March 14, 2019 — Russian fisheries are getting prepared for expected reductions in total allowable catch (TAC) for Pollock, the biggest species in the national harvest.
Companies are seeking to keep their income stable by investing in processing facilities in an effort to produce more fillet. However, there are doubts that there will be sufficient demand for deeper-processed food.
Generational shift brings new challenges
In Russia, Pollock is fished in the Russian Far East, mainly in the Sea of Okhotsk, the Bering Sea, and the Sea of Japan. In 2018, large stocks of the species were also discovered in the Chukchee Sea – scientists remain eager to find out the reasons for this migration.
Currently, the total biomass of pollock in the Sea of Okhotsk is estimated at 11.6 million metric tons (MT), with six to seven of those tons being fishable. TAC for pollock is traditionally set at a level of about 20 percent of spawning biomass to keep the stock above the target level. TAC in a given year depends on the productivity of recent recruitment, which is affected by a number of various factors, including climate, hydrological, food abundance, etc. While the recruitments of 2011 and 2013 were well above the multi-average level – which resulted in high volumes of harvest – there haven’t been any such productive years since.
