摘要
2004年7~8月在台湾海峡南部的5个站位,用稀释法研究了浮游植物的生长率,微型浮游动物对浮游植物的摄食率及其生产力.微型浮游动物主要为无壳纤毛虫,尤其是急游虫类和侠盗虫类.浮游植物的生长率为0.52~0.72/d,浮游动物的摄食率为0.45~1.33/d,相当于每天掇食浮游植物现存量的36%~74%和初级生产力的88%~141%.微型浮游动物的次级生产力(MP2^0)为初级生产力的28.5%~58.4%.表明微型浮游动物在台湾海峡夏季海洋生态系统的能量流动中发挥着重要的作用.
Growth rates of phytoplankton and mortality rates duo to microzooplankton grazing were estimated using a dilution method at five stations in the South Taiwan strait from July 29 to 1 August 2004, microzooplankton secondary production (MP2^0) and microzooplankton total production (MPtot) as a percentage of daily primary production were calculated. Microzooplankton was mainly composed of aloricate ciliates, especially Strornbidium spp. and Strobilidiurn spp. Phytoplankton growth rates were 0.52 - 0.72/d, mortality rates were 0.45 - 1.33/d. Microzooplankton comsumes 36% - 74% of the phytoplankton biomass or 88% - 141% of the primary production per day. Microzooplankton secondary production (MP2^0) as a percentage of daily primary production was 28.5% -58.4%. These results indicated that microzooplamkton palyeds an important role in energy flux in marine ecosystem of Taiwan Strait in summer.
