“…The shift of food habits with size of fish, especially Sciaenidae fishes, is well known (Chao & Musick 1977, McMichael & Ross 1987, Vendel & Chaves 1998, Fonseca & Castro 2000, Raymundo-Huizar et al 2005, Giberto et al 2007, Palmeira & Monteiro-Neto 2010. Usually a big fish eat larger prey and variety of food organisms, while the smaller fish consume smaller prey and less diversity of food items.…”

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.

“…Food items were analyzed using the following methods: percentage frequency of occurrence (%O) (Hyslop, 1980) and relative abundance (%A) (Marshal & Elliott, 1997) using the points method (Vendel & Chaves, 1998), which accounts for gut fullness (Hyslop, 1980). The values of "%O" and "%A" were combined through the index of preponderance, which produces a single value for each attribute based on frequency of occurrence (%O) and relative abundance (%A), using the equation:…”

This paper presents the results of the first analysis of the natural diet of Hippocampus reidi, one of the most sought after seahorse species in the international aquarium trade. Its main goals were to investigate food items and prey categories consumed by the species, and to discuss feeding strategy and inter and intra-individual components of niche breadth. Data were gathered from October 2005 to September 2006 at the Mamanguape estuary, State of Paraíba, NE Brazil. Food items from seahorses anaesthetized with clove oil were obtained by using a modified version of the flushing method, and were counted and identified to the lowest possible taxonomic level. Specimens were marked and had their height, sex, life and reproductive stage recorded, and then returned to the same place where they were found for the further assessment of anaesthetization/gut flushing on seahorses. Food items were analyzed using frequency of occurrence, relative abundance, index of preponderance and prey-specific abundance using the points method. The graphic method of Amundsen et al. (1996) was used to interpret the feeding strategy and contribution to niche breadth. Nematodes and crustaceans were the most important items found, the latter item usually being the most commonly found in the gut contents of syngnathids. No significant differences in diet composition were found between reproductive stages, however, a higher proportion of large items were consumed by the larger seahorses. The feeding strategy and niche breadth analysis suggests that H. reidi has a generalist feeding strategy, with high variation between phenotypes. Our results suggest that the anaesthetization-flushing technique has the potential to be a useful tool in seahorse research.Este artigo apresenta os resultados do primeiro estudo sobre a alimentação natural de Hippocampus reidi, uma das espécies de cavalos-marinhos mais intensamente comercializadas pelo mercado aquarista. Seus principais objetivos foram descrever os itens alimentares e categorias de presas consumidos pela espécie e fornecer informações acerca da estratégia alimentar e dos componentes inter e intra-individuais para a largura de nicho. As amostragens foram realizadas mensalmente por meio de busca intensiva, entre outubro de 2005 e setembro de 2006, no estuário do rio Mamanguape, Paraíba, onde os cavalos marinhos foram marcados, anestesiados com óleo de cravo e submetidos à técnica da lavagem estomacal. Para cada cavalo-marinho registrouse a altura, sexo, estágio de vida e estado reprodutivo. Após a coleta de dados, todos os cavalos-marinhos foram devolvidos ao mesmo local onde haviam sido encontrados e o material obtido através da lavagem foi identificado, em laboratório, até o menor nível taxonômico possível, com o auxílio de especialistas. Os itens alimentares foram descritos através de freqüência de ocorrência, abundância relativa, índice de preponderância e abundância específica; já a estratégia alimentar e contribuição para a largura de nicho foram descritos através do método de Amundsen.

“…The juveniles of A. parva and H. clupeola, probably in their first year, corresponded to 69% of the annual production and, through their planktotrophic diet, these fish are the main direct connection with the high primary production in the region. Other species such as G. genidens, B. ronchus, C. arenaceus, C. spilopterus, S. greeleyi, and S. testudineus, also important numerically, are mainly carnivorous at the base of the food chain and are, therefore, favored by the increment of the secondary production in the area (Chaves & Vendel, 1996;Chaves & Serenato, 1998;Vendel & Chaves, 1998).…”

The fish assemblage in a mangrove tidal creek was studied in monthly collections between August 1998 and July 1999 in the quadrature low tide and high tide, using a fyke net of 30 m x 1.5 m and meshes of 8 and 10 mm. Simultaneously with the biological collections, temperature, salinity, pH, water transparency, and current speed data were obtained. The collections resulted in the capture of 36,873 fish representing 22 families and 52 species. Immature individuals abounded (63.8%), and among the adult specimens there was a larger number of females. The species Anchoa parva, Harengula clupeola, Genidens genidens, and Bairdiella ronchus, contributed to 84.9% of the total capture of fish, however the contribution in mass was of 55.2%, indicating a predominance of small individuals. A smaller number of fish and species seem to occupy the area in the period between August and December, in comparison to the period between February and July, when the larger aggregations appear, mainly of the species Anchoa parva, Harengula clupeola, Opisthonema oglinum, Genidens genidens, Diapterus rhombeus, and Bairdiella ronchus. The environmental factors, pH, water transparency, and rainfall seem to have an influence in the structure of the observed biological patterns.Key words: tidal creek, fishes, diversity, abundance, temporal variation. RESUMO Um estudo sobre a estrutura da comunidade de peixes de um rio de maréA comunidade de peixes em um rio de maré de mangue foi estudada em coletas mensais entre agosto de 1998 e julho de 1999 na baixa-mar e preamar de quadratura, utilizando-se uma rede fixa tipo "fyke" com 30 m x 1,5 m e malhas de 8 e 10 mm. Simultaneamente às coletas biológicas, foram registrados dados de temperatura, salinidade, pH, transparência da água e velocidade da corrente. As coletas resultaram na captura de 36.873 peixes, representando 22 famílias e 52 espécies. Predominaram indivíduos imaturos (63,8%) e as fêmeas, entre os adultos. As espécies Anchoa parva, Harengula clupeola, Genidens genidens e Bairdiella ronchus constituíram 84,9% da captura total de peixes, no entanto, a participação em peso foi de 55,2%, indicando o predomínio de indivíduos de pequeno porte. Um menor número de peixes e espécies parece ocupar a área no período entre agosto e dezembro, comparado ao período entre fevereiro e julho, quando aparecem os maiores agregados, principalmente das espécies Anchoa parva, Harengula clupeola, Opisthonema oglinum, Genidens genidens, Diapterus rhombeus e Bairdiella ronchus. O pH, a transparência da água e a pluviosidade parecem influenciar a estruturação dos padrões biológicos observados.Palavras-chave: rios de maré, peixes, diversidade, abundância, variabilidade temporal.
