Abstract

The current status of the stocks, the dynamics of commercial fisheries, and the distribution of the saffron cod Eleginus gracilis in the fishery areas of the Far East are analyzed. In the Far Eastern basin, saffron cod makes the greatest contribution to the total catch of aquatic biological resources in the Karaginsky subzone (8.1%) and off western Kamchatka (3.6%). The total saffron cod catch from the Far Eastern seas in 2003–2022 ranged within 16 700–50 600 tons, with an average of 33 900 t. According to the data of bottom trawl surveys conducted in 2016–2023, the largest saffron cod aggregations are traditionally observed in the shelf waters off western Kamchatka, in the southwestern and northwestern Bering Sea, where the catch per unit effort reaches 4500 kg per trawling hour. Off western Kamchatka, the biomass of this species was estimated at 197 400 t; in the Karaginsky subzone, 100 400 t; in the West Bering Sea zone, 32 800 t; in the East Sakhalin and Petropavlovsk-Commander subzones, the values were similar, 17 100 and 17 200 t, respectively; and in the North Okhotsk Sea area, 8700 t. Almost all the exploited stocks in recent years have been above their average long-term annual level or fluctuated within its range. In general, the status of the saffron cod stocks in the fishery subzones at the present time can be considered satisfactory.
