The performed investigations have shown that in the Kiev Reservoir the species richness and abundance of epiphytic algae occurring on higher aquatic plants of various ecological groups essentially differed. On submerged plants,
the number of epiphytic algae species was 1.3 and 2.0 times higher than that on half-submerged and plants with floating leaves, respectively. On submerged plants, the average numbers of phytoepiphyton were one order of magnitude
higher than those on half-submerged and plants with floating leaves. In this case, on submerged plants its average biomass was one order of magnitude higher than
that on plants with floating leaves and two orders of magnitude higher than that on half-submerged plants. The taxonomic structure and species composition of
phytoepiphyton were closely similar on half-submerged and submerged plants and somewhat differed on plants with floating leaves. It is underlined that the peculiarities of the distribution of epiphytic algae on higher aquatic plants of various ecological groups should be taken into account in assessing the ecological state of water bodies by the method of bioindication.

Mollusk Ferrissia fragilis (Tryon) was found for the first time in the Dnieper river basin – in benthos samples, taken from the Kyiv reservoir in August 2013 and in July 2014. On the basis of our own survey and literature data we suggest that Ferrissia fragilis did not invade Eurasian fresh waters at the end of the 20th –
beginning of the 21st century, but had inhabited water-bodies of this region long before. It is suggested to give F. fragilis the widespread species status.

The inter-annual dynamics of zooplankton in the open section of the Maloye More Strait (Baikal) from late XX to early XXI centuries is presented as continuation of the long-term investigations. Composition and quantitative
parameters of the spring plankton and its main component Epischura baicalensis Sars, 1900 were investigated. The data on E. baicalensis biomass in 1997–2014 were compared with those of the long-term observations for 1964–1974. Recently increase of zooplankton biomass was noted owing to domination of copepod stages and mature specimens of E. baicalensis due to earlier reproduction of its spring generation. It was supposed that stated changes of the Epischura's population were caused by changes of ice-thermal and water regime of Baikal.

numbers and biomass of fishes
The method of determination the potential abundance and biomass of benthos-eating fishes in inland waters includes analysis of feeding base of a water body and size and age structure of fish populations. First of all, total
bioproduction of all forage macrozoobenthos, which is used by fishes in standard, plastic and generative metabolism, over the vegetation period is calculated. Further, considering biological characteristics of the studied species and fluctuations of environmental factors, total number of individuals of all species in a water body is calculated. Finally, on the basis of the relative
abundances and average mass of each species in catches, total biomass of fishes and separate species in a water body is determined. This method accounts peculiarities of biology of the considered fishes and thus provides higher
accuracy as compared with standard fishery methods which are based only on calculation of general forage coefficient.

New data on biology and morphology of the isolated population of the Baikal grayling Thymallus baicalensis from the mountainous Gitara Lake are given. The features were determined that distinguish it from other populations of the species inhabiting the Lake Baikal and mountainous water bodies of the Baikal-Sayan region, which is the result of adaptation to extreme conditions of the ultraoligotrophic lake and isolation from other populations of the species.

The taxonomic composition of the communities of cultivated heterotrophic bacteria from the areas of water of the Sea of Japan (the Primorskiy Kray, Russian Federation) differing in the intensity of anthropogenic load has been
investigated. It has been shown that in the bacterial communities occurring in the bays constantly subjected to contamination by industrial and household sewage
the contribution of facultative pathogenic microorganisms is rather high, whereas the groups of microorganisms typical to clean sections are absent. The interpretation of results in terms of amylolytic and proteolytic activity of bacteria in studies of ecological and trophic structure of microbial communities proved to be inefficient.

Results of long-term investigations of the co-existing forms of chromium in water bodies of various types (rivers, reservoirs, lakes, and ponds) are given in the paper. In the studied water bodies, the total concentration of chromium varies over a wide range accounting for 1.7–71.4 μ;g/L. The lower reservoirs of the Dnieper cascade located in the industrial zone proved to be most contaminated
by its compounds. However, as compared to the 1980–1990s their concentration essentially decreased, which was conditioned by a decrease in the intensity of
industrial production. A rather high content of chromium is observed in some lake systems of Kiev, which is conditioned by a high intensity of anthropogenic load. In the studied water bodies, with the exception of the rivers of the Pripyat River basin and the Ukrainian section of the Danube River, chromium migrates mainly in the dissolved state, where it is represented mainly by the compounds of
Cr(III).The concentration of Cr(VI) is almost always lower than the limit of its detection by the photometric method. The absence of Cr(VI) is determined by its reduction under conditions of natural surface waters to non-toxic Cr(III). The complex compounds of chromium with organic substances of various chemical natures prevail in the composition of the dissolved form of chromium. Humic substances and carbohydrates are of considerable importance in complexation. The major portion of Cr(III) was found in the composition of complex compounds with the molecular mass of not more than 5.0 kDa.

Paper deals with facts of invasion and mass development of planktonic Cyanobacteria of tropical and subtropical origin (Cylindrospermopsis raciborskii, Sphaerospermum aphanizomenoides, Cuspidothrix ussatschevii) in
technoecosystems of thermal and nuclear power plants of Ukraine. C. raciborskii has been registered in the cooling ponds of the Zuevska TPP and Zaporizhzhya
NPP and also in the littoral part of the cooling pond and fish ponds of the Khmelnitskiy NPP technoecosystem, where it caused "hyperbloom". Sph. aphanizomenoides and C. ussatschevii were found in the cooling pond of the Zuevskaya TPP. Quantitative parameters of the first were insignificant, whereas biomass of the second at maximum caused intensive "bloom".
