[3] The headquarters of the IATTC are located in La Jolla, San Diego, California, United States.

The IATTC, through the Achotines Laboratory is a major contributor of research in the early life history of tropical tunas.

It is one of the few research facilities in the world designed specifically for studies of the early life history of tropical tunas.

The Achotines Laboratory provides a unique setting for studying the reproductive behavior and early life stages of tropical tunas.

While tunas are the main focus at the Laboratory, there are ample facilities to support research in other areas of marine and terrestrial science.
