2007年10月在南海北部设置13个断面(82个站位), 调查大型网采(孔径76um)砂壳纤毛虫的丰度、生物量和种丰富度。调查发现砂壳纤毛虫7属, 22种, 南海新纪录7种; 其中Tintinnopsis(拟铃虫)最多, 共10种, Codonellopsis(类铃虫)次之, 共6种。砂壳纤毛虫总丰度为0—41 768ind•m-3, 平均为(2 851-7 244)ind•m-3, 生物量为0—609.92ug•m-3(以碳含量计算,下同),平均为(42.75-110.80)ug•m-3; 76.83%站位的砂壳纤毛虫丰度低于1 000ind•m-3。砂壳纤毛虫生物量与丰度分布的总体趋势为近岸高且站位间差异大, 远洋低且站位间差异小。所采集种类集中分布于雷州半岛以东的近岸浅水区, 此区水文状况为高温低盐, 高叶绿素a浓度(Chl a); 不同种的分布规律不同, 多呈斑块状分布。各站位种的丰富度为0—12, 水平分布呈现近岸高远岸低的规律; 砂壳纤毛虫的丰度、生物量以及种丰富度与Chl a浓度均为正相关关系; Tintinnopsis schotti和Tintinnopsis radix为优势种。

Abundance, biomass and species richness of large tintinnids (>76um) in October 2007 were investigated over 82 stations along 13 sections in the northern South China Sea. Totally 22 species in seven genera were found, in which Tintinnopsis spp. was dominant in abundance. Seven species were recorded for the first time in the South China Sea. The abundance of tintinnids ranged from 0 to 41 768ind•m-3, with an average of (2 851-7 244)ind•m-3; their biomass ranged from 0 to 609.92ug•m-3(calculated by carbon content, the same below), with an average of (42.75-110.80)ug•m-3. Compared with those in the pelagic ocean, the abundance and biomass of tintinnids were higher in shallow coastal waters in the east of the Leizhou Peninsula, where the water was warmer, less salty and with higher Chl a. Most species distributed in patches. The species richness of all stations was from 0 to 12. The abundance, biomass and species richness of tintinnids were closely related to Chl a concentration. Tintinnopsis schotti and Tintinnopsis radix were dominant species.
