“…Samples were always taken during daytime, since personal underwater observations and information from the literature (Fogaça et al, 2003;Sabino & Castro, 1990;Barreto & Aranha, 2005) indicated that D. langei were active during daytime. Still, in the field, specimens were immersed in 10% formalin with the objective of stopping the digestive process, and after 48 h they were transferred to 70% alcohol for better conservation and to facilitate handling during dissection.…”

“…Deuterodon langei is considered a resident of deep or shallow areas, lotic or lentic waters, and various types of substrates (Aranha et al,1998;Fogaça et al,2003;Barreto & Aranha, 2005). Studies on D. langei diet had recently been carried out in littoral streams of Paraná State.…”

“…Characins display a wide range of feeding modes with herbivores, insectivores, carnivores and omnivores, showing great plasticity associated with seasonal, spatial and ontogenetic variations (Sabino & Castro, 1990;Kramer & Bryant, 1995b;Aranha et al,1998;Winemiller & Jepsen, 1998;Vitule & Aranha, 2002;Vilella et al,2002;Fogaça et al,2003;Barreto & Aranha, 2006) Deuterodon Eigenmann, 1907 (Characiformes, Characidae) is a very important genus with a large distribution in the Atlantic Forest, and is always frequent and abundant within fish assemblages of littoral rivers, mainly in South and Southeastern Brazil. Despite that, there are few studies of its ecology: Sabino & Castro (1990), Aranha et al (1998), Mazzoni & Petito (1999), Esteves & Lobón-Cerviá (2001), Vitule & Aranha (2002), Fogaça et al (2003), Barreto & Aranha (2005), Barreto & Aranha (2006), Vitule et al (2008). Deuterodon langei Travassos, 1957 is popularly called "lambari" and is one of seven currently recognized species of the genus, being endemic and very abundant in coastal streams of Paraná and north of Santa Catarina, southern Brazilian states (Aranha et al,1998;Lucena & Lucena, 2002;Vitule & Aranha, 2002;Barreto & Aranha, 2005;Vitule et al, 2008).…”

Information related to the diet of one species always contributes to the knowledge of its bionomy and the functioning of the ecosystem in which the species lives. Therefore, understanding the feeding ecology of one fish population and its ontogenetic, spatial and temporal aspects help to understand the structure of fish assemblages and river communities. Knowledge of this structure is essential for habitat management and biodiversity conservation. The feeding ecology of Deuterodon langei Travassos, 1957 was studied through analyses of diet composition, sharing of resources, feeding strategy and contribution of food items to the width of its niche. The analysis included an assessment of ontogenetic, spatial and seasonal variations. The species was considered omnivorous with great plasticity caused by seasonal variation in food availability throughout the river basin, but mainly through ontogeny. The diet of smaller individuals revealed a predominance of insects and other arthropods, while the diet of larger specimens showed allochthonous plant items as the main components. The low intestinal quotient (IQ) values for the smaller individuals were accounted for their mainly insectivorous diet. The greater relative length of the intestine can account for the greater plasticity of the adult diet, enabling them to use diet items of larger size and more difficult digestion, such as plant items. Therefore, shifts in feeding ecology during growth are confirmed in this omnivorous tropical river fish, strengthening the concept that, when comparing food habits among species, fish size must be taken into account. This study also provides needed information regarding the feeding ecology of fishes intrinsically associated with the Atlantic rainforest, one of the most threatened and biodiverse ecosystems of the planet.Informações relacionadas à alimentação de uma espécie contribuem para o conhecimento de sua bionomia e funcionamento do ecossistema no qual ela vive. Desta forma, entender a ecologia alimentar de uma população de peixes e seus aspectos ontogenéticos, temporais e espaciais auxiliam na compreensão da assembléia de peixes e de toda a comunidade de um rio. Reconhecer tal estrutura é fundamental para o manejo e conservação da biodiversidade do habitat. A ecologia alimentar de Deuterodon langei Travassos, 1957 foi analisada por meio da composição da dieta, partilha de recursos, estratégia alimentar e contribuição dos itens alimentares para o nicho alimentar. As análises incluem uma abordagem das variações ontogenéticas, espaciais e temporais. A espécie foi considerada onívora com uma grande plasticidade alimentar causada pela variabilidade sazonal na disponibilidade de recursos e ao longo da bacia hidrográfica, mas principalmente ao longo de sua ontogenia. A dieta dos indivíduos menores revelou uma predominância de insetos e outros artrópodes, enquanto nos indivíduos maiores ocorreu um predomínio de vegetais alóctones. Os baixos valores de Quociente Intestinal (IQ) para os indivíduos menores foram associados a uma dieta ...

“…Rhamdia quelen (Quoy and Gaimard, 1824) is distributed from southern Mexico to the River Plate, one of the most euritópicos neotropical fish, living in small streams, lakes and larger rivers, dwelling during day light under or beneath wood logs and rocks (Menezes et al, 2007). It seems to be more conspicuous in still waters (Barreto and Aranha, 2005). Its behavior suggests a benthonic way of life and a broad feeding spectrum, by feeding on terrestrial and aquatic insects, crustaceans, plants and fish (Casatti et al, 2001;Casatti and Castro, 2006).…”

The aim of this study was to compare the food composition of Rhamdia quelen in four distinct order rivers. It was performed at a low part at the basin of the Sorocaba river in systems classified as first (Anastácio stream), second (Nego stream), fifth (Tatuí river) and sixth (Sorocaba river) orders. Collections were performed every month between January and December of 2011. The stomach contents were examined by using the alimentary index (IAi) and compared by the non-parametric method non-metric multidimensional scale ranking (NMDS) with the Spearman rank correlation. A diet difference was observed for individuals of the smaller systems (Anastácio and Nego streams) and the larger ones (Tatui and Sorocaba rivers), represented respectively by allochthonous and autochthonous organisms compounding their diets. Marginal vegetation and its interaction with the water conditions may respond to these composition differences.Keywords: Sorocaba river basin, alochthonous items, autochthonous items, opportunist fish, Atlantic. Rain Forest. Diferenças na alimentação de Rhamdia quelen em quatro diferentes ordens de sistemas lóticos ResumoEste estudo teve como objetivo comparar a alimentação de Rhamdia quelen em quatro diferentes ordens de sistemas lóticos. O estudo foi realizado em um trecho da parte baixa da bacia do rio Sorocaba, em sistemas de primeira (Anastácio stream), segunda (Nego stream), quinta (Tatuí river) e sexta (Sorocaba river) ordens. As coletas foram realizadas mensalmente entre janeiro a dezembro de 2011. Os conteúdos estomacais foram analisados pelo índice alimentar (IAi) e comparados pelo método de escalonamento multidimencional não-metrico (NMDS), juntamente com a correlação de Spearman. Foi percebida uma diferença na dieta dos indivíduos dos sistemas menores, córregos Anastácio e Nego e os rios maiores, rios Tatuí e Sorocaba. Nos córregos Nego e Anastácio houve maior incidência de itens de origem alóctone na dieta, enquanto que nos rios Tatuí e Sorocaba foi observado o inverso. A diferença nos itens consumidos pode depender da ordem dos sistemas lóticos e da interação entre a vegetação marginal com o sistema aquático.

A fish-based Index of Biotic Integrity (IBI) was adapted for use in a stream of the heavily impacted Piracicaba River basin in southeastern Brazil. The influences of land use (mainly sugar-cane crops) and an urban area on the fish community were investigated at ten sites along a 17 km-long stream during the dry and rainy season. The IBI varied with the season and location along the stream, reflecting differences between the agricultural and urban sites, which were more pronounced during the dry season. The final index was positively correlated with a Habitat Quality Index (dry season) but not with a Water Quality Index. The results can be viewed as a tool for assessing and monitoring the ecological health of streams in this watershed.
