is detected well by THg and δ15N as the sub-adult planktivorous specimens are distinct from the adult carnivorous specimens. The δ13C signatures suggest a feeding ground associated with marine coastal waters that are shared by fish in different ontogenetic phases. The diet tracers indicated that the fish feeding habits do not vary along seasons of the year, probably reflecting the prey availability in the study area. This fish has economic importance and the concentration of THg was... Tipo: Info:eu-repo/semantics/article Palavras-chave: Carbon; Diet tracers; Nitrogen; Trace element; Trichiurus lepturus. Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252013000100211 Feeding preference of adult females of ribbonfish Trichiurus lepturus through prey proximate-composition and caloric values 83 Bittar,Vanessa Trindade; Awabdi,Danielle Rodrigues; Tonini,William Cristiane Teles; Vidal Junior,Manuel Vazquez; Di Beneditto,Ana Paula Madeira. In the present study we analysed the proximate-composition and caloric values of the preferred prey consumed by ribbonfish, Trichiurus lepturus L. 1758 (adult females), that are distributed in the inner continental shelf from northern Rio de Janeiro State, southeastern Brazil (~22ºS), assessing the potential of nutritional and energetic approach as a tool to understand the feeding selective pattern of this marine top carnivore. The preferred prey of this predator composed of fish co-specifics, Pellona harroweri, Chirocentrodon bleekerianus, Lycengraulis grossidens, Peprilus paru, squid Doryteuthis plei, and shrimp Xiphopenaeus kroyeri were collected from 2007 to 2010 for proximate-composition (water, protein, lipid, ash, and carbohydrate) and caloric value...
