Geographical Distribution
Yellowfin tunas are found worldwide in tropical and subtropical waters, from latitudes of approximately 40 ?? N to 35 ?? S. They are absent in the Mediterranean Sea. The yellowfin tuna is a highly migratory fish. In the Pacific Ocean, however, there is little evidence for long-range north-south or east-west migration. This suggests relatively little genetic exchange between the eastern, central, and western Pacific Ocean and perhaps the development of subspecies.
Habitat
The yellowfin tuna is an epipelagic, oceanic fish, living above and below the thermocline, at temperatures of 65 to 88 ?? F (18-31 ?? C). It is generally found in the upper 330 feet (100 m) of the water column.
