• We studied on the age composition and circulii of the black croaker which were caught in the East China Sea. As to its age composition, numerous groups of the aged fish are found in the northern area, the less groups in the central area and moderate number of the groups in the southern area. The survival rate shows the value of 0.698 or 0.668. We could classify the scales into three types according to the circulii and their compositions differing in the fishing area, namely, percentage of A type circulii is 68% in the central or southern area each, B type is 63% in the northern area, and C type is moderate in every area. In the fish caught in northern area the growth rate is good and the number of circulii in L1 and L2 annual ring is less than those taken in the central and southern area.
