Overfishing continues despite repeated warnings. In 2007, researchers from the International Commission for the Conservation of Atlantic Tunas (ICCAT)—the regulators of Northern bluefin fishing—recommended a global quota of 15,000 tonnes (15,000 long tons; 17,000 short tons). ICCAT then chose twice that number, later dropping it to 22,500 tonnes (22,100 long tons; 24,800 short tons). Their scientists now say that 7,500 tonnes (7,400 long tons; 8,300 short tons) is the sustainable limit. In November, 2009 ICCAT set the 2010 quota at 13,500 tonnes (13,300 long tons; 14,900 short tons) and said that if stocks were not rebuilt by 2022 it would consider closing some areas.[3] The fishing industry continues to harvest 60,000 tonnes (59,000 long tons; 66,000 short tons) tons yearly.
