Resumo: | The stomach contents of 1480 specimens of 5 large pelagic fish (Acanthocybium solandri, Coryphaena hippurus, Elagatis bipinnulata, Thunnus albacares e Thunnus atlanticus) captured surrounding the Saint Peter and Saint Paul Archipelago were counted and weighed to describe the feeding habits and dietary overlap. They identified 71 items of prey, grouped into five taxonomic groups (Cnidaria, Crustacea, Mollusca, Teleostei and Tunicata). The teleost were the most abundant prey in the stomachs. The teleost were the main food item in the diet of A. solandri and T. atlanticus; the species of Exocoetidae Family were the most important prey in the diet of C. hippurus; Crustacean Stomatopoda was the most important item in the feed E. bipinnulata and flying fish, Cheilopogon cyanopterus, was the prey with greater emphasis on T. albacares diet. The five species have high degree of specialization and trophic level, being considered experts species and top predators. According to the contributions of prey species in the diets of most trophic overlaps were low and only two were considered high and significant, the main rate of consumption of prey, specimens of Exocoetidade, the important factor for dissimilarity diets. Finally, all five species were considered top predators, with trophic level above 4. Thus, this set of species, can be considered functionally frequent and important in the structure and dynamics of the food chain of the Archipelago. |

Foram identificados 71 itens de presas, agrupados em cinco grupos taxonômicos (Cnidaria, Crustacea, Mollusca, Teleostei e Tunicata). Os teleósteos foram a presas mais abundante nos estômagos. Os teleósteos foram o principal item alimentar na dieta do A. solandri e do T. atlanticus; representantes da família Exocoetidae foram as presas mais importante na dieta do C. hippurus; o crustáceo Stomatopoda foi o item de maior importância na alimentação do E. bipinnulata e o peixe-voador, Cheilopogon cyanopterus, foi a presa com maior destaque na dieta do T. albacares. As cinco espécies possuem alto grau de especialização e nível trófico, sendo considerados espécies especialistas e predadores de topo. Segundo as contribuições de presas nas dietas das espécies a maioria das sobreposições tróficas foram baixas e apenas duas foram consideradas altas e significativas, sendo a taxa de consumo da principal presa, exemplares da Família Exocoetidade, o fator importante para dissimilaridade das dietas. Por fim, todas as cincos espécies foram consideradas predadores de topo, com nível trófico acima de 4. Assim, este conjunto de espécies, podem ser consideradas funcionalmente frequentes e importantes na estrutura e dinâmica da cadeia alimentar do Arquipélago.Submitted by Mario BC (mario@bc.ufrpe.br) on 2017-10-17T13:23:10Z No. of bitstreams: 1 Fernanda Virginia Albuquerque da Silva.pdf: 1221267 bytes, checksum: b5fb1a47cac14fd84deab590a99b289f (MD5)Made available in DSpace on 2017-10-17T13:23:10Z (GMT).
