Consortia of macrozoobenthos with determinant center Dreissena + Unionidae have been studied. The consortia is formed in the littoral zone of the water-reservoir owing to symbiosis (commensalism) zebra mussels and clams. The flow of energy through this community and its parts were calculated.

The main stages of radioecology development, including radioecology of natural bodies of water, are analyzed. Levels of radioactive contamination of natural waters because of nuclear weapons testing in the 1945–1980s have been estimated. The main priorities of the post-Chernobyl stage became the investigations of ecological consequences of nuclear accidents and elaboration of scientific principles of ecological safety under conditions of increasing chemical contamination of the biosphere. The priorities for research of natural waters at the end of the second millennium – the beginning of the third millennium are determined.

An analytical review is presented on bioassays on Daphnia magna and other cladocerans (Crustacea: Cladocera) used in biotesting of water environment toxicity. The survey as a whole, criticism and recommendations contained therein are founded on the many years data of domestic and foreign literature as well as the author’s own experience. Amendments to biotesting methods are proposed.

A dispensability of bottom deposits is considered as an essential factor determining the life conditions of benthic organisms, freshwater nematodes in particular. A volumetric mass of matrix solid material ("skeleton") of bottom sediments as a rather indicative parameter of a natural substrate for nematodes is emphasized.

The article, the issues of the importance of application of physiological, biochemical and other instrumental methods in enhancing the reliability of diagnostics in ichthyopathology and assessing the environmental influence on fish are discussed. The effectiveness of some of these methods is exemplified by the results of experiments conducted by the authors. Further search of methods suitable for field conditions is highly desirable.

The kinetics of spontaneous transformations in crude oil (forming fractions and film, sorption, evaporation) in the aquatic medium was under laboratory studies. There have been stated the degrees of toxicity of crude oil, diesel fuel, and gasoline (petrol) to laboratory culture of D. magna. Bioassays with daphnia may be recommended to reveal the presence of petroleum and products of its processing in the water.

The study presented concerns a troublesome problem of the fish farming in warm waters. The body mass and length, and also the common protein levels in the blood serum, internal organs and muscles of carps affected by parasitic protozoans, monogeneans and cestodes were under study. The infestation by a single representative of these taxa was accompanied by only insignificant shifts in indices studied whereas the invasion scope turned out to be a more essential factor.

The seasonal dynamics of biochemical performances of the matter sedimented in the long-term traps situated at a depth of 1.5 m in the inshore area of the Black Sea had been under study. It is concluded that the variations of the total organic matter, carbohydrates, common protein and photosynthetic activity within a trap contents are interrelated, and a mass therein is a biological system that possesses the balancing mechanisms.

Peculiarities of macrophytes overgrowth and the role of various phytocenoses (plant communities) in the distribution and migration of radionuclides in the Kanev reservoir were analyzed. It was determined that the Nuphar lutea – Trapa natans – Ceratophyllum demersum landscape and vegetation complex and the communities of air-aquatic plants were most effective in processes of self-purification of ecosystems from radioactive contamination.

Results of acute tests demonstrated that colloid sulfur is practically non-toxic for crustaceans Daphnia magna, Moina macrocopa, and Ceriodaphnia affinis. In experiments with sulfur at the temperature 22°C, a significant decrease in oxygen content was observed. In chronic experiments with 250 and 500 mg/L of sulfur concentrations, the reduction of daphnia survival time and fertility was detected in comparison to the control by 55% and 80%, respectively. At 10–100 mg/L these indices were on the control level.

Ions of Hg2+, Cd2+, Cu2+ and Zn2+ had a stimulative effect and increased the metallothionein content in mitochondria and cytosol of mature fish eggs. Binding metals by carbothiolic ligands, dimercaptol protects fish females from adverse effects of heavy metals on metabolic processes in somatic and germ cells of fishes.

The dynamics of development of accompanying bacteria in cultural media of Cyanoprocaryota and Chlorophyta are conditioned by the extent of physiological activity of algae. The content and composition of dissolved organic matter is changing at different stages of culture growth. Non-volatile organic substances prevail during the lag phase, and also at the end of the exponential phase, whereas volatile organic substances dominate at the beginning of the exponential phase and during the period of intensive development of algae. The total numbers and biomass of accompanying bacteria are in direct agreement with the concentration of dissolved organic matter and in inverse dependence with the content of its volatile components. Depending on the stage of culture growth, the contribution of bacterial biomass to the total biomass of Microcystis aeruginosa was 3.32–12.26%, whereas its contribution to the total biomass of Scenedesmus acutus accounted for 0.30–5.74%. The maximum value of this index was registered during the lag and stationary phases of culture growth, whereas its minimum value was observed during the exponential phase of culture growth.
