“…Despite the fact that Monteiro et al (2009) andPimentel &Joyeux (2010) suggested temporal changes in the diet composition of snappers in the Brazilian coast, we did not observe seasonal variation for L. analis. We believe that this variation is related with the local changes in prey availability (Randal, 1967).…”

“…Even though few stomachs of larger individuals were analyzed, similar feeding pattern was also observed for L. analis in the West Indies (Randall, 1967), in the Caribbean coast of Panama (Heck & Weinstein, 1989) in the Cuban platform (Claro, 1981;Sierra et al, 2001) and Southeastern Brazil (Pimentel & Joyeux, 2010). This adaptation probably aims to reduce the competition for food or meet physiological needs that the fish may have during its ontogenetic development in terms of migration, sexual maturation and/or reproduction (Braga & Braga, 1987;Gerking, 1994;Sierra et al, 2001).…”

“…Several studies have already reported the importance of these food items for L. analis (Randall, 1967;Claro, 1981;Guevara et al, 1994;Sierra & Popova, 1997;Duarte & Garcia, 1999;Sierra et al, 2001;Claro & Lindeman, 2004;Pimentel & Joyeux, 2010), and also for other congeners as L. synagris (Linnaeus, 1758) (Duarte & Garcia, 1999;Pimentel & Joyeux, 2010), L. campechanus (Poey, 1860) (Lee & Szedlmayer, 2004), L. guttatus (Steindachner, 1869) RojasHerrera et al, 2004), L. peru (Nichols & Murphy, 1922) (Santamaría-Miranda et al, 2003, L. argentiventris (Peters, 1869), and L. colorado Jordan & Gilbert, 1882 (Molina et al, 2005).…”

“…We believe that this variation is related with the local changes in prey availability (Randal, 1967). In fact, Monteiro et al (2009) andPimentel &Joyeux (2010) worked in mangrove environments, which are often subjected to more acute environmental changes than are reef faunas (Sierra et al, 2001).…”

“…Available evidences indicate that the diet of L. analis include fishes, shrimps, crabs, gastropods, and cephalopods (Allen, 1985;Heck & Weinstein, 1989;Claro & Lindeman, 2004;Pimentel & Joyeux, 2010), a general pattern for the family Lutjanidae (Duarte & Garcia, 1999;Santamaría-Miranda et al, 2003;Lee & Szedlmayer, 2004;Rojas-Herrera et al, 2004;Molina et al, 2005). Although snappers are generally considered nocturnal predators (Claro & Lindeman, 2004), L. analis fed diurnally (Watanabe, 2001), showing a high variability in foraging styles, according to fish size and time of day (Mueller et al, 1994).…”

Feeding ecology of Lutjanus analis (Teleostei: Lutjanidae) from Abrolhos Bank, Eastern Brazil

Diet and feeding ecology of the mutton snapper Lutjanus analis were investigated in the Abrolhos Bank, Eastern Brazil, the largest and richest coral reefs in the South Atlantic, where about 270 species of reef and shore fishes occur. To evaluate seasonal and ontogenetic shifts in the diet, specimens of L. analis were obtained through a fish monitoring program in four cities in southern Bahia State, from June 2005 to March 2007. Stomachs from 85 mutton snappers that ranged in size from 18.1 to 74.0 cm TL were examined. Prey were identified to the lowest possible taxon and assessed by the frequency of occurrence and volumetric methods. Variations in volume prey consumption were evaluated using non-metric multi-dimensional scaling ordination, analysis of similarity, and similarity percentage methods. Significant differences in diet composition among size classes were registered, whereas non significant differences between seasons were observed. Considering size-classes, food items consumption showed important variations: juveniles (<34.0 cm TL) fed mostly on crustaceans, sub-adults (34.1-50.0 cm TL) showed a diversified diet and adults (>50.1 cm TL) consumed basically fish, mostly Anguiliformes. Lutjanus analis is an important generalist reef predator, with a broad array of food resources and ontogenetic changes in the diet. This snapper species plays an important role on the trophic ecology of the Abrolhos Bank coral reefs.Foram avaliadas a dieta e a ecologia alimentar da cioba Lutjanus analis no Banco dos Abrolhos, Leste do Brasil. O Banco dos Abrolhos abrange os maiores e mais diversos recifes de corais do Atlântico Sul, onde cerca de 270 espécies de peixes recifais e costeiros ocorrem. Para a avaliação das variações sazonais e ontogênicas na dieta, exemplares de L. analis foram obtidos através de um programa de monitoramento em quatro cidades do extremo sul da Bahia, entre junho de 2005 e março de 2007. Estômagos de 85 exemplares com comprimento total variando entre 18,1 e 74,0 cm foram examinados. Os itens alimentares foram identificados até o menor nível taxonômico possível e avaliados através dos métodos de frequência de ocorrência e volumétrico. Variações no consumo das presas foram avaliadas através do método de escalonamento multidimensional não-métrico e métodos de análise de similaridade e percentagem de similaridade. Diferenças significativas na dieta foram observadas entre as classes de tamanho, porém estas não foram detectadas entre as estações do ano. Considerando as classes de tamanho, os itens consumidos apresentaram importantes variações: os juvenis (<34,0 cm CT) alimentaram-se preferencialmente de crustáceos, os subadultos (34,1-50,0 cm CT) apresentaram uma dieta diversificada e os adultos (>50,1 cm CT) consumiram basicamente peixes, principalmente Anguiliformes. Lutjanus analis é um importante predador recifal generalista, que consome um amplo espectro de presas, apresentando mudanças ontogênicas na dieta. Esse lutjanídeo desempenha um importante papel na ecologia trófica dos recifes de corais ...

The genus Haemulon contains some of the most abundant and ecologically important reef fishes in the South Atlantic Ocean. However, their life history attributes have not been widely studied. Knowledge of ontogenetic changes in their resource use is critical to understanding the processes structuring natural communities. The present study analysed ontogenetic diet changes and food partitioning in Haemulon spp. We collected stomach contents from 276 individuals of four different size classes from four sympatric species (H. aurolineatum, H. parra, H. plumieri and H. squamipinna). There was a significant difference in the proportions of prey types between both species and size classes, providing evidence of food partitioning. Moreover, the Bray-Curtis similarity index revealed two distinct groups. The first consisted of larger-sized fish that consumed larger food items and the second group consisted of smaller individuals that fed on small invertebrates. There was an abrupt shift in the diet of Haemulon spp. at around 10.0 cm total length, a size that corresponds with the greatest morphological changes in the genus. Additionally, the diet overlap calculated by Pianka's index was more evident in smaller and larger size classes than in intermediate individuals. Together, these observations suggest Haemulon species undergo ontogenetic diet changes and food partitioning within species and size classes that are associated with changes in their habitat use, alongside morphological changes. Further research is needed to determine their ecomorphology and the competitive mechanisms that allow the coexistence of several sympatric and ecologically similar species of the genus Haemulon.
