【Abstract】 In terms of data analyses of the occurrence period and distribution of the eggs and larvae of the red bigeye Priacanthus macrocanthus C. & V., collected from waters of the northern part of South China Sea during March-December, 1973, it may be assured that the spawning season of the fish is April-August, and the spawning ground is basically distributed along isobaths of the waters. In April-June the spawning ground may be divided into three zones, namely, those with water depths of 40-60m, 70-100m, 150-200m, respectively. In July-August, range of the spawning ground is in deeper areas with water depths of 60-90m and 100-200m, respectively. Larvae are mostly distributed in the long-shore neritic waters 40-60m deep; some are in the waters about 100m deep. Water temperature of the surface layer of the spawning ground is 24.38-29.98℃, salinity 31.51-34.58‰.
