摘　　要：在使用表层海水作养殖水的杂色鲍(Haliotisdiversicolor)养成池,整个养成阶段共检测到浮游纤毛虫33种,其中寡毛目(Oligotrichida)的种类最多,为14种。在一个使用沙井水作养殖水的杂色鲍养成池周年研究中,共观察到浮游纤毛虫24种。2类养成池的纤毛虫优势种都是尾丝虫(Uronemasp.)、钟虫(Vorticellasp.)和具沟急游虫(Strombidiumsulcatum)。虽然后者养殖用水为沙井水,但养殖密度较大,水体交换量稍低,养殖水体中有机质含量高,嗜污性纤毛虫得以大量繁殖,其密度较前者高一倍。在养殖用水取水海区———红海湾近岸表层海水中,共检测到浮游纤毛虫27种,其中砂壳亚目(Tintinnina)纤毛虫16种。受水环境中二氧化碳浓度变化影响,养成池与取水海区砂壳虫的种类组成和密度有较大区别。Totally 33 species of ciliates were found in the culture ponds with surface seawater, and 24 in the culture ponds with sand-filtrated water. The dominant ciliates were Uronema sp.,Vorticella sp. and Strobidium sulcatum. The latter, with water from the well of tideland, had the higher density of plankton ciliates than the former due to the higher culture density and lower water exchange which caused high organic matter content in the water and rapid propagation of ciliates indulging in pollutants. The species composition and density of plankton ciliates in the surface water of the Honghai Bay were also studied. Totally 27 species of ciliates, belonging to 3 classes, 6 orders and 18 genera, were found. 16 species of ciliates were under Tintinnina. Affected by the concentration change of CO_2 in the water environment, the density and species of Tintinnina in the both culture ponds were distinguished from those in the Honghai Bay.
