According to new data from the Indian Ocean Tuna Commission (IOTC), overfishing of yellowfin tuna in that region continues, despite the fact that the species has been classified as overfished since 2015, and has been the subject of a rebuilding plan since 2016. Although last year’s catch of yellowfin was down from 2018, it was still more than 100,000 metric tons, or approximately 25% higher than what scientists say is needed to have even a 50% chance of rebuilding the population by 2027.
