摘要
A preliminary identification has been made of 35 species of the zooplankton in the Great Wall Bay and its adjacent waters,Antarctica. The dominant species in the investigated area are Calanus propinquus, Calanoides acutus, Metrdia gerlachei and the larvae of antarctic krill.The results indicated that the zooplankton in the investigated waters were simple in species number, which conforms to the general pattern of the distribution of the zooplankton in antarctic waters.The total biomass and number of individuals of the zooplankton in the investigated waters showed obvious seasonal variation. In summer there were Calaninioides acutus and the larvae of antarctic krill; in winter there were Metrdia gerlacher, Calanus propinquus, Oithon similis, O. frigda and the larvae of antarctic krill. The quantity of Copepoda occupied a considerable proportion in each month. The water temperature is an important factor in controling the biomass of zooplankton.
