“…The stomach content was sorted taxonomically and the state of digestion (1-fresh prey; 2 -partially digested prey; 3 -digested prey) according to Soares & Apelbaum (1994), was assigned for individual items. The occurrence and mass of the food items, grouped into taxa, were recorded.…”

Food habits and daily feeding activity of fish populations are important ecological variables for understanding their role in the ecosystem. Diel changes in feeding activity and dietary composition of juvenile whitemouth croaker Micropogonias furnieri, shortfin corvina Isopisthus parvipinnis, shorthead drum Larimus breviceps and of juvenile and adult banded croaker Paralonchurus brasiliensis were investigated from samples taken over a 24 hours period from 4 to 5 September 1987 on the continental shelf off South-eastern Brazil. Whitemouth croaker and banded croaker had a benthic diet based on polychaetes and some caridean shrimps and showed no diel feeding pattern. Shortfin corvina and shorthead drum fed on crustaceans and teleostean fish, the former species primarily on pelagic sergestid shrimps and benthic caridean shrimps, and the latter mainly on pelagic sergestid shrimps, mysidacean and benthic caridean shrimps. Shortfin corvina is primarily a diurnal feeder, but preyed on some items only at night. Shorthead drum is a night feeder, with minimum stomach fullness values between dawn and daytime, and maximum values between dusk and night time.Key words: diel feeding, food habits, Teleostei, Sciaenidae, South-western Atlantic. RESUMO Variações nictemerais na alimentação e na atividade alimentar de peixes Sciaenidae do Atlântico sudoeste, BrasilInformações sobre o hábito alimentar e a atividade alimentar diária de populações de peixes são variá-veis de fundamental importância para entender seu papel em um ecossistema aquático. Investigações sobre esses aspectos foram realizadas em jovens da corvina (Micropogonias furnieri), da tortinha (Isopisthus parvipinnis) e da oveva (Larimus breviceps) e em jovens e adultos de maria luiza (Paralonchurus brasiliensis), cujas amostras foram obtidas em um ciclo de 24 horas (4 a 5 de setembro de 1987), na plataforma continental do sudeste do Brasil. A corvina e a maria luiza se alimentaram, principalmente, de poliquetas e camarões carídeos e não apresentaram um padrão claro de atividade alimentar. A tortinha e a oveva apresentaram dieta semelhante, composta de crustáceos e peixes teleósteos; ambas tiveram como presas principais os camarões pelágicos sergestídeos e os camarões bentônicos carídeos, e a oveva, além dessas duas presas, misidáceos. A tortinha apresentou, principalmente, hábito alimentar diurno, mas se alimentou de algumas presas em períodos de escuro. A oveva apresentou hábito alimentar noturno, com registros dos maiores valores de repleção estomacal entre o anoitecer e o período de escuro.Palavras-chave: atividade alimentar diária, hábito alimentar, Teleostei, Sciaenidae, Atlântico sudoeste.Rev.

“…Afterwards, the contents were identified in taxonomic groups and weighed. The digestion degree of each prey was registered in three levels, as follows: undigested, with no signs of digestion = 1; partially digested, but identifiable = 2; and digested without identification with presence of otoliths, crystalline, and other appendages = 3 (Soares and Apelbaum, 1994).…”

Analysis of food habits of skate Rioraja agassizii (Elasmobranchii, Rajidae) from southern Brazil

Catches and exports of skate Rioraja agassizii place this species as "vulnerable to extinction" on the IUCN Red List; therefore, biological and ecological knowledge becomes an important instrument for its conservation control. This study described and quantified the diet composition of R. agassizii by means of stomach analysis contents in the periods 2005-2006 and 2012-2013. We analyzed and quantified stomach contents in terms of abundance (%N), weight (%M), frequency of occurrence (% FO), and index of relative importance (IRI). The results showed differences in the food rates between the periods. However, the groups of food items were the same: Teleostei fish, decapods, and mollusks. In 2005-2006, the diet consisted mainly of shrimp, however, in 2012-2013 it consisted of fish, followed by decapods, especially shrimps. The differences in diets may be attributed to shrimp abundance, which do not characterize a change in the eating habits in 2012-2013, because, in addition to fish, shrimps were also important food sources. The presence of a certain prey is more related to its availability rather than the feeding preference of skate. The amount of ingested items is associated to biological and environmental factors, so that further studies relating diet with capture area, seasonality, depth, and other factors should be conducted.Keywords: diet, feeding ecology, feeding preference, prey, stomach content. Análise quantitativa dos hábitos alimentares da raia Rioraja agassizii (Elasmobranchii, Rajidae) do Sudeste e Sul do Brasil ResumoA raia-santa, Rioraja agassizii é uma espécie endêmica da qual pouco se conhece sobre sua biologia e ecologia, o que a leva a ser classificada como "vulnerável a extinção". O objetivo foi identificar e quantificar a composição da dieta alimentar da R. agassizii através da análise do conteúdo estomacal de exemplares capturados nos períodos de 2005-2006 e 2012-2013. Foram analisados os conteúdos alimentares e quantificados em abundância (N%), peso (M%), frequência de ocorrência (FO%) e índice de importância relativa (IRI) de cada item. Os resultados mostraram que em 2012-13 a dieta foi composta por peixes, seguido de decápodes, especialmente camarões, entretanto em 2005-06 foi composta basicamente por camarões. A diferença nas dietas não quer dizer que os hábitos alimentares mudaram, pois em 2012-13 além dos peixes, os camarões também foram classificados como maior importância alimentar. Considerando que a quantidade e variedade dos itens ingeridos está relacionada, principalmente, a fatores ambientais são necessários mais estudos que relacionem áreas de captura, sazonalidade e profundidade.Palavras-chave: dieta, ecologia alimentar, preferencia alimentar, presa, conteúdo estomacal.

ABSTRACT. The distribution, size structure, and feeding of three sea robin species belonging to the family Triglidae (Bellator brachychir, Prionotus nudigula and Prionotus punctatus) were studied based on specimens caught with bottom trawls on the continental shelf of Campos Basin, southeastern Brazil. The two Prionotus species were more concentrated in the inner shelf (<50 m), while B. brachychir was generally more abundant on the outer shelf (50-100 m). In general, the three species showed a carcinophagous diet, but with small overlap in their main preys. While amphipods was the most important prey to B. brachychir, isopods and shrimps were the basic food item found in P. nudigula and P. punctatus diet, respectively. This reduction in interspecific competition for food was followed by some degree of spatial segregation and thermal preferences for each species. Keywords: sea robin, Triglidae, distribution, feeding ecology, Campos Basin, southeastern Brazil.Distribución y hábitos alimentarios de tres especies de rubio (Bellator brachychir, Prionotus nudigula y Prionotus punctatus) en la cuenca de Campos, sureste de Brasil RESUMEN. La distribución, estructura de tamaños, y la alimentación de tres especies de rubio pertenecientes a la familia Triglidae (Bellator brachychir, Prionotus nudigula y Prionotus punctatus) se estudiaron sobre la base de ejemplares capturados con redes de arrastre de fondo en la plataforma continental de la cuenca de Campos, en el sureste de Brasil. Las dos especies de Prionotus estaban más concentradas en la plataforma interior (<50 m), mientras que B. brachychir fue generalmente más abundante en la plataforma exterior (50-100 m). En general, las tres especies mostraron una dieta carcinófaga, pero con pequeño solapamiento en sus principales presas. Los anfípodos fueron la presa más importante de B. brachychir, los isópodos y camarones fueron el alimento básico encontrado en la dieta de P. nudigula y P. punctatus, respectivamente. Esta reducción de la competencia interespecífica por alimentos fue seguida por un cierto grado de segregación espacial y preferencias térmicas para cada especie. Palabras clave: rubio, Triglidae, distribución, ecología alimentaria, cuenca de Campos, sureste de Brasil.
