Marine Ecological Journal| Резюме: | Taxonomic composition, numerical density and biomass in areas of the seaports of Novorossiysk and Tuapse have been analyzed. Microplanktonic algae of 145 taxa; in the Novorossiysk Bay – 131 including 7 alien species, in the port of Tuapse – 104 (2) properly were identified. The species of diatom algae (potentially toxic and causing harmful algal bloom) were dominant, composed the most part of density and biomass of phytoplankton of the port areas (50–80%), euglenophytes and cyanophytes – 8–10%. The role of primnesiophytes essentially E. huxleyi was appreciable in the number of phytoplankton of the open waters (21–47%). The contribution of dinoflagellates was significant only in a total biomass of phytoplankton (26–34%). The decrease of density of phytoplankton in 2 – 5 times, biomass – 3–4 times in the seaports of Novorossiysk and Tuapse is recorded during the last years in water areas. Most polluted port of Tuapse was characterised by lower level of development of phytoplankton (~ 3 times low, than in the Novorossiysk Bay). |
