Investigations were carried out during 1999 and 2000 on Transcarpathian rivers affected by the massive "volley" pollution accidents. Plankton response was manifested in increasing of plankton flow; the response of benthic organisms appeared as increasing of the macroinvertebrate drift. The drift caused by catastrophic pollution events reduced survival chances of hydrobionts and aggravated adverse consequences of pollution impact on the biotic structure in mountain river. Fish mainly try to avoid influence of pollution and, if such possibility occurs, to escape to clean waters of tributaries.

Spatial and temporal changes in microbiological indices were studied in the Uvod reservoir. The numbers of bacterioplankton accounted for 1.6-11 million cells/ml, whereas its biomass was 180-600 mg/L. The numbers of bacteriobenthos were 0.6-12 billion cells/g, whereas its biomass accounted for 0.25-0.80 mg/g of wet silt. The numbers of saprophytic bacteria in water were not more than 1 thousand cells/ml, whereas their numbers in bottom sediments accounted for 100 thousand cells/g. Production ofbacterioplankton was 20-100 mg C/L·day, primary production - 0.34-1.90 mg/L·day, whereas decomposition -0.13-0.80 mg/L·day.

Successions of bacterioplankton registered in Lake Wamiak (Poland) in 1996-1999 were related to changes in its ecosystem conditioned by biomanipulation measures carried out previously. Secondary intensive development of hydrophytes in the littoral zone of the lake was responsible for stabilization of bottom sediments, and also for a decrease in their role in the formation of bacterioplankton. At the same time, the activity of the processes of bacterial decomposition of organic matter remained unchanged.

The species composition and seasonal dynamics of the numbers and biomass of mero- and holoplankton both outside and inside of the oceanarium of Sevastopol Bay were studied during a year. It has been found that meroplankton was represented by 18 species, whereas holoplankton - by 34 species. Seven species of Copepoda were first found in holoplankton of the bay. An artificial protective net occupied by settlements of mussels served as a biological filter.

The structure of Dreissena polymorpha population in the system of the Konin lakes (Poland) used as the cooling system of two thermal power plants was studied in summer 1993-1998. Despite a high diversity of the indices of its numbers, biomass, and dimensional structure the studied population was found to be stable. It is likely that a stable state of D. polymorpha population in the system of the Konin lakes was conditioned by the increase in its biotic diversity related to a wide variety of the environmental conditions, in particular to a great diversity of biotopes.

The interrelationships between body mass and length, height and thickness of the shell, and fecundity of mussels living in Odessa Bay were studied, and coefficients of their reproductive capabilities were calculated. The later experiences an increased influence of hypoxic conditions in the near-bottom water layers.

It is established that fluctuations of the photoregime (frequency oscillations, degrees of illumination and spectral structure of light) accelerates the fish growth at decreasing of the ration. At the same time, the expenditure of food and oxygen per unit of fish body weight is decreased.

A brief historical review of the study of meiobenthos of the Black sea is presented. An analysis of literature data (1880-1998) made it possible to distinguish three stages in the study of meiobenthos of the Black Sea: faunistic, faunistic and chorological, and ecological and faunistic. The part played by Ukrainian scientists in the development of a new direction of marine hydrobiology is great.
