2009年冬、夏季对南海北方海域浮游纤毛虫的丰度和生物量进行了调查。冬季纤毛虫平均丰度为（486±484）ind/L，夏季为（809±1008）ind/L。冬季纤毛虫的平均生物量为（2.84±3.26）μ g C/L，夏季为（1.96±3.80）μg C/L。两个季节纤毛虫的深度加权平均丰度和生物量均由沿岸向外海递减，且沿着样带S1高于样带S2。冬季纤毛虫在次表层聚集。夏季纤毛虫的丰度和生物量通常在表层或中层较高，但有时在近海站纤毛虫位于底层附近。在冬季，锡类昆虫很少被发现，而在夏季，锡类昆虫被鉴定为14属22种。冬、夏季纤毛虫丰度分别占总丰度的1.7%和22.6%。
We investigated the abundance and biomass of planktonic ciliates in the northern South China Sea in winter and summer, 2009. The average abundance of ciliates in the winter and summer were(486±484) and(809±1008) ind/L, respectively. The average biomass of ciliates in winter and summer were(2.84±3.26) and(1.96±3.80) μg C/L, respectively. The depth-weighted average ciliate abundance and biomass decreased from coastal areas to off-shore areas in both seasons, and were higher along Transects S1 than Transect S2. Ciliates tended to accumulate in the sub-surface layers in winter. Ciliate abundance and biomass were usually higher in the surface or middle layers in summer, although sometimes ciliates were located near the bottom layers in the off-shore stations. Tintinnids were rarely detected in winter, while 22 tintinnid species of 14 genera were identified in summer. Tintinnids occupied 1.7% and 22.6% of the total ciliate abundance in winter and summer, respectively.
