SPECIFIC FEATURES OF METAL ACCUMULATION IN THE RUSSIAN (ACIPENSER GUELDENSTAEDTII, BRANDT, 1833) AND PERSIAN (ACIPENSER PERSICUS, BORODIN, 1897) STURGEON OF THE CASPIAN SEA

Abstract

In the course of the research, the biological features of the accumulation of microelements by the organs and tissues of the Persian sturgeon in comparison with the Russian, as well as the regularities of the age accumulation of sturgeon were revealed. Studies of the elemental composition of organs and tissues of the Persian (Acipenser persicus, Borodin, 1897) and Russian (Acipenser gueldenstaedtii, Brandt, 1833) sturgeon revealed a number of specific features associated with different rates of metabolic processes in fish: the level of iron, copper, manganese, zinc, and mercury in the Persian sturgeon (Acipenser persicus) in almost all organs and tissues, it was recorded higher than in the Russian, at the same time, the content of cadmium and cobalt indicates its greater accumulation in the organs and tissues of the Russian sturgeon (Acipenser gueldenstaedtii).
