Abstract:

 Abundance, biomass and species richness of large tintinnids (>76um) in October 2007 were investigated over 82 stations along 13 sections in the northern South China Sea. Totally 22 species in seven genera were found, in which Tintinnopsis spp. was dominant in abundance. Seven species were recorded for the first time in the South China Sea. The abundance of tintinnids ranged from 0 to 41 768ind•m-3, with an average of (2 851-7 244)ind•m-3; their biomass ranged from 0 to 609.92ug•m-3(calculated by carbon content, the same below), with an average of (42.75-110.80)ug•m-3. Compared with those in the pelagic ocean, the abundance and biomass of tintinnids were higher in shallow coastal waters in the east of the Leizhou Peninsula, where the water was warmer, less salty and with higher Chl a. Most species distributed in patches. The species richness of all stations was from 0 to 12. The abundance, biomass and species richness of tintinnids were closely related to Chl a concentration. Tintinnopsis schotti and Tintinnopsis radix were dominant species.

Key words: tintinnids, abundance, biomass, horizontal distribution, northern South China Sea
