Abstract
The sympathoadrenal system plays an essential role in forming the body's response to the action of stimuli of various natures and intensities. The content of deposited catecholamines in peripheral blood erythrocytes is one of the most accessible parameters for an adequate description of the functional activity of the sympathoadrenal system in humans and rats. The aim of the work is to assess the accumulation of catecholamines in erythrocytes of sea ruffs Scorpaena porcus L. at various pollution levels in the bays of Sevastopol (we used a cytochemical method for fish). The phenomenon of accumulation of catecholamines in erythrocytes of the peripheral blood of fish is revealed. The concentration of erythrocytes with deposited catecholamines was higher in fish from polluted bays. The level of deposited catecholamines in fish erythrocytes indirectly reflects changes in the activity of the sympathoadrenal system and can serve as a subtle indicator of the physiological state of poikilotherms under stress of various natures.
