Guy Harvey leads expedition to study Mako Shark migrations

Tagging onboard LR Guy Harvey Research Institute
The tagging and tracking of shortfin mako sharks in late March off the coast of Isla Mujeres, Mexico is expected to provide scientists with remarkable and previously unknown details about the timing and long-distance migratory movements of this vulnerable species in the Atlantic Ocean.

An expedition headed by the Guy Harvey Research Institute (GHRI) at Nova Southeastern University, tagged mako sharks with the satellite reporting SPOT tags. Unlike the more commonly used pop-up satellite PAT tags, SPOT tags should provide multiple and more accurate daily detections, providing scientists with a high resolution view of the migration patterns of this animal.

Given the high fishing pressure on makos for their fins and meat, this species is showing declining population trends in parts of its range, which has resulted in the species being listed as 'Vulnerable' on the IUCN Red List of threatened species.



Last year a shortfin mako shark dubbed 'Carol' in New Zealand was tagged with a SPOT tag and is showing an amazing journey that has covered nearly 9,500 miles over ten months, averaging 60 miles per day during some parts of her migration. GHRI collaborated with the New Zealand National Institute of Water an Atmospheric Research (NIWA) on the tagging of 'Carol' and three other mako sharks off New Zealand.

Internationally known marine artist, scientist and conservationist, Dr. Guy Harvey, who returned to Isla Mujeres for the second consecutive year, described the most recent expedition in his online blog, which can be found at http://www.GuyHarvey.com/guys-journal.

Shark biologist Dr. Brad Wetherbee with GHRI and the University of Rhode Island, angler and WTVJ NBC 6 weather anchor Jennifer Reeves and Emmy Award winning producer/cameraman George Schellenger accompanied Dr. Harvey. The team worked with Captain Anthony Mendillo of Keen M International.

Dr. Mahmood Shivji, Director of the GHRI at Nova Southeastern, said the newly tagged shark, named 'Jen' for Jennifer Reeves (who caught the shark), can soon be followed on a new website combining all tracking projects into one integrated portal.



'The public interest in GHRI’s shark movement research has been amazingly strong,' said Dr. Shivji, who reported that the New Zealand online mako satellite-tracking site has received nearly 73,000 unique visitors over the last seven months, equating to an average of over 10,000 unique visitors per month.

'We hope to replicate the tremendous success of our New Zealand research in the Atlantic,' said Dr. Harvey. 'Now we have a new group of Atlantic makos to follow which should reveal much new information on their seasonal movements in our part of the world, including the route that they take and distances traveled.'
