The distribution and seasonal dynamics of Centropages abdominalis and C. tenuiremis (Copepoda) in Amursky Bay (Sea of Japan) were studied from May through November 1991. C. abdominalis occurred in the plankton from May through August and in November, with a peak density of more than 40 000 ind./m³ in June at a temperature of 15-18°C. C. tenuiremis occurred from late June through November, with maximum total density of 6900 ind./m³ in August at 23°C. During the observation period, the distribution of species in the bay was irregular due to the hydrological regime and sanitary state of waters in the bay.

Key words: zooplankton, C. abdominalis, C. tenuiremis, distribution, seasonal dynamics, Amursky Bay, Sea of Japan
