Environmental organization WWF Russia has called for emergency restrictions on halibut fishing and a revision of the total allowable catch (TAC) calculation method, citing a significant drop in halibut numbers in the Far East's fishing regions. The organization argues that the current TAC estimation, based on ship reports, leads to an overestimation and ignores factors like killer whale predation and by-catch of immature fish. Despite these concerns, the Federal Agency for Fishery plans to maintain the current fishing model and has set the 2021 halibut TAC at 13.7 thousand tons, with an expected decrease to 25-30% in 2022.
