Many of the larger commercially fished shark species are highly mobile, with some species known to make transoceanic migrations. Understanding the movement patterns of sharks is essential for effective management, and for designing the spatial extent of marine reserves to optimize conservation of these ecologically pivotal and mobile apex predators.
The GHRI, in collaboration with the Marine Programs Division of the Wildlife Conservation Society, is using a combination of field telemetry tracking, satellite tracking and genetic approaches to assess the short and long-term movement patterns of sharks. The current focus of this research is on determining movement patterns of blue sharks ( Prionace glauca) globally and Caribbean reef sharks ( Carcharhinus perezi) in relation to marine reserve boundaries in Brazil ( Fernando de Noronha archipelago) and Belize (Glovers Reef).
