Abstract

The composition of species, quantity, biomass, indexes of the Shannon (H), Pielou (e), coefficient of Chekanovsky-Sőrensen (Ks) of diatom communities in peryphyton of experimental plates in extremely-eutrophic Gold Horn Bay and in temperately Rynda Bay are studied in a summer–autumn 2000. Ninety-four taxa of diatoms were found with predominance of Bacillariophyceae (60.6%). In Gold Horn 45 taxa were revealed, Rynda Bay – 60; 26 taxa are common for both bays. Eight taxa of diatoms: Amphora caroliniana Giffen, Ardissonea crystallina (C. Agardh) Grunow, Falcula media var. subsalina Proschk.-Lavr., Neosynedra provincialis (Grunow) Williams et Round, Gyrosigma tenuissimum (W. Sm.) Griff, et Henfr., Nitzschia hybrida f. hyaline Proschk.-Lavr., Synedra toxoneides (Ǿstrup) Hust. and Pleurosigma clevei Grunow. are reported for Russian waters of the Sea of Japan for the first time. Species-indicators of organic contamination of waters were discovered: Gold Horn Bay prevailed α- and β-mesosaprobionts, Rynda Bay – β-mesosaprobionts. Quantity and biomass of diatoms of Gold Horn Bay is 1,5 times higher due to planktonic species settling on substrate, as compared to a substrate of Rynda Bay, were benthic and bentho-planktonic diatoms prevailed.
