| Abstract: | Phytoplankton studies in Peter the Great Bay (Sea of Japan) revealed three species of the genus Pseudo-nitzschia H. Perag. in H. et M. Peragallo, namely, P. pungens (Grun. ex Cl.) Hasle; P. multiseries (Grun.) Hasle, and P. pseudodelicatissima Hasle. Mass blooms of P. pungens and P. multiseries were registered in Amurskii Bay in June 1992. The maximum density (11 million cell/liter) was registered at the water surface after heavy rainfall. A short-term outburst of the density of P. pseudodelicatissima (2.7 million cells/liter) was registered in Amurskii Bay in November 1997. We present morphological descriptions of all the species from the results of light and electron microscopy and discuss possible reasons favoring their mass development in Peter the Great Bay. |
