Interannual dynamics of the size composition of the halibut Reinhardtius hippoglossoides in the sea of Okhotsk as a marker of the validity of estimates of its age

Year: 2025

Type: article

Abstract: The results of calculations on the contribution of generations to the size composition of catches of black halibut Reinhardtius hippoglossoides are presented. By calculating the deviations of the proportion of the size class of a particular generation from the average annual share in catches, this contribution can be traced in high-yielding and low-yielding over several years. The interannual dynamics of the generation’s contribution was manifested due to the presence of a dominant age group in the size class. The results obtained allow us to speak about the validity of age estimates from 4 to 11 years old.
