New satellite tags track the movements of Atlantic Bluefin Tuna.

A new satellite tagging technology has proven that it can help resolve the mysteries of tuna migration at a time whenmanagement strategies for these remarkable and commercially valuable fish are in dispute and their breeding population isin sharp decline.

The microprocessor tags, deployed in 1996 and 1997 by scientists from Stanford University, the Monterey BayAquarium and the National Marine Fisheries Service, revealed that tunas tagged off Cape Hatteras, N.C., were able tomove as far as 1,670 nautical miles in 90 days -- and that some fish crossed the line separating eastern and westernmanagement zones for the bluefin fishery.
