Abstract

Copper and Zinc belongs to essential elements with wide spectrum of physiological and biochemical action in fishes organism. In particular, the role of Zinc in growth, development and reproduction of fishes is established, both as its influence on protein and nucleic acids metabolism and genes activity regulation. Zinc, as well as Copper, is involved in enzyme link of antioxidant system. Besides, Copper takes part in erythropoiesis, energetic metabolism and immune system functioning. Abovementioned elements also influence on desaturases activity. The desaturases are catalyzing transformation of single bond between Carbon atoms in acyl chain into double unsaturated bond. At the same time, Zinc and Copper influence on fatty acids metabolism in fishes body and its tissue and organic specificity remains insufficiently explored. Presented results testified, that at concentration of Zinc and Copper in the water, equated to 1 MPL (maximum permitted level), Zinc accumulates in the gills in greater extend, than Copper. In its turn, at two maximum permitted levels in the water, Copper accumulates in the gills more, than Zinc. Increasing of Zinc and Copper concentration in carp’s gills has led to the increasing of total concentration of anionic forms of fatty acids, those are barely metabolically active. The increasing of anionic fatty acids was caused by saturated, monounsaturated and polyunsaturated fatty acids. Wherein, the ratio of anionic polyunsaturated fatty acids of ω–3 family to anionic polyunsaturated fatty acids of ω–6 family didn’t changed.
