Fishing and stock assessment of the Siberian Cisco Coregonus sardinella (Coregonidae) in the Gydan basin

This study provides information on the long-term catch and fishing structure of the Sardine cisco Coregonus sardinella in the Gydan basin. A brief biological characteristic of the species is presented. Using the population model CMSY estimates of the size of the Siberian grouse stock and guidelines for managing its fishery were obtained. The model values of biomass turned out to be close to the results of studies in the 1980s.Based on the data obtained, a conclusion is made about the high number of siberian cisco in the basin under consideration. Various forecast scenarios for further management of the fishery are proposed.
