Otolith microstructure of the Russian sturgeon, Acipenser gueldenstadti was examined in adult samples collected in the Caspian Sea. The microstructure of the otolith was the same among specimens. The anterior side of the sagitta grew in two directions elongating both the long and short arms, and the long arm sections exhibited 14-21 distinct translucent and opaque zones. Otolith increments in this species can be used for age determination.
