摘要:
于 2007 年 1—12 月在胶州湾搭载“创新号”考察船完成了 12 个航次的浮游纤毛虫丰度和生物量调查。结果表明, 胶州湾纤毛虫丰度的范围为 41—31077ind/L, 生物量范围为 0.06—99.37μg C/L。表层纤毛虫平均丰度于 6 月达到全年最高值(6065ind/L), 12 月为最低值(843ind/L); 平均生物量8 月达全年最高值(18.5μg C/L), 6 月为最低值(0.6μg C/L)。除 6 月和 8 月外, 湾内站位纤毛虫的平均丰度比湾外的高。砂壳纤毛虫种数于 8 月达到最高值(25 种), 1 月种数最少(6 种)。砂壳纤毛虫丰度 在纤毛虫丰度中的比例全年平均为 25%, 分别于 1 月和 8 月达到最低(8%)和最高值(57%)。 断面资料显示, 纤毛虫的分布表层高于底层。表层砂壳纤毛虫生物量及表层纤毛虫的生物量均与表层温度呈极显著正相关, 与盐度呈极显著负相关; 表层砂壳纤毛虫的生物量及表层纤毛虫生物量与Chl.a浓度都没有明显的相关性。

Abstract:
Abundance and biomass of planktonic ciliates were surveyed in the Jiaozhou Bay on 12 cruises from January to December in 2007. Ciliate abundance ranged from 41ind/L (St. D5 in July) to 31077ind/L (St. D7 in June) and its biomass ranged from 0.06μg C/L (St. D6 in May) to 99.37μg C/L (St. Y1 in May). Average ciliate abundance in surface layer of all stations was highest (6065ind/L) in June and lowest (843ind/L) in December. Average ciliate biomass in surface layer of all stations was highest (18.5μg C/L) in August and lowest (0.6μg C/L) in June. Ciliate abundance in the inner Jiaozhou Bay tended to be greater than in the outer Bay except in June and August. Species richness of tintinnids was highest (25) in August while lowest (6) in January. Tintinnid accounted for 8%—57% (on average 25%) of total ciliate abundance. Furthermore, more ciliates appeared in the surface layer than in the bottom layer. Biomass of both tintinnids and total ciliates were significantly correlated with temperature, salinity but not with Chl.a concentration.
