Popis: The joint effect of temperature and water mineralization on the content of glycogen, lipids and protein, in gut tissues Rutilus rutilus, Linnaeus, 1758 is considered. As a result of the studies, it has been established that the combined effect of water temperature and mineralization have a greater effect on the balance of energy-intensive compounds than their separate action. This was particularly characteristic of experimental groups that were at an unusual and elevated water temperature of 27–32 °C and a low mineralization of 260 mg/dm 3 . It is shown that for roach the more optimal conditions in the summer are the water temperature of 21–23 °С and its mineralization at 260 mg/dm 3 . As the water temperature rises, there is an imbalance in the utilization or accumulation of reserve substances. It was found that the involvement of protein substrates and glycogen in the energy needs of the body contributed to the growth of a common pool of lipids due to the use of protein metabolism products and hydrocarbon metabolism. It was shown that in the first stages of adaptation of roach to moderate temperatures (25–30 °C) the content of these compounds or remains at the previous level, or increases depending on the mineralization of water. In the second stage, when the water temperature significantly exceeds the climatic levels and reaches 27–32 °C, for successful adaptation to the existing conditions, additional energy consumption, the content of the spare substances and, first of all, glycogen, which is significantly reduced, is required. With reduced water mineralization, these processes require a smaller amount of energy expended. The obtained results can be used for biomonitoring of reservoirs, where an excess of the temperature regime is noted above the climatic norm. Based on this, it will be possible to predict the changes that occur in populations of this species, in particular qualitative and quantitative composition. Also, the results can be used to assess the physiological state in conditions of global climate change and predict the restructuring in the structure of its populations.
