Abstract: The qualitative composition of the Caspian Sea sturgeon has been studied on the basis of multiyear factual material. The relationship between the length, weight and age, marked a slowdown of growth the sturgeon. At present, the size of the population of Russian sturgeon and other major sturgeon species as beluga and stellate sturgeon have fallen sharply in the last 10-15 years (2000-2016), almost the recruitment absent, both, from the natural and of aquaculture. The findings suggest that the anthropogenic factor, over the past 40 years, has a negative impact on the biological productivity of fishery water bodies (Caspian Sea and adjacent rivers) and have an impact on fishes, their biological and physiological state. Evaluation of morphophysiological transformations in sturgeons based on the use of a variety of morphophysiological and biochemical parameters gives us grounds to speak about a certain deterioration of the physiological conditions of these fishes over time, in the sea and river periods of their life.
