The mitochondrial control region was analysed for the population genetic structure of Cuban population of the hawksbill turtle, Eretmochelys imbricata. Among 30 haplotypes detected in a 480 bp fragment of the mitochondrial control region for 218 individuals in the Caribbean region, dominant haplotype in the Cuban nesting population was CBI, in company of CB2, CB3 and CB4, showing that the Cuban nesting population has an specific genetic markers. Contribution rates for the foraging samples from Doce Leguas at Zone A (south-east shelf) was 67%, indicating that the majority of hawksbill turtle migrate around a home range near the nesting site. It is interesting that the contribution rates were decreased remarkably from Zone A to Zones B at south-west shelf (43%) and D at north-east shelf (41%). The contribution rates in Zone B showed higher in Autumn (53%), than that in Spring (33%), which coincided to nesting season from September to December based on the presence of eggs in adult female individuals.
