Our results show that the quantity of macroergic compounds (ATP) depends on life´s stage, the age, the sex (male or female) and different environmental factors. Seasonal dynamics of content of ATP especially depends on physiological state of fish (laying down fat, in pick condition, filling on spent).
The dynamics of content of macrorgic substances (ATP) also depends on the degree of the environmental pollution. We conclude that the macroergic compound, such ATP, can be effective molecular bioindicator for determination of negative action of chemicals in aquatic ecosystems. Increase of degree of man-made pollution in water causes the decrease of content of ATP in muscle tissues of north fishes.
One of direction of scientific work is the determination of macroergic substances (ATP) in the muscle tissues of north fishes during process of keeping under low temperatures (-20 ˚С). Our results show that the content of ATP changes during process of keeping (6 months). Our observations show the decrease of quantity of ATP in muscle tissues of north fishes during 6 months of keeping under low temperatures (for example, for the cod the content of ATP decreases from 15mg% to 12 mg% during 6 months of keeping).
The received materials testify the significant role of macroergic compounds in estimation of state of fishes, as components of north aquatic ecosystems.
