Essential elements in the organs and tissues of fish depending on the freshwater toxicity and physiological state

Abstract

The distribution of essential elements (Са, Mg, Na, K, Zn, Cu, Mn, Co) in organs and tissues in basins with different water toxicity is considered by the example of bream Abramis brama L. The models of redistribution of essential elements in the liver and kidney of the fish are developed depending on the physiological state, which is estimated by the concentration of hemoglobin in blood, total disease, and body mass index. It is shown that essential elements can serve as markers of intensity and direction of metabolic processes in the fish organism.
