Caught and tagged off Ocean City, Maryland and named for an Ohio elementary school, a fast tracking, young mako shark, dubbed “St. Marys”, visits the waters off Halifax today.

The five-and-a-half-foot juvenile male shark is among 35 mako sharks satellite tagged and being tracked by scientists from the Guy Harvey Research Institute (GHRI) at Nova Southeastern University. The institute began tagging mako sharks in 2009 to study their migratory patterns and now undertakes expeditions worldwide to study them. The school’s marine experts have tagged mako sharks as far away as Mexico and New Zealand. In addition to makos, GHRI and Save Our Seas Shark Research Center scientists are also tracking tiger, oceanic white tip and sand tiger sharks, as well as blue and white marlin.


St. Marys, caught and tagged on May 17, 2014, has traveled over 2,100 miles (3,500 km) since it was released off Maryland, according to Dr. Mahmood Shivji, Director of Nova Southeastern University’s GHRI and Save our Seas Research Center. Shivji said his researchers have special interest in understanding mako shark migratory behavior because this information is essential for proper fisheries management of this internationally roving species.

The public can follow St. Marys and other shark movements in near real-time courtesy of an interactive online website set-up by GHRI:

The website is an educational outreach component of the institute’s quest to study shark and billfish long-distance migration patterns, with the ultimate goal being to better understand and protect them, as some species are threatened or endangered.

Established in 1999, the Guy Harvey Research Institute (GHRI) at NSU is collaboration between the renowned marine artist, scientist and explorer, Dr. Guy Harvey, and Nova Southeastern University’s Oceanographic Center. The mission of the GHRI is to provide the scientific information necessary to understand, conserve, and effectively manage the world’s marine fishes and their ecosystems. The GHRI is one of only a handful of private organizations dedicated exclusively to the science-based conservation of marine fish populations and biodiversity. The research, education and outreach activities of the GHRI are supported by the Guy Harvey Ocean Foundation, AFTCO Inc., extramural research grants, philanthropic donations by private businesses and individuals, and NSU.
