Many shark species appear to display a high degree of fidelity to very specific sites. The Migramar network is investigating the residency of these sites, and the degree of connectivity between sites. In this way, we can build up a model of spatial utilization for the different populations, and thus contribute to the management of protected areas (e.g. technical advice on coastal zonation processes around the islands).
By using the same technology at each Marine Protected Area, we are also able to determine whether tagged individuals migrate from one place to another.
