Abundances of Zooplankton volumes, fish eggs and larvae were determined for 812 oceanographic stations on six survey cruises to the southern Brazilian continental shelf. Contour charts of Zooplankton volumes are presented. A marked seasonality on Zooplankton volumes and number of fish eggs and larvae was observed. The highest values were obtained during late spring and summer seasons and the lowest in the autumn. The mean values of Zooplankton volumes, eggs and larvae for different depth zones and subareas were presented. Major part of fish larvae were classified into 55 families. The most abundant group were those of family Engraulidae, Myctophidae and Gonostomatidae. The larvae of Clupeidae were abundant in the late-spring and summer cruises.
