In 2010, there was 140 percent more bluefin tuna being sold in the market then the amount that was reported being caught, according to the Pew Environmental Group.
The Total Allowable Catch quota for 2010 was set at 13,500 tons of bluefin tuna. The Pew Environment Group estimates that 35,000 tons of tuna were actually caught during the year.
Over a 10 year period, up to $4 Billion worth of bluefin tuna was illegally caught around the world.
