A paper published in Ocean and Coastal Management titled “Multiple lines of evidence highlight the dire straits of yellowfin tuna in the Indian Ocean” reveals that yellowfin tuna populations are at risk of disappearing from dishes such as sashimi and poke bowls due to over-exploitation. The study shows that the global biomass of yellowfin tuna has decreased by an average of 54% since industrial exploitation began in 1950. In the Indian Ocean alone, there has been a 70% decline in the past 70 years. The researchers propose stricter management measures, including a 30% reduction in catch levels, to prevent further decline.
