The spatial distribution of fish larvae is not homogeneous, in fact it is aggregate. The patterns and variations of distribution and abundance of fish larvae depend on interaction between biotic and abiotic processes. The knowledge of fish larvae dynamics related with these processes is fundamental to understand their biology and ecology. The main purpose of this work is to investigate and describe the distribution and the relation between the fish larvae of Paralichthyidae family and the oceanographic conditions of the Brazilian Southeast Continental Shelf. The fish larvae were obtained during two oceanographic cruises, between São Tomé Cape (RJ) Sebastião Island (SP), from coast to the 200 m isobath. Oblique hauls were done using a bongo net with 333 and 505 mm mesh size. These samples are part of the project "Dynamics of the Ecosystems on the West of the South Atlantic Shelf". In laboratory the larvae were totally sorted and it will be identified to species level. The abundance and frequency of occurrence will be calculated. Statistical analysis will be done to verify the differences in larval abundance between regions, seasons and oceanographic data. These results will be effective in describe the distribution of Paralichthyidae fish larvae in relation to the oceanographic conditions in this region.
