Abstract
Based on the data of four oceanographic censuses in the Quanzhou Bay in 2001~2002,this paper discussed the species composition, distribution of abundance and the main species. The results show that totally 34 species of ichthyoplankton belonging to 14Family, 21Genus, were observed in Quanzhou Bay. Eggs and larvae and juveniles attain the maximum catch in Spring (May) ; most of the eggs are species of Engraulidae (34.2%), most of larvae and juveniles are species of Sillaginidae ((61.8%)). The distribution of the highest eggs and larvae and juveniles apper in station nine. It is show that the main spawning season is in May.
