| Resumo: |
Despite its importance, most ichthyoplankton studies in the South-Southeastern coast of Brazil, have been accomplished on the continental shelf. Regarding the beach environment, recognized as a nursery, little is known about the ichthyoplankton. We analyzed 288 samples collected with a 18 by 2 m seine net, 1 mm mesh and a conical plankton net, with a mesh of 300 mum and a 60 cm mouth. Eucinostomus argenteus comprised 78 % of the larvae and juveniles caught in the samples. The occurrence of gerreids was strongly concentrated in the summer, while the Menticirrhus littoralis, Menticirrhus americanus and Umbrina coroides were present during all seasons. M.littoralis was most abundant during spring, while M. americanus and U. coroides dominated during winter. For all species, the largest captures occurred during low tide. Environmental preferences are indicated in the principal component analysis, with the larvae and juveniles of E. argenteus and E. gula positively correlated with smaller waves and smaller morphodynamism, whereas M. americanus, U. coroides and M. furnieri seem to prefer periods with lower temperatures and larger morphodynamism.
