摘要：Horizontal and vertical distribution patterns and abundance of larval phosichthyids were investigated from oblique and depth-stratified towns off Southeastern brazilian waters, from São Tomé cape (41ºW.; 22ºS.) to São Sebastião island (45ºW.; 24ºS.).The sampling was performed during two cruises (January/2002 -summer; August/2002 -winter).Overall 538 larvae of Phosichthyidae were collected during summer and 158 in the winter.Three species, Pollichthys mauli, Vinciguerria nimbaria and Ichthyioccoccus sp.occurred in the area, but Ichthyioccoccus sp.was extremely rare represented by only one specimen, caught in the oceanic region during the summer.Geographically, larval were concentrated in the oceanic region, and vertically distributed mainly between the surface and 80 m depth in the summer and winter.Larvae were more abundant during the night, performing a diel vertical migration in the water column.The results suggest that the meandering and eddies of Brazil Current play important role on the transport and distribution patterns of larval phosichthyids over the oceanic and neritic area in the Southeastern Brazil.
