The Guy Harvey Research Institute (GHRI) at Nova Southeastern University (NSU) is a collaboration between renowned marine artist, scientist and explorer, Dr. Guy Harvey, and NSU’s Oceanographic Center. It is one of only a few private organizations dedicated to science-based marine conservation.
As a result of fishing pressure (primarily for their fins and meat) mako sharks are listed as “vulnerable” on the IUCN Red List. Being able to track these sharks with satellite tags allows scientists to learn much more about their migration patterns throughout the Atlantic Ocean which will improve future management and conservation efforts.
On his blog, Dr. Harvey describes what the tagging process is like. Once they catch a shark, it goes something like this: “shark tail roped, carefully lifted into the boat, cover the face with a towel put the deck hose in its mouth.” Then the crew holds the shark down while one person attaches the tag to the dorsal fin and with any luck, the whole process takes just a few short minutes before the shark is released back in the water.
Over the course of the expedition, they successfully tagged three mako sharks — the first three mako sharks tagged in the Atlantic Ocean. You can follow the movement of the sharks in real-time on the GHRI interactive tracking website here.
