“…Lipids: In addition, in the spring, the increase in water temperature is accompanied by an increase in the intensity of metabolic processes, which causes a significant increase in organs and tissues of total lipids, which are the basis for all intracellular membranes [24], [25], [26]. The need for fish for lipids is met by synthesizing them in the body, as well as due to lipids, which are part of the natural and artificial feed base [27], [28], [29].…”

The paper presents the results of scientific research aimed at studying the peculiarities of metabolism in the body of seven species of mature fish in the Kremenchuk reservoir in the pre-spawning period under ecological conditions that differ from existing ones according to the Dnipro Reservoir Rules of Operation. Somewhat increased levels of total protein accumulation were found during this period in the muscles of zander, perch, and gibel carp. More statistically significant differences between the content of total protein in the liver and muscles were found in other fish species, in particular in roach it was 51.2%, in bream – 57.8%, in European flounder, and zope – 40.6%. Slightly elevated total lipids were found in the muscles of these fish. Thus, in the muscles of silver bream, it was 12.07 mg/g of raw weight, and in the muscles of gibel carp – 18.5 mg/g, while in the muscles of all other studied species of fish, this figure was in the range of 6.7 to 8.71 mg/g of raw weight. The glycogen content in the muscles of different objects of the Kremenchuk reservoir in the pre-spawning period was different. Its highest content was found in the gibel carp muscle, which reached 74 mg/g of raw weight. Significantly lower (2.7 times) was the level of glycogen accumulation in zander muscles and 3.2 times – in roach muscles. In the muscles of bream, European perch and silver bream found close, relatively low levels of glycogen, which was in the range of 10 – 13 mg/g of raw mass, and the lowest level of its accumulation was recorded in the muscles of the zope (only 4.9 mg/g). The glycogen content of the liver of all studied fish species significantly exceeded that recorded in their muscles.

“…For aquatic organisms, the accumulation of many lipids provides vital support. It determines the survival of individuals when changing environmental factors in their combination, taking into account the peculiarities of the annual cycle of the organism [18]. Glycogen is a polysaccharide that stores carbohydrates, especially in liver and muscle tissue.…”

Preservation of the nutritional value of fish and the useful qualities of its rich composition is extremely important. The urgent task of the food industry is to develop and create quality food products that meet modern production trends and compete in domestic and foreign markets. This scientific paper describes studies aimed at assessing the specific weight (%) of essential nutrients (glycogen, proteins, and lipids) in particular organs and tissues of different size and mass groups of the hybrid of silver and bighead carp experimental ponds and reservoirs of Ukraine. To achieve the goal in the research process, fish farming, biochemical (study of total protein, lipids, and carbohydrates), and statistical (mathematical processing of research results) research methods were used. In all size and mass groups of the hybrid of silver and bighead carp from ponds and reservoirs in 2017, 2018, and 2019, mostly satisfactory values of general metabolism indicators were found - glycogen, proteins, and lipids in the liver, gills, and muscles of fish. In annual fish of winter ponds, total protein and glycogen content in all organs and tissues was slightly reduced. The organisms of biennial fish from feeding ponds were characterized by fluctuations in the content of glycogen in the liver (it was the highest in fish, 3.28 – 3.33%). Significant fluctuations in the total protein content of muscle, liver, and gills and a slight excess of glycogen in the liver and lipids in the gills of three-year-olds were observed in the reservoirs. The difference found in the availability of essential nutrients in the body of the studied fish indicates a change in the intensity and direction of their metabolic processes. However, their physiological condition at the time of the study was within normal limits.

Purpose. To study morphophysiological parameters of European perch and rudd from the urbanized water bodies of Kyiv in order to use them as indicators of the physiological state of fish. Methodology. The ichthyological study was carried out in different water bodies in Kyiv in May 2021. The material for the study were native species: European perch and rudd. Morpho-physiological parameters were determined separately for males and females. The probability of the obtained results was assessed by a Student’s t-test (Р≤0.05). Findings. Differences in morpho-physiological parameters of European perch and rudd from two water bodies were studied. A high content of oil products in water (0.090 mg/dm3) and bottom sediments (80.5 mg/kg) was found in the Lake Kyrylivske, while their concentration was several times lower in water (0.005 mg/dm3) and bottom sediments (10.5 mg/kg) of the Lake Martyshiv. Differences in the living conditions were manifested in the studied samples of fish. European perch from the Lake Martyshiv had a higher body length and weight by 10.6% and 30%, respectively, compared to the sample from the Lake Kyrylivske. On the other hand, no significant differences in body weight were found for rudd. This indicates the presence of interspecies differences for the studied fish in the living conditions of water bodies under human impact. In addition, differences in morphophysiological parameters have been established in European perch. Condition factor of perch females from the Lake Martyshiv was 16.5% higher than that of females from the Lake Kyrylivske. High liver indices were observed in European perch males from the anthropogenically transformed water body, while rudd males had a liver index lower by 26.3% than that in the Lake Martyshiv. The confirmation of the stressful living conditions in the Lake Kyrylivske during the study period was a significant decrease in gonadal and spleen indices of European perch. Originality. It was established that males and females of European perch and rudd have different physiological reactions to negative living conditions, which were reflected in the indices of internal organs. Practical Value. The obtained results allow assessing the physiological state of most abundant fish communities in urbanized water bodies of Kyiv for further forecasting their abundance and structure. Keywords: European perch (Perca fluviatilis, Linnaeus 1758), rudd (Scardinius erythrophthalmus, Linnaeus 1758), morphophysiological characteristics, organ indices, adaptive reactions, human impact.
