“…The presence of fishes and principally crustaceans in the stomach contents of Sciaenidae fishes is relatively common, as found in several studies, for instance of Bairdiella ronchus in south coast of Brazil (Vendel & Chaves 1998), Stellifer rastrifer in south coast of Brazil (Chaves & Vendel 2008), Micropogonias furnieri in Venezuela (Ruiz et al 2001), Isopisthus parvipinnis, Larimus breviceps in south-western Atlantic (Soares & Vazzoler 2001) and Menticirrhus americanus in southeastern Brazil (Turra et al 2012). …”

Resumen.-Se estudiaron los hábitos alimenticios de la pescadilla real Macrodon ancylodon basado en 280 muestras en la costa de la provincia de Mar anhão, noreste de Brasil . La dieta mostró un predominio de peces, cru stáceos y ocasionalmente cefalópodos. Las dietas de los machos y hembras fueron similares y se encontraron diferencias en la proporción de presas entre los juveniles, subadultos y adultos. Durante la temporada de lluvias las presas fueron más diversas que en la temporada seca. En la estación seca M. ancylodon se alimenta más de Penaeidae (Penaeus sp. y Penaeus schmitti), Callinectes sp. y Engraulidae (Cetengraulis sp.). Se observó un aumento del espectro de alimentos en la temporada de lluvias, con presas de 5 especies de peces (Anchovia clupeoides, Cetengraulis edentulus, Macrodon ancylodon, Mugil curema y Sardinella brasiliensis), 3 especies de crustáceos (Penaeus schmitti, Parapenaeus politus y Callinectes sp.) y 2 cefalópodos (Loligo sp. y Loligo plei). Las diferencias en la ingestión de presas se encontraron durante el año, en la estación de lluvia, donde los individuos de esta especie presentaron mayores contenidos estomacales. El canibalismo se encontró con mayor intensidad para los peces maduros. Palabras clave: Pescadilla real, dieta, contenido del estómago, MaranhãoAbstract.-The feeding habits of Macrodon ancylodon were studied based on 280 specimens from the Maranhão coast, northeast Brazil. The diet showed a predominance of fishes, crustaceans and occasionally cephalopods. The diets of males and females were similar and difference was found in the proportion of prey items among juveniles, sub adults, and adults (P > 0.05). During rainy season the prey items were more diverse than dry season. In the dry season M. ancylodon feeds more Penaeidae (Penaeus sp. and Penaeus schmitti), Callinectes sp. and Engraulidae (Cetengraulis sp.). An increase of food spectrum was observed in rainy season, preyed upon 5 species of fish ( Anchovia clupeoides, Cetengraulis edentulus, Macrodon ancylodon, Mugil curema and Sardinella brasiliensis), 3 species of Crustacea (Penaeus sp., Penaeus schmitti, Parapenaeus politus, and Callinectes sp.) and 2 Cephalopoda (Loligo sp. and Loligo plei). Differences in the ingestion of prey items were found during the year, where in the rainy season this species presented larger stomach contents. Cannibalism was encountered more intensively for mature fish.

“…It is common for invertivorous fishes to show higher feeding activity than piscivorous ones (Lucena et al, 2000;Soares and Vazzoler, 2001;Vitule and Aranha, 2002;Braga, 2005;Fagundes et al, 2007). The variations in feeding activity among the seasons of the year are closely related to the lowest fullness degree obtained in the winter, with this season differing significantly from the others.…”

“…Regarding the Sciaenidae diet, marine species consume mainly decapod crustaceans (Lunardon, 1990;Vazzoler, 1991;Figueiredo and Vieira, 1998;Vendel and Chaves, 1998;Soares and Vazzoler, 2001;Branco et al, 2005). Freshwater sciaenids consume mainly fish and insects (Mourão and Torres, 1984;Hahn et al, 1997Hahn et al, , 1999Alvim and Peret, 2004;Bennemann et al, 2006;Fugi et al, 2007;Pacheco et al, 2008).…”

“…Among these genera, six are restricted to freshwater and four, Pachyurus, Pachypops, Plagioscion and Petilipinnis, are endemic to South America (Casatti, 2003). The food items most often consumed by members of this family are benthic animals such as crustaceans, polychaetes, mollusks, insects and small fish, and sometimes algae (Mourão and Torres, 1984;Lunardon, 1990;Vazzoler, 1991;Hahn et al, 1997;Figueiredo and Vieira, 1998;Vendel and Chaves, 1998;Hahn et al, 1999;Soares and Vazzoler, 2001;Alvim and Peret, 2004;Branco et al, 2005;Bennemann et al, 2006;Fugi et al, 2007;Pacheco et al, 2008). The sciaenid Pachyurus bonariensis occurs naturally in the rivers of the Paraná-Paraguay-Uruguay system, downstream from the Itaipu Reservoir, including Argentina, Brazil, Paraguay and Uruguay (Casatti, 2001) The P. bonariensis diet was studied once, in two lakes (locally called bays) of the Pantanal, where it had a diet composed mainly of Chironomidae and Ephemeroptera, with important ontogenetic shifts (Fugi et al, 2007).…”

Knowledge of the feeding ecology of fish is essential for understanding the functioning of freshwater communities. Here we report on an analysis of the diet of Pachyurus bonariensis Steindachner, 1879, a freshwater sciaenid. Fish were collected bimonthly from December 1999 to January 2002 at three locations along the Ibicuí River in the Rio Grande do Sul State, Brazil. At each location, the specimens were collected in both lentic and lotic environments. The stomachs of 324 fish were analysed for contents and fullness. The main items were Ephemeroptera, Diptera (larvae), Trichoptera and Odonata. Annelida, plant matter, Decapoda, Diptera (pupae), Coleoptera and Mollusca were present in small amounts. The fish consumed smaller amounts of food in winter than in other seasons. The most important source of dietary variation for P. bonariensis was the ontogenetic, related to intrinsic biological characters. However, spatial variation was also found, suggesting that this species can adapt its diet to environmental changes. Although P. bonariensis showed ontogenetic and spatial variations in the main items consumed, the main items were always insects, characterising P. bonariensis as a fish with an insectivorous feeding habit in the Ibicuí River.Keywords: feeding activity, diet composition, trophic ecology, insects, fishes. Biol., 2010, vol. 70, no. 3, p. 503-509 the dominant species (Behr, 2005). For this, the dietary composition and the feeding activity were studied, and its ontogenetic, seasonal and spatial variations. The dietary composition was analysed to investigate, in Ibicuí River, its insectivorous specialised diet (Fugi et al., 2007). The ontogenetic, seasonal and spatial variations in trophic spectrum were also investigated to confirm its specialised diet at different situations and to analyse what is the mainly source of dietary variations, those principally due to food availability, seasonal and spatial, or the ontogenetic variation. Its feeding activity was analysed to investigate the influence of year seasons and spatial heterogeneity on food ingestion. Ecologia trófica de Pachyurus bonariensis

“…Ubatuba is a city in the northern coast of São Paulo State, a place where marine fishes have been studied for decades and although several works regarding marine fish ecology were conducted off the coast of Ubatuba (e.g., Nonato et al, 1983;Braga & Goitein, 1984;Rossi-Wongtschowski & Paes, 1993;Cunningham, 1995;Giannini & Paiva Filho, 1995;Rocha & Rossi-Wongtschowski, 1998;Soares & Vazzoler, 2001;Vianna et al, 2004;Souza et al, 2008;Rocha et al, 2010;Gondolo et al, 2011), none of them dealt with long-term variation of ecological parameters in the southeastern region of Brazil. In addition, as stated by Rossi-Wongtschowski et al (2009) and Menezes (2011), although the marine fishes off the coast of São Paulo are relatively well known in relation to the rest of the Brazilian coast, much is yet to be done concerning our knowledge of these organisms.…”
