Abstract
Feeding habits of Stellifer rastrifer (Perciformes, Sciaenidae) at Guaratuba mangrove, Parana, Brazil, were studied from February 1996 to February 1997. It was observed that its diet was based on invertebrates, mainly Decapoda non-Brachyura and Polychaeta. In a smaller proportion there were plants, Copepoda, Gammaridea and Mollusca. The level of contribution of each food item changed according to the season and the individual size. Such plasticity in feeding behaviour was similar to that described to some fish populations from other estuaries, and could be an indicator of the high level of instability presented by this kind of ecosystem.
A alimentação do cangulo ou canguá, Stellifer rastrifer, foi estudada no manguezal da Baía de Guaratuba entre fevereiro 1996 e fevereiro 1997. Constatou-se que a dieta está baseada em invertebrados, sobretudo Decapoda Brachyura e Polychaeta. Secundariamente, registram-se vegetais superiores, Copepoda, Gammaridea e Mollusca. O grau de participação dos itens varia com a estação e o tamanho dos indivíduos. Tal plasticidade no hábito alimentar, também conhecida em outras populações de peixes estuarinos, pode ser considerada como mais um indicador do grau de instabilidade encontrado nestes ambientes.
