【 摘 要 】

To examine the temporal patterns in the occurrence of a tropical ichthyofauna, fisheries-independent samples were collected between September 2003 and July 2004 from intertidal mangrove creeks in the Curuçá estuary, Pará, north Brazil. Juveniles occurred year-round with the most intense occurrence during the wet/dry transition season (Anchovia clupeoides, Cetengraulis edentulus, Rhinosardinia amazonica, Mugil sp.). The occurrence of Colomesus psittacus and Anchoa hepsetus was continuous. Sciades herzbergii displayed two peaks (wet and dry season) while Cathorops sp. peaked only in the wet season. The continuous presence of juveniles in the tropical mangroves suggested that the fisheries management should be based on large no-take areas rather than closed seasons.
