【Abstract】 Zhelin Bay and its adjacent seawater were surveyed from July, 2000 to July, 2001. 57 species of planktonic copepod were found, among which Paracalanus crassirostris and Oithona brevicornis were the most dominant species, accounting for 66.7 percents of total copepod individuals. With annual average of total copepod individuals up to 5.4 ×103 ind.·m-3, copepods were abundant in Zhelin Bay. The horizontal distributions of species numbers and total individuals of planktonic copepods in the investigated area showed a general increase from inner bay to the outside of it. During the investigation, annual variations of them appeared in a single-peak, accompanied by the peak period from May to October and the minimum in January.更多还原
