Commercial Resources of Saffron Cod, Eleginus gracilis, in Russian Waters of the Far Eastern Seas
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.
期刊介绍:
The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
