|Tuna and tuna-like species are very important economically and a significant source of food. They include approximately forty species occurring in the Atlantic, Indian and Pacific Oceans and in the Mediterranean Sea. Their global production has tended to increase continuously from less than 0.6 million tonnes in 1950 to almost 6 million tonnes today.|
The so-called principal market tuna species are most important among the tuna and tuna-like species from the catch weight and economical view points. They are landed in numerous locations around the world, traded on the nearly global scale and also processed and consumed in many locations worldwide. In 2003, their catch was approximately four million tonnes, which represents about 65% of the total catch of all tuna and tuna-like species. Most catches of the principal market tuna species are taken from the Pacific (64.2% of the total catch of principal market tuna species in 2003), with the Indian contributing much more (25% in 2003) than the Atlantic and the Mediterranean Sea (10.8% in 2003).

Atlas on tunas and billfishes
An interactive Atlas presenting the global distribution of 1950 to 2003 catches, at 5° latitude by 5° longitude resolution, of those tuna and tuna-like species for which this distribution is generally well known on the global scale. These species consist of the so-called principal market tunas and some billfishes.
