The Indian Ocean Tuna Commission (IOTC) has announced the yellowfin tuna catch limits for 2021 for its member countries, with a total allocation of 177,941 metric tons. The European Union has been allocated the largest quota of 76,258 MT. The limits are calculated based on a 15% reduction of the 2014 or 2015 catch volumes if they exceed 5,000 MT, and also consider the cumulated catch volumes for 2017, 2018, and 2019. The UK has also joined the IOTC, effective from December 2020.
