| 摘 要： | Paracalanus parvus,Paracalanus crassirostris,and Acartia bifilosa are dominant and widely distributed in the Bohai Sea,and comprise an important part of zooplankton in terms of biomass as well as production rate.In order to understand their seasonal distribution and population dynamics,their stage-specific abundance in different months of the year were analyzed based on the never analyzed yet samples collected in 1959.The three species showed clear and remarkable seasonal variation in abundance,which maximized in spring and summer,when they formed high biomass patches or concentrations in the nearshore area.For Paracalanus parvus,two peaks were observed in the annual circle,one in June and the other in September,For Paracalanus crassirostris,one peak occurred in summer and a small one in December.The seasonal pattern of Acartia bifilosa was different in different regions.In Bohai Bay it had a two-peak pattern,with the first large peak occurring in May and the second one in October.In Laizhou Bay,a winter peak in December and January could be observed besides the spring one.The number of generations during the reproductive season for the three species was estimated based on the annual cycle in abundance and ambient temperature.

| Abstract: | Paracalanus parvus, Paracalanus crassirostris, andAcartia bifilosa are dominant and widely distributed in the Bohai Sea, and comprise and important part of zooplankton in terms of biomass
as well as production rate. In order to understand their seasonal distribution and population dynamics, their stage-specific
abundance in different months of the year were analyzed based on the never analyzed yet samples collected in 1959. The three
species showed clear and remarkable seasonal variation in abundance, which maximized in spring and summer, when they formed
high biomass patches or concentrations in the nearshore area. ForParacalanus parvus, two peaks were observed in the annual circle, one in June and the other in September. ForParacalanus crassirostris, one peak occurred in summer and a small one in December. The seasonal pattern ofAcartia bifilosa was different in different in different regions. In Bohai Bay it had a two-peak pattern, with the first large peak occurring
in May and the second one in October. In Laizhou Bay, a winter peak in December and January could be observed besides the
spring one. The number of generations during the reproductive season for the three species was estimated based on the annual
cycle in abundance and ambient temperature.
