[Heterogeneity and polymorphism of functionally specialized blood proteins of migratory fish based on the example of the North Caspian population of Russian sturgeons during the sea and river periods of life. 2. Hemoglobins].
We carried out comparative studies of the heterogeneity and polymorphism of the most important functionally specialized blood proteins, hemoglobins. The fractional composition of hemoglobin proved to be identical during the sea and river periods of life for all main parameters (number of components, relative mobility, and protein content of each component). This puts the Russian sturgeon in a special position with reference to migratory teleostean fish, specifically salmonids, in which the specific weight of the protein of "slow" and "fast" hemoglobins undergoes changes upon change of the habitat.
