[Population analysis of electrophoretic variation in blood serum albumins of European (Acipencer ruthensis L.) and Siberian (A. ruthensis marsiglii Brandt) sterlet].
We studied blood serum albumins in European (Acipencer ruthensis L.) and Siberian (A. ruthensis marsiglii Brandt) sterlet using disk electrophoresis in polyacrylamide gel. The albumins were shown to be controlled by three codominant alleles of a single locus (ALB*a, b, c). In European sterlet, all three theoretically possible genotypes were described, one of which (ALB*c/c) occurred extremely rarely (one individual). Siberian sterlet was found to be monomorphic for albumins: all fish examined had the ALB*a/a genotype. There was no correlation between albumin patterns and fish fatness. In a number of samples from the Volga River basin, spatial and temporal differentiation was found and analyzed. The results suggest that construction of hydroelectric plants may provoke massive and prolonged starlet migrations.
