| Abstract: | Phytoplankton surveys were conducted at 12 stations in Sishili Bay during August, October, December 2009 and March 2010. Three classes including 45 genera and 73 species were identified from the samples. Among them, 46 species were Bacillariphyta; 24 species were Dinophyta; 3 species were Heterokontophyta. Diatoms dominated the phytoplankton community in species richness and biomass. Results presented significant seasonal variations in terms of species richness and cell abundance: species richness was 57 in summer, 40 in autumn, 36 in spring and 21 in winter, respectively; and the cell abundance gradient was summer (8.14×104 cells/dm3) > spring (2.45×104 cells/dm3) > autum (0.46×104 cells/dm3) > winter (0.28×104 cells/dm3). Species including Chattonella marina, Pseudo-nitzschia delicatissima and Paralia sulcata etc. dominated the Sishili Bay in our study. The phytoplankton community had a low biodiversity index in this research. The cell abundance of Chattonella marina was at the threshold value of harmful algal blooming in summer of 2009. Moreover, the eutrophic indicator species Paralia sulcata had a high cell abundance in most stations during the surveys, which indicated that the bay was in a worsening status of water quality. |
