| Abstract: | Abundance, biomass and size structure of planktonic oligotrich ciliate were investigated in the shelf areas of East China Sea (25°~33°N, 120°~127°30'E) at six transects (E1-E6) during two cruises in autumn (11.19-12.23) 2006 and winter (2.22-3.11) 2007. Ciliate abundance and biomass ranged from 0 to 1795 ind./L and from 0 to 2.36 μg C/L, respectively, in autumn. Ciliate abundance and biomass were in the range of 0 to 22 695 ind./L and 0 to 10.87 μg C/L, respectively, in winter. In autumn, ciliate abundance and biomass in outer and middle shelf was greater than inner shelf water. However, in winter the middle shelf had more ciliates than outer and inner shelf. High water column integrated ciliate abundance distributed in the northern transect E2 and southern transect E5 near the outer shelf in autumn and in center area of northern transects in winter. Vertically, ciliates mainly occurred in the upper and middle layers in autumn and winter. Aloricate ciliates were dominant in the abundance in autumn and winter, but contribution of tintinnid to total biomass was higher than aloricate ciliate in autumn. Small ciliates (ESD 10~20 μm) accounted for 63% and 82% in abundance in autumn and winter, respectively. Through comparison with previous ciliate reports in East China Sea, ecological distribution of planktonic ciliates was found no distinct variation. |
