“…This study has revealed a tendency for more intensive accumulation of heavy metals (Cd, Pb, Zn, Cu, Mn, and Fe) in sabrefish from an area with a high anthropogenic load. A number of studies have also shown that stations located near the industrial complex (Stations 3 and 4) are considered the most unfavorable for aquatic organisms, in terms of heavy metal concentrations in both the water and bottom sediments and according to the results of biotesting in different areas of the reservoir [ 66 , 77 , 87 , 88 ].…”

Nowadays, the problem of inland water pollution is acute. It is caused by vast industrial growth and agricultural intensification. Concentrations of Cd, Pb, Zn, Cu, Mn, Fe, Mg, and Kwere determined in the muscles, liver, and gonads sabrefish from Rybinsk Reservoir areas with different anthropogenic loads. The tissue samples were analyzed by atomic absorption spectrometry. Heavy metals accumulated more intensively in the body of fish from more polluted areas of the reservoir. Among the analyzed elements, the maximum accumulation levels were found for K, Zn, and Fe and the minimum levels were observed for Cd and Pb. The gonads contained the largest concentration of Cd and Mn, the muscles contained the highest concentrations of Mg, and the other elements mainly accumulated in the liver of sabrefish. The THQ and HI values for all elements did not exceed 1, which suggests that there is no potential non-carcinogenic risk to human health. The target values of carcinogenic risk (TR) for cadmium ranged from 8.32 × 10−6 to 1.22 × 10−4 in the muscles. The increased content of cadmium in the gonads of sabrefish not only poses a risk to human health, but also to the reproduction of this species in the Rybinsk Reservoir.

“…A significant role in the metabolic process belongs to water. It participates in many physical-chemical reactions, the normal functioning of cells and tissues requiring its content to be maintained at stable levels, changes in which may be related to unfavourable conditions (Meyer et al, 1956;Martemyanov, 2013Martemyanov, , 2015Payuta et al, 2019b). There are data reporting inverse relation between the content of lipids and share of water in the organs and tissues of many fish (Bano, 1977;Sutton et al, 2000;Payuta & Flerova, 2019).…”

“…Data on the peculiarities of the contents of metabolic products in the organism of fish are the basis for understanding the mechanisms of adap-tations of individuals to changing environmental conditions. Studying the shifts in the accumulation of metabolic products in the tissues of hydrobionts may be an indicator of the conditions of individual species, fish populations, and also the environment they live in (Shearer, 1994;Ahmed & Sheikh, 2017;Payuta et al, 2019b).…”

“…Over recent years, research has been published on the metabolism of hydrobionts depending on the environmental conditions (Ali et al, 2006;Karamushko, 2016;Payuta et al, 2018;Payuta et al, 2019b). Aside from the environmental factors, the influence of sex, age of individuals, and maturity stage of the gonads on the contents of metabolic products in the organism of fish have been noted (Vdovin & Antonenko, 2014;Ganguly et al, 2017;Massresha et al, 2017;Mitra et al, 2017;Payuta et al, 2019a;Payuta & Flerova, 2019).…”

Impact of the factors of the aquatic environment is an inevitable aspect of the life of fish as poikilothermic animals and provokes responses in their organisms. The study focused on determining peculiarities in the composition of the metabolic products in the tissues of different age and sex groups of common bream Abramis brama (L.) depending on the living conditions in the water reservoirs of the Upper Volga. The fish were captured in the fattening period in summer and autumn, measured, weighed, identifying sex, maturity stage of the gonads and age. In the muscles, liver and gonads of bream, we analyzed the contents of water, dry matter, lipids, protein, ash and carbohydrates using the standard techniques. The contents of biochemical components in the organism of bream were to a higher degree determined by the peculiarities of the living conditions rather than sex and age of the individuals. In the muscles and liver of bream living in the conditions of increased water temperature and low concentration of oxygen, the concentrations of protein and ash were lower. In the same tissues of bream from the water bodies with high concentrations of pollutants in the water and benthic deposits, we found increased fat content. The muscles of male bream contained less protein and more carbohydrates than females and juvenile individuals, and the muscles of juveniles had less fat. The environmental factors had greater influence on the content of the metabolic products in the liver of bream than sex, and only females had higher ash content than males. The testes had more fat and less protein than the ovaries. During the transition of the gonads from maturity stage II to III, the contents of dry matter and lipids in them decreased. We determined that the environmental factors have stronger impact on biochemical parameters in the tissues of bream than age, because we found no general age patterns in the dynamics of biochemical components, except the liver, in which the highest content of organic compounds was found in individuals aged 6 to 10 years. Water heated by the Hydro Power Plant positively influenced the young bream, as indicated by higher content of metabolic products in individuals aged 5+ than older groups and bream from the surveyed water bodies. Monitoring of the physiological condition of bream focusing on the contents of metabolic products in the tissues may provide necessary data for successful regulation of bream populations in the water reservoirs of the Upper Volga.
