Gonadal Stage and Sex Steroid Correlations in Siberian Sturgeon, Acipenser baeri , Habituated to a Semitropical Environment
Stages of gonadal development, in association with plasma concentrations of the sex steroids 17β‐estradiol (E2), progesterone (P4), testosterone (T), and 11‐ketotestosterone (11‐KT), were investigated for a single time point during a natural breeding season in 7‐yr‐old Siberian sturgeon, Acipenser b...
