报道了2009年夏季北部湾A、B两个断面浮游纤毛虫的丰度和生物量。纤毛虫的平均丰度为521±369个·L-1,平均生物量(以碳为单位)为0.63±0.54μg·L-1。表层纤毛虫丰度和生物量的水平分布格局基本一致,高值主要位于湾的北部近岸、西南部近岸及湾中部A5站。两个断面纤毛虫丰度和生物量的垂直分布特点不同,纤毛虫在A断面水体中的垂直分布较均匀,在B断面主要分布在15m层以浅。共鉴定出砂壳纤毛虫13属20种,其中较为优势的种类为原始筒壳虫Tintinnidium primitivum、薄壳真铃虫Eutintinnus tenuis、三亚条纹虫Rhabdonella sanyahensis、未定种砂壳纤毛虫和斯氏拟铃虫Tintinnopsis schotti,且表现出不同的水平分布和垂直分布规律。

We investigated the abundance and biomass of planktonic ciliates along two intersecting transects (Transects A and B) in the Beibu Gulf during summer 2009. The average abundance of ciliates was 521±369 ind·L-1, the average biomass was 0.63±0.54 μg·L-1. Ciliate abundance and biomass in the surface layer were higher in the coastal waters and at Station A5 (located in the central gulf). Ciliate abundance and biomass were uniformly distributed vertically in the water column along Transect A, while ciliates tended to accumulate in the upper 15 m along Transect B. Twenty tintinnid species of 13 genera were identified. The most dominant species were Tintinnidium primitivum, Eutintinnus tenuis, Rhabdonella sanyahensis, tintinnid sp., and Tintinnopsis schotti, and they exhibited distinct patterns along the two transects.
