Incidental Capture of Loggerhead Turtles (Caretta caretta) on Boa Vista (Cape Verde Islands)

Abstract

The sea is one of the major natural resources of the Cape Verde Islands, a small archipelago located 500 kilometers off the coast of Senegal (West Africa). This country consists of ten main islands and several islets, and possesses an Exclusive Economical Zone (EEZ) of about 734 square kilometers and a coastal perimeter of nearly 2000 kilometers. The marine shelf, whose limit is the 200 m isobath, is particularly extensive on the island of Boa Vista (Figure 1). lt is likely that most of the loggerhead turtles (Caretta caretta) that breed in this archipelago are concentrated on this island (López-Jurado et al., 1999).
