Juvenile turtles recruit at Mantanani from their post-hatchling neritic drifting years at some 30 cm in CCL and reside there for some 5-6 years and they subsequently depart to secondary foraging grounds - presently unknown. This project will track small (40-60 cm CCL) green turtles as they depart Mantanani to identify the location of the secondary foraging areas. For conservation to be successful, we aim to inform governments and conservaiton agencies of the connectivity of marine habitats with this work.
