Russian fisheries researchers are warning that the latest estimates of the size of the pollock biomass in the country's key harvesting region could lead to a sharp decline in the total allowable catch as early as 2024.

Scientists at Vladivostok-based fishery research center TINRO – the Pacific branch of Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) – reported a decline in the number of pollock in the northern Sea of Okhotsk compared with the previous year.
