The study of the hydroecological situation in lakes of the Volyn Polesye suggests that the processes of intensive aging are registered in them. The extraction of sapropel from lakes is one of the ways of their restoration. The chemical composition of sapropel, and also a low content of radionuclides in it, make it possible to use sapropel in agriculture.

The state of macrozoobenthos of the Kanev reservoir was studied on the basis of results of investigations of biodiversity. Water quality was assessed using biotic, saprobic, and ecological and sanitary indices. Water quality assessment in terms of these indices produced somewhat different results. Changes in the structural characteristics of communities and populations of hydrobionts occurring in the littoral zone in response to anthropic load should be taken into account in monitoring water bodies.

The role of benthic Protozoa and microinvertebrates in the process of organic matter decomposition was studied. The total decomposition was determined in terms of the balance of carbonic acid, which made it possible to take into account an anaerobic component, it has been found that free-living Ciliata have a dominant role in the processes of organic matter transformation. Their contribution to the total mineralization of organic matter on the average accounted for about 3%, whereas their contribution to the consumption of the total primary production of phytomicrobenthos was 4-19%. Copepoda and Rotatoria were also of considerable importance in the processes of organic matter transformation. In the open shallow-water zone, the role of Protozoa and microinvertebrates in the process of organic matter mineralization was higher than that registered in the shallow-water zone of the closed type.

The phenomenon of interannual variability of the frequency of occurrence of different phenotypes of albumin, one of the most important functionally specialized blood proteins, is described based on studies of the North Caspian population of Russian sturgeon (Acipenser güldenstädti). Long-term data testify to necessity of critical use of frequency indices of different phenotypes of a given protein obtained during short-term genetic and biochemical studies (one- and two-year observations). A unique biochemical polymorphism of the North Caspian Russian sturgeon has been discovered including 38 phenotypes of albumin.

While studying the regularities of body part development in Pacific ocean perch (longjaw rockfish), systematization by the indexes of plastic characters should be performed in conformity with the segments of ontogeny having different correlative growth and development of external body parts, which could be found in several fish populations.

Peculiarities of the nitrogen compounds transformation in the system for mass cultivation of Moina macropora under the influence of increased food loading and developing crustacean culture are considered. It is stated that heterotrophic bacteria play a determining role in the formation of quality of the cultural medium and food base of zooplankters cultivated. The influence of M. macropora on mediums quality led to decreased numbers of the saprophytic bacteria group, reduction of oxygen deficiency, accelerated organic matter degradation process and increase in NH+4 level.

In the second part of the 1980s, the mussel bank "Tetis-2" was subjected to intensive anthropic silting as a result of which the numbers and biomass of mussels, and also the area of their distribution, essentially decreased. At the thickness of silt of 3 cm, the biocenosis of mussels gave way to the biocenosis of Melinna palmata (Grube) (Polychaeta). The capability of mussels for production and filtration decreased. As a consequence, the process of aging of mussel population was observed.

Results of hydrological and hydrobiological investigations of the Konyk strait after transformation of its riverbed are presented. In the Konyk strait, the quality of water is better than that registered in the Dnieper river. A high productivity of the strait is favorable for the development of the fish fauna.

Macrozoobenthos of the upper reaches of the Kakhovka reservoir was investigated. The state of communities of benthic invertebrates was assessed in terms of six indices of benthos, and also in terms of the combined index of the state of a community.

The influence of some surface active substances on the filtration activity of marine Bivalvia was studied. It has been found that both anionic (sodium dodecylsulphate) and cationic (tetradecyltrimethylammonium bromide) surfactants inhibited the filtration activity of oysters (Crassostrea gigas). Some mixtures containing surface active substances also inhibited the filtration activity of C. gigas and Mytilus galloprovincialis. The obtained data correlate well with the results obtained previously. They suggest that some xenobiotics and pollutants inhibited the filtration activity of other species of marine and freshwater Bivalvia. This experimental approach is useful in evaluating the influence of surface active substances on marine ecosystems.

The effects of copper ions at concentrations of 0.5 μ;g Cu2+ /L, 2 μ;g Cu2+ /L, 5 μ;g Cu2+ /L, and 10 μ;g Cu2+ /L on the processes of glycolysis and Krebs cycle in the liver, gills and muscles of carp were studied. At below-threshold concentrations of Cu2+ ions (0.5 μ;g /L) in the aquatic environment, the energy supply of adaptation processes in carp is performed mainly by the aerobic pathway. At their increased contents in water up to 2 μ;g Cu2+ /L, 5 μ;g Cu2+ /L, and 10 μ;g Cu2+ /L, aerobic processes are inhibited in fish tissues, while glycolytic processes are activated.

Twenty-nine zooplankton samples were collected in the Uglich, Rybinsk, and Gorki reservoirs. Pathological alterations of the brood pouch structure disturbing its function were registered in 25 samples of Leptodora kindti. Numbers of individuals affected varied in the samples from 2.8% to 23%.

It was shown that the optimal maintenance conditions and group crossings of mussels resulted in the highest growth and survival rates as compared to other types of crossing and autogamy. The ways of obtaining the pure lines are described. In cases of autogamy and closely-related crossings, the inbreeding depression is revealed at the periods of transition into the next stage of larval development.
