[Ecological characteristics of the hemoglobinograms of 3 species of sturgeons].

Studies have been made on fractional composition of hemoglobin in the Russian Acipenser güldenstädti, Siberian A. baeri and Amur A. shrencki sturgeons by polyacrylamide gel disc-electrophoresis. High electrophoretic heterogeneity (6--7 components) of hemoglobin in each of the species was found together with a distinct species specificity of hemoglobinograms. The observed differences in fractional composition of hemoglobin are of an adaptive character which makes it possible to consider the Amur sturgeon as a perspective object for acclimatization in the seas of the Southern region of the USSR with lowered salinity.
