The trend of increasing the average annual temperature of the surface layer of the atmosphere today is given attention with an emphasis on global warming and the consequences of its impact. Warming, which exceeds the global average, is observed in many regions at different times of the year, including, according to estimates, it was found that in the winter-spring period, air temperature in Ukraine increased by 1.1 ‒ 1.7°, and for the southern region ‒ by 1.2° reduction of winter periods, winters became less cold and less snowy
The analysis shows a negative impact of the reduction of winter temperatures on the functional state of fish that overwinter in the ponds of southern Ukraine. Under these conditions, the fish is in the optimal wintering temperatures of adaptive compensatory mechanisms for only one month.
In the range of winter temperatures above the optimum, the planting material of carp fish species actively consumes nutrients at the same time as weight loss and general depletion, which has a negative impact on the body. Modern climatic conditions in the south of Ukraine, which were formed under the influence of global warming, have a significant impact on the existence of aquatic organisms, especially in the period of early embryogenesis. Traditional technology of growing fish planting material in the ponds of the south of Ukraine requires appropriate changes adapted to climate change.
