The North Carolina Sea Grant College Program 



is a federal/state program that promotes 

 stewardship of our coastal and marine resources 



through research, extension and education. 

 It joined the National Sea Grant College Network 

 in 1970 as an institutional program. Six years later, 



it was designated a Sea Grant College. 

 Today, North Carolina Sea Grant supports research 

 projects, a 15-member extension program and a 

 communications staff. Ron Hodson is director. 

 The program is funded by the U.S. Department 

 of Commerce's National Oceanic and Amiospheric 

 Administration and the state through the 

 University of North Carolina. 

 Coastwatch (ISSN 1068-784X)

Duke University's Marine Laboratory in Beaufort supports tuna-tagging research 

 led by Barbara Block, center, of Skin ford University. 



Tagging Tuna at Duke Marine Lab 



searchers at Duke University Marine 

 Lab hope to establish a permanent large 

 ocean fish-tagging program in the near future. 



Now, Duke is the East Coast partner 

 forTag-a-Giant, a tuna research program 

 headquartered at Stanford University. A team 

 of Stanford scientists, led by Barbara Block, 

 visit Duke each year to work with local charter 

 boat owners to tag bluefin tuna. 



The tags measure body temperature, 

 water temperature, water depth and light 

 sensitivity and enable scientists to track a 

 tuna and know where and when it dives and 

 eats. One tuna tagged in North Carolina was 



tracked over a two-year migration that spanned 

 ocean waters from Iceland to the Canary 

 Islands. 



Potentially, a Duke-led Tag-a-Giant 

 program could figure in the lab's Pivers Island 

 expansion project underway. Lab director Mike 

 Orbach estimates that it would take $1 million 

 a year to run the program full time. 



Such tagging programs provide valuable 

 information for National Marine Fisheries Ser- 

 vices and regional fishery management councils 

 responsible for developing and enforcing fishery 

 management plans for highly migratory species, 

 such as tuna. — P.S.

"Travel with JasonTalley on board a North Carolina ferry destined for your favorite beach. And, 

 Ann Green will explore new federal regulations for recreational anglers seeking highly migratory 

 species, such as tuna and marlin.
