From 1920 he taught at Moscow State University. In 1930 he was appointed head of the subdepartment of hydrobiology at Moscow State University.

Skadovskii’s principal works dealt with the ecology and physiology of aquatic organisms. He developed methods for stimulating the sexual maturation of fish and for hatching sturgeons in reservoirs with slow outflow. He studied metabolic processes in aquatic animals and plants.
