The distribution of periphyton algae on the substrates of various types was investigated in the transboundary Stviga River. It has been found that phytomicroperiphyton was formed mainly by Bacillariophyta and Chlorophyta.
The classes Bacillariophyceae, Chlorophyceae, Euglenophyceae, Zygnematophyceae, and Hormogoniophyceae contributed significantly to the total number of species, numbers, and biomass. The largest number of species
and the highest numbers and biomass of periphyton algae were observed on stones, whereas their highest information diversity – in the fouling of Hydrocharis morsus-ranae.

On the whole, 108 species (121 infraspecific taxa, including those containing nomenclatural types of species) of plankton algae of 7 divisions were found in the cascade of ponds. Euglenophyta, Chlorophyta, and Bacillariophyta were represented by the largest number of species. Phytoplankton of the studied water bodies was not diverse in its species composition. It was characterized by a predominance of Euglenophyta and Chlorophyta. In terms of the saprobiological characteristics of indicator species, the studied water bodies belong to the class "slightly contaminated". They were characterized by a predominance of
plankton and plankton and benthos, eurythermal, and indifferent in relation to water salinity and pH algal species. Valid correlation was established between
the concentration of ammonium and phytoplankton biomass, and also between permanganate oxidizability and phytoplankton numbers.

Taxonomic composition and quantitative characteristics of pelagic mesozooplankton of Lake Baikal in spring over the years 2009–2014 was studied on the basis of materials of regular surveys. Zooplankton biomass and numbers varied within the limits documented previously (1961–1993). Species
composition was typical for the season. In 2014 in the Central and Southern sections of the lake number of rotifers was extremely high.

The article presents data about the new finding of the sea zander Sander marinus in the Dnieper-Bug estuary. Morphological analysis of characters of three zander species showed that à specimen caught on 21 September 2016 in the
Dnieper-Bug estuary belongs to Sander marinus (Cuvier, 1828). Meristic and plastic features also were analyzed. Among them the most important for differentiation of sympatric species of zanders were selected. Based on the
results of data analysis we can conclude that the sea zander is actually not completely extinñt, but only neglected in the analysis of commercial catches as the Red Book species, which is strictly forbidden for fishing.

Forming and development of algoflora of the Akdarya reservoir depends on state of phytoplankton of the Zarafshan River. Algoflora of the reservoir comprises 71 intra-species taxa (63 species, 16 varieties and 1 form) of 4 phyla,
10 orders, 14 families and 24 genera. Maximal species number belong to Bacillariophyta (56 IST), Cyanophyta comprise 9 IST (8 species and 1 form), Xanthophyta and Chlorophyta – respectively 4 and 2 species. Classes Hormogoniophyceae, Pennatophyceae and Heterotrychophyceae were polymorphic, they comprised 65 IST (91% of total number), 6 polymorphic families (62 IST, 88%) and 7 polymorphic genera (53 IST, 75%).

A new approach to establishment of the ecological potential of heavily modified and artificial water bodies, technoecosystems is proposed. Similar to principles of the EU Water Framework Directive, it is based on the comparative methodology. As a benchmark for comparison (reference), it is proposed to
develop "technically and environmentally acceptable characteristics of the state" of a waterbody or a techno-ecosystem.

The influence of glucose and glutamic acid on the biomass and chlorophyll a content in representatives of Bacillariophyta (Mayamaea atomus), Chlorophyta
(Desmodesmus brasiliensis), Streptophyta (Cosmarium polygonum var. acutius), and Euglenophyta (Euglena gracilis) was investigated. It has been found that all studied species are characterized by mixotrophic type of nutrition. It has been shown that the influence of glucose and glutamic acid on growth characteristics and chlorophyll a content in representatives of various algal divisions is species-specific.

The fatty acid composition of lipids in the liver and heart of sterlet under hypoxia and hypercapnia (artificial hypobiosis) and exit from this state has been
investigated. The decrease of the saturated and increase of the unsaturated fatty acids content was noted. The features of these changes in sterlet liver and heart were revealed. The redistribution of the polyunsaturated fatty acid composition in the sterlet tissues results in changes of ω3/ω6 ratio. This mechanism may be involved into the process of cellular adaptation to artificial hibernation in fishes.

Results of long-term investigations of the content of zinc and forms of its occurrence in the reservoirs of the Dnieper cascade and in some rivers and small water bodies located within the territory of Kiev have been generalized in the
paper. In recent years, its concentration in the studied water bodies varied over a wide range – from 10.2 to 158.6 μ;g/L. Data on the content of zinc in rivers, lakes,
and reservoirs of other regions of the world are also given for comparison. It has been found that in the polluted surface waters the concentration of Zn(II) attains
hundreds and even thousands μ;g/L. Zinc migrates mainly in the dissolved state as a result of its binding into the complexes with natural organic ligands. Mass
contribution of Zn(II) in the composition of suspended matter on the average accounts for 8.9–49.4% Zntotal. The contribution of zinc labile fraction (potentially bioavailable) is not more than 12.0–30.0% Zndis. Anionic complexes prevail among organic compounds of Zn(II). Their contribution on the average accounts for 44.8–54.8% Zndis. Their contribution increases with increasing the concentration of humic substances. Carbohydrates are of considerable importance in the process of complexation in summer and autumn. Thus, during these seasons the content of Zn(II) neutral complexes increases. Mainly organic compounds with the molecular mass ≤ 5.0 kDa are involved in the process of complexation with Zn2+ ions.
