Where is tuna caught?
Tuna is fished in oceanic waters throughout the globe, except the polar seas. More than 70 countries worldwide fish tuna, but the majority of the tuna supply comes from the Pacific Ocean.
As of 2009, about 65% of the global tuna catch comes from the Pacific Ocean, 26% percent from the Indian Ocean, and the remaining 9 % from the Atlantic Ocean and the Mediterranean Sea. Tuna inhabit the upper and middle layers of ocean water to a maximum depth of approximately 1,600 feet (500 meters), depending on size and species.
