Composi??o e estrutura da comunidade de peixes de uma praia arenosa da Ilha do Frade, Vitória, Espírito Santo

摘要

The ichthyofauna of a sandy beach on Ilha do Frade, Vitória, Espírito Santo, was sampled monthly between May/2004 and April/2005. As many as 2,689 individuals were collected from 26 families and 45 Teleostei species, mainly juvenile forms. The Sciaenidae presented the highest number of species. The monthly collections showed that the most abundant species in number were Lutjanus synagris (Linnaeus, 1758), Archosargus rhomboidalis (Linnaeus, 1758), Eucinostomus lefroyi (Goode, 1874), and Paralonchurus brasiliensis (Steindachner, 1875); in terms of biomass, Cyclichthys spinosus (Linnaeus, 1758), A. rhomboidalis, E. lefroyi and L. synagris dominated. Number and biomass varied significantly (p<0.01) among months. Shannon-Wiener's Index (H') presented low monthly variation, not evidencing a seasonal tendency.
