Souza, C.S.; Barreiro, A. S. & Mafalda Jr., P. 2010. Spatial and temporal patterns of Scaridae larvae (Pisces: Perciformes) in the northeast of Brazil in relation to oceanographic conditions. Braz. J. Aquat. Sci. Technol. 14(2): 1-11. ISSN 1808-7035. This work had as objective to study the distribution and abundance of the Scaridae larvae and to analyze the influence of oceanographic conditions (temperature and salinity), on the space and temporal distribution of larvae. Ichthyoplankton was collected during expeditions: Period 1 (August -October 1995), Period 2 (January -April 1997), Period 3 ( April -July 1998) and Period 4 ( September -December 2000), realized in the Northeast Exclusive Economic Zone. One specie (Cryptotomus roseus) and one genus (Sparisoma sp.) were identified. Sparisoma sp. was the most abundant genus (94% of the total), with higher abundance during all Periods. Cryptotomus roseus was the less abundant specie, representing 6% of the total identified larvae. Cryptotomus roseus presented larger distribution with the maximum density during period 3, between Maceió and Aracajú. Sparisoma sp. larvae were found mainly in oceanic stations and near São Pedro and São Paulo Archipelago.
