Scientists use tags, or marks implanted on fish, to learn about the fish behavior and to estimate important population parameters such as abundance, mortality and movement. The size or weight of the fish, including the type of measurement Any other additional information you can give us could be very useful. In addition, we must receive the tag and written notification of the tag return.

View a List of Addresses where tag returns can be reported. For several years, three draws have been held, one each for billfish, temperate tunas and tropical tunas. Tags recovered prior to 1 January 1999 and not submitted for entry in previous lotteries may also be included. The winning tag numbers will be announced as soon as the draws have been held, and the corresponding prizes will be sent to the winners. In March 1996, a research team headed by Stanford Universities Hopkins Marine Station, the National Marine Fisheries Service and Monterey Bay Aquarium's Tuna Research and Conservation Center successfully tagged ten giant Atlantic bluefin tuna with the first archival tags.
