Abstract
Indicators that reflect metabolic processes of living organisms in the water of the middle course of the Ob River were measured in different seasons of 2016 and 2017. In the winter period, the processes of catabolism predominate. They intensify in mid-February. At this time a sharp decrease in dissolved oxygen (O2) in the water is observed, which results in fish kills. The most intense catabolic processes occur in March, before the river ice breakup. In summertime there is no difference between the day and night periods. It is probable that the internal heterogeneity of water flows has a more significant effect on dynamic indices than the processes of photosynthesis.
