| Abstract: | The seasonal changes of abundance of populations of Acartia bificlosa and A. pacifica in the water column and of their eggs recovered from the bottom sediment in Jiaozhou Bay are described. The density of eggs in the sea bottom was the highest shortly before the disappearance of copepods from the plankton; the numbers of eggs then gradually decreased until the appearance of the next planktonic population. Resting eggs obtained from sea-bottom sediment were hatched at different temperature and salinity conditions in the laboratory. A wide range of salinity, from 5 to 50 for A. bifilosa and from 5 to 65 for A. pacifica was favourable for hatching. Eggs failed to hatch within the sediment mud. Temperature seems to be the main factor that influencing the production and hatching of- resting eggs. |
