The ciliate Mesodinium rubrum Lohmann 1908 (= Myrionecta rubra Jankowski 1976) is an important phototrophic organismin the Gdańsk Basin. In June 2002 the vertical distribution and size structure of the M. rubrum population were studied. Its presence was generally observed in the whole water column (one exception was the anoxic near-bottom zone in the Gdańsk Deep) at all stations studied. Maximum abundance (18 300 cells dm−3) was recorded at 26 m depth at the station located in the inner Gulf of Gdańsk. Analysis of the size structure of the counted organisms demonstrated the co-existence of small and large cells of M. rubrum in the upper layer of the water column and a gradual increase with depth of the prevalence of large specimens. This shows that at least two forms of M. rubrum exist in the region studied. Deep migrations are probably undertaken only by relatively large organisms.

Ciliates constitute an important trophic link in aquatic environments, because they are essential food sources for zooplankton and fish. In this study, the spatial differences in abundance and composition of ciliate communities in relation to varying water salinity were investigated. The study was conducted in the large, brackish, eutrophic lakes Gardno and Łebsko. In the studied lakes, no significant differences among ciliate communities were identified among sampling sites. Ciliate communities in Lake Łebsko were characterized by a high contribution of tintinnids, with mean values at particular sites between 32% and 36%. In Lake Gardno, where salinity was lower, the importance of tintinnid ciliates increased after a marine water intrusion into the lake. In both lakes, the importance of tintinnids in ciliate communities was higher than in adjacent fresh and marine waters. Shortly after wind-driven intrusions of marine waters (backwaters), the marine and brackish mixotrophic ciliate Mesodinium rubrum was observed in both lakes. Once, in the eastern part of Lake Łebsko, Mesodinium major (= Mesodinium rubrum forma major) was observed after a strong backwater when salinity reached 5.4 PSU.

Diurnal changes in the structure of the ciliate community in surface waters were studied in the aquaculture area of Dapeng’ao cove, China. Two periods of heavy rainfall occurred during the study period, intensifying water column stratification and influencing the water’s properties. A total of 21 ciliate taxa from 15 genera were identified; the dominant species was Mesodinium rubrum. The maximum abundance of M. rubrum reached 3.92×104 indiv. dm−3, contributing 95.1% (mean value) to the total ciliate abundance. Diurnal changes in M. rubrum abundance were highly variable, the driving force probably being irradiance and food availability. The results suggest that M. rubrum may form blooms in aquaculture areas when there is a suitable physical regime with enriched nutrients, which is potentially harmful to the fish-farming industry.
