The seasonal distribution pattern of zooplankton were studied on the basis of the zooplankton samples collected from 9 stations in Jinhae Bay in May, August, November and February, 2001 to 2002. A total of 31 species in 37 taxa was occurred in Jinhae Bay. Copepods were pyedominant through fall to spring and cladecerans in summer. There aye high spatio-temporal fluctuations in the zooplankton abundance in a range of 27 to 28,221 indiv. $m^{-3}$. Of these, an neritic species, Acartia omorri and Oentropages abdominals were predominent in february; Palaealanus parvus s. 1 in November; Penilia avirostris in August. Species diversity was low in the northwestern regims where anoxia layer is occurred in summer, while in the other seasons there was no a great difference between stations. It indicates that the distribution pattern of zooplankton may be seasonally strongly affected by a mechanism of hypoxia formation in Jinhae Bay.
