Abstract
Fifty percent of Pacific cod Gadus macrocephalus males reach sexual maturity in waters of Primorye at the age of 2+, while the age of female sexual maturation is 4+; 100% sexual maturation occurs at the age of 6+ and 7+, respectively. According to the long-term average data, the general number of males is 1.2 times larger than that of females in the population; among mature individuals, the number males is 1.7 times larger than females, which is required for successful spawning.
