“…Mangrove prop roots and pneumatophores provide small juvenile fishes with an architecturally complex substratum that affords maximum food availability and minimizes the risk of predation (Laegdsgaard & Johnson, ; Vaslet et al ., ). Habitat structure has also been shown to influence the benthic faunal community of vegetated areas, which are important environments for numerous species of epiphytic fauna and flora that form temporary feeding areas for juvenile fishes from adjacent ecosystems (Pimentel & Joyeux, ; Freitas et al ., ).…”

The differences between fish assemblages in three microhabitat types, in relation to vegetation and sediment characteristics of a hypersaline estuary located in an semi-arid zone in north-eastern Brazil, were investigated. Fishes were collected using a beach seine during the rainy and dry seasons in 2012. A total of 78 species were recorded, with the most common families being Gerreidae, Lutjanidae and Tetraodontidae. The majority of species were represented by juveniles, with Eucinostomus argenteus, Ulaema lefroyi and Sphoeroides greeleyi being the dominant species. The fish assemblage structures differed significantly among microhabitat types, with the narrow intertidal flat adjacent to the mangrove fringe supporting the most diverse fish fauna. In addition, only 27 species were common to all of the microhabitats. The results support the hypothesis that hypersaline estuaries serve as important nursery areas for various reef fish species, due to the structural complexity provided by their macroalgae beds and mangroves.

“…Like several snapper species (Rojas and Chiappa 2002, Santamaría et al 2003, Rojas et al 2004, Guevara et al 2007, Oliveira et al 2011, it was found that as individuals of this species increase in size they incorporate a greater quantity of fi sh in their diet, because they acquire greater abilities to hunt prey with greater mobility such as fi sh (SaucedoLozano 1999, Santamaría et al 2003, Yan et al 2012). This strategy has been identifi ed as a potential strategy of predators to reduce competition and increase the coexistence of competitors (Zaret and Rand 1971, Ross 1986, Platell and Potter 2001, Navia et al 2007.…”

Variation of feeding habits of Lutjanus peru (Actinopterygii: Perciformes: Lutjanidae) caught in two regions of the Gulf of California, Mexico. Acta Ichthyol. Piscat. 46 (2): 97-108.Background. The Pacifi c red snapper, Lutjanus peru (Nichols et Murphy, 1922), is one of the most exploited species by artisanal fi sheries in Mexico, where it is valued due to its high catch rates and economic value. This study investigated the feeding habits of L. peru in two ecosystems of the southern Gulf of California with contrasting physical and oceanographic conditions. Feeding habits were compared by sex (male or female), size (juvenile or adult), and season (cold or warm), in order to determine whether this species plays the same trophic role in the two ecosystems. Materials and methods. Samples were obtained from the northern Sinaloa coast (SIN region) and south-eastern Baja California Sur coast (BCS region). Percentages by number, weight, and frequency of each food category were determined, and the index of relative importance (%IRI) was calculated to defi ne the main food categories. Diet breadth and diet similarity between sexes, sizes and among seasons were also calculated. Results. A total of 182 stomachs from the SIN region were analysed and 32 prey items from 15 families, 18 genera, and 25 species were identifi ed. According to the index of relative importance (IRI), the most important prey items were the shrimp, Penaeus californiensis (73%); the ostracods, Myodocopida gen spp. (10%); and the squid, Loligo spp. (5%). A total of 233 stomachs from BCS were analysed and 31 prey items from 17 families, 19 genera, and 26 species were identifi ed. The most important prey items according to the IRI were the red pelagic crab, Pleuroncodes planipes (42%); the ostracods, Myodocopida gen spp. (28%); and the shrimp, Penaeus californiensis (20%). Signifi cant differences were identifi ed in the trophic spectra by region, size and season. There were no signifi cant differences by sex. Conclusion. Lutjanus peru displayed a specialist trophic behaviour, with differential utilization of the trophic niche and adequate food resource distribution.

“…Suctionfeeding modes involve a rapid expansion of the buccal cavity, followed or not by jaw protusion, a feature that is observed in benthic invertebrate feeders (Eugerres brasilianus), piscivores (C. undecimalis) or macrocarnivores (L. synagris) (Wainwhright et al, 2006;Freitas et al, 2011;VasconcelosFilho et al, 2011). Also in Group 2 are grouped species of Carangidae: C latus, Oligoplites saurus and Trachinotus goodei, which have characteristics such as a high degree of lateral flattening and slender caudal peduncles, indicative of good swimmers that inhabit the mid-water column.…”

Ecomorphology and resource use by dominant species of tropical estuarine juvenile fishes

et al. 2015

Eleven ecomorphological attributes and diet of seventeen juvenile fish species were examined to test the hypothesis that morphological patterns determine resource uses in estuarine habitats. Species were separated according to the apparatus to food capture and habitat use (benthic or pelagic) in three different groups: (1) a group with depressed fish body, strong caudal peduncle and enlarged pectoral fins; (2) a second group laterally flattened with a wide protruding mouth, and (3) a third group strongly flattened with small pectorals fins. The following six trophic groups were organized based on prey categories: Zooplanktivores, Benthivores, Omnivores, Detritivores, Macrocarnivores and Insectivores. Significant results (PERMANOVA) between ecomorphological indices and habitat and between ecomorphological indices and trophic groups were found. These data indicate that similarity of ecomorphological forms, which minimize the influence of environment and partitioning of food, would help facilitate the co-existence of these fish when they are abundant in this tropical estuary.Onze atributos ecomorfológicos e a dieta de dezessete espécies de peixes juvenis foram examinados para testar a hipótese de que os padrões morfológicos determinam a utilização dos recursos em habitats estuarinos. As espécies foram separadas de acordo com o modo de captura do alimento e uso do habitat (bentônicos ou pelágicos) em três grupos distintos: (1) um grupo de peixes depressiformes, com forte pedúnculo caudal e nadadeiras peitorais alargadas; (2) um segundo grupo, compressiforme, com ampla boca protrusível, e (3) um terceiro grupo, fortemente achatado e com pequenas nadadeiras peitorais. Seis grupos tróficos foram organizados com base nas categorias de presas: Zooplanctívoros, Bentívoros, Omnívoros, Detritívoros, Macrocarnívoros e Insetívoros. Foram encontrados resultados significativos (PERMANOVA) entre os índices ecomorfológicos e o habitat e entre os índices ecomorfológicos e os grupos tróficos. Estes dados indicam que a similaridade ecomorfológica, que reflete o ambiente e o tipo de alimento consumido, facilitaria a coexistência desses peixes quando estes são abundantes neste estuário tropical.
