Sažetak
Data collected between 1 April and 15 May 1996, and during implementation of Cape Verde Humpback Whale Project are presented. Three species of marine turtles were recorded: loggerhead turtle (Caretta caretta), hawksbill turtle (Eretmochelys imbricata) and leatherback turtle (Dermochelys coriacea. Results of the beach survey show that loggerhead females lay eggs on Sal Island, although the actual size of their nesting population is unknown. Along 30 km of sandy beaches, remains of more than 40 loggerheads were found, mostly heavy injured (bone and scull fractures, decapitations), obviously by humans. According to the local inhabitants, marine turtle females are constantly slaughtered during the eggs-deposition. They are mostly used for consumption. Three major threats on marine turtle nesting population at Sal should be emphasized: (I) loss of nesting beaches due to tourism development ; (ii) exploitation of nesting females, eggs and hatchlings, and (iii) incidental catch. Data on loss of eggs and hatchlings caused by natural predators do not exist. All species of marine turtles on Cape Verde Islands are legally protected. Nevertheless, human impact on their population is still out of control.Therefore, research and conservation program is urgently needed.
