Abstract: 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.

Key words: planktonic ciliate, abundance, biomass, Beibu Gulf
