Abstract

Lampedusa is an island located on the northern edge of the Gulf of Gabés, one of the most important foraging grounds for both adult and juvenile loggerheads living in the Mediterraneans Sea. This project aims at investigating the movements of the neritic-stage juvenile turtles in this area.
