Abstract
The data on catch dynamics and structure of saffron cod fishery off the southeast coast of Sakhalin Island from 1946 to 2023 are presented. The catch of saffron cod during these years ranged from 0.01 to 13.83 thous. t, and averaged 4.91 thous. t. It is shown that the main fishery is concentrated in Terpeniya Bay and was carried out using twin trawls on spawning aggregations in January. In the post spawning and feeding aggregations, fishing was conducted with saffron cod traps (fyke nets) in the area of the Capes Tikhii and Senyavina in February–March. Amateur fishermen predominantly fished for saffron cod in the same area. Over the long period of exploitation the structure of catches has undergone noticeable changes: before 1970, fishing was carried out exclusively with the use of tyke nets, since the early 1970s the basis of catches is provided by trawl fishing, since the early 2010s, along with industrial development, the volume of catches by recreational fishermen has been increasing. In the last decade, the ratio between catches of commercial fleet, fyke nets and recreational fishery was 89%, 6% and 5%, respectively.
