Abstract: The surveys of fish eggs， larvae and juveniles were canied out in Zhao’an Bay of Fujian during spring ( 0ctober，2012 ) and autumn ( May，2014). The compositions of fish eggs，larvae and juveniles，as well as quantity of temporal-spatial distribution in Zhao’an Bay were studied. The results showed that 7 species of fish eggs，7 species of larvae and juveniles had been indentified，belonging to 10 genera, 10 families.In autumn，a total of 31 fish eggs and 47 larvae and juveniles were collected，which intensive areas were at north side of West Island in bay mouth. In spring，a total of 662 fish eggs and 69 larvae and juveniles were collected， which intensive areas were at north - central waters and west side of West Island. The dominant species were Labridae sp.，Omobranchus elegans in autumn， while which were Nibea albiiora，Lutjanus erythropterus and Omobranchus elegans in spring. Compared with the data of Dongshan Bay， the mean densities of fish eggs were obviously greater，while the mean densities of fish larvae and juveniles were slightly lower in spring. The quantity of fish eggs，larvae and juveniles in the two bays were both at low level in autumn，which indicated spawning season of two bays was the same in spring.
