Abstract
The Pacific perch is the most numerous species of the genus Sebastes. The extensive range of the beaked perch and the peculiarities of the distribution of high-density concentrations in limited areas make it very difficult to assess its stock, and intensive fishing leads to the undermining of stocks for a long period. The current state of the stocks of beaked perch in the EEZ of Russia is considered and retrospective data on the fishing of the species in the main areas of world fishing are presented. Based on the expedition materials collected in 2021-2022 in the Bering Sea, the age was determined and the growth rate of the beaked perch was considered. A brief overview of the size composition of the perch herd of the East Kamchatka and North Kuril fishing zones is also given based on materials collected in February – April 2024. The age determination technique is described in detail and, based on the age definitions of fish of different lengths, a size and age key is calculated for practical use.
