| 摘 要： | 2000年7月至2001年7月的周年调查结果表明,粤东柘林湾浮游桡足类29属57种,其中,强额拟哲水蚤Paracalanus crassirostris和短角长腹剑水蚤Oithona brevicornis为优势种,合计占浮游桡足类总个体数的66.7%.柘林湾是一个浮游桡足类相对丰富的海湾,年均总个体数达5.4×103ind.·m-3.浮游桡足类的种类数和总个体数均表现为湾外大于湾内的平面分布格局,周年变化基本上为单峰型,高峰期位于5~10月,最低谷位于冬季1月。

| 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. |
