Abstract
Gonad size and weight dynamics and gonad-somatic index in the course of maturation have been analyzed, size structure and condition of oocytes of Pacific saffron cod at different stages of ovary matura- tion has been clarified. Reproductive cycle has been demonstrated, and scale of gonad maturation stages has provided.
