Abstract

A bloom of potentially toxic diatoms of the genus Pseudo-nitzschia was observed in October–November 2005 in the northeastern part of Amursky Bay in the vicinity of Vladivostok (northeastern Sea of Japan) at a salinity of 31–33.5‰ and a water temperature of 6–12°C. The most intense peak of Pseudo-nitzschia spp. cell density (with a mean value of 1428.9 thousand cells/liter), which was recorded in the second half of October after heavy rains, was mainly caused by the massive development of P. multistriata (67% of the total density) and P. calliantha (9%). A negative correlation was found between Pseudo-nitzschia spp. cell density and water salinity and NH4 concentration; a positive correlation was observed between diatom population density and water temperature.
