Abstract

Variations along the meridian 78°E between 8⁰N and 25⁰S, based on 43 zooplankton samples were studied. Fish larvae exhibited fluctuations in abundance (26 to 57 specimens/IOSN haul) in the three zones studied (8°N-5°S, 5°S-15°S and 15°S-23°S). Fish eggs showed variations within the zones, having a maximum of 1 to 5 in Zone B. While greater variations of 1 to 4 were shown in Zone B by the bivalve larvae, it was less in other zones. Marked variations among the anthozoan, cephalopod and sipunculoid larvae were not discernible in the different zones owing to their low occurrence.
