Phytoplankton in Ships' Ballast Waters in the Port of Vladivostok

摘要

The first results on the quantitative and qualitative composition of phytoplankton from ballast waters of the tanker Minotaur, which plies along the Russian—Chinese line between the ports of Vladivostok (Sea of Japan) and Longkou and Laizhou (YellowSea), are presented. From October 2007 to December 2009, 157 species of microalgae belonging to six divisions were recorded. The number of phytoplankton species in samples reached 45 and the density was 213 318 cells/1. Within the period of studies, tenspecies of potentially toxic microalgae and five species new to Peter the Great Bay, diatoms Cyclotella litoralis, Eucampia zodiacus f. cylindrocornis, Liolomapacificum, and Stephanopyxispalmeriana and dynoglagellate Prorocentrum cf. rhathymum, were found.
