Among the 31 species of phytoplankton identified, the cold - water species rank highest in proportion. The cell number of phytoplankton averaged 162. 5×104 cells/m3 in the bay. The most dominant species are Chaetoceros socialis Lauder, Rhizosolenia. alata f. inermis (Castr. ) Hustedt and Biddulphia striatas Karsten. The former species mainly appeared in the bay and the latter two species aggregated at the bay mounth.展开更多

The results indicate that the specific composition of phytoplankton clearly shows their ecological characteristics. That is the community mainly composed of cold-water species and neritic-eurythermal species. The dominant species altered with seasonal variation, their number showed the high-peak in the austral summer and the abundance of phytoplankton in each month mainly depended upon the dominant species. The distribution of phytoplankton is influenced by many environmental factors. Among them the hours of sunshine are the main factor.展开更多
