The hawksbill sea turtle (Eretmochelys imbricata) can be found in the Atlantic, Pacific and Indian Oceans. As with other sea turtles species, hawksbills have a cluster of scales on the dorsal and lateral surfaces of the head that form unique scale patterns. Following a previous study using Interactive Individual Identification System (I3S) Spot, we used the Pattern version of I3S to compare and identify in-water photographs of turtles within the Roatán Marine Park (RMP) on the western end of Roatán, Honduras from May to September, 2014. The Pattern program is designed to annotate individual ‘fingerprints’ for species with complex markings ...

The Protective Turtle Ecology Center for Training, Outreach, and Research, Inc. (ProTECTOR) works to increase the conservation of, and research on sea turtles in the country of Honduras. Efforts were made this summer to record the sightings of sea turtles in Roatán, specifically in the area of West End and the Roatán Marine Park (RMP). We worked in tandem with 13 dive shops in West End from June 9 – August 8, 2014 to collect dive sightings data. We prepared turtle sighting record sheets that prompted observers to record their name, the dive site and depth of each turtle sighting, along ...


Does Recreational Diving Impact Hawksbill Sea Turtle Sighting Rates? Preliminary Analysis For A Marine Protected Area, Honduras, Christian Hayes, Dustin S. Baumbach, Marsha K. Wright, Linda Baeza, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar Apr 2015

Does Recreational Diving Impact Hawksbill Sea Turtle Sighting Rates? Preliminary Analysis For A Marine Protected Area, Honduras, Christian Hayes, Dustin S. Baumbach, Marsha K. Wright, Linda Baeza, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar

Recreational diving is a form of ecotourism that is traditionally viewed as an ecologically sustainable activity prompting increased awareness for the marine environment. Still, recent studies indicate that recreational diving may cause increased spatio-temporal variability within coral ecosystems and unintended behavioral changes in marine macrofauna. Few studies however, have looked specifically at the effect of recreational diving on sea turtles. The purpose of this study was to determine if differences in dive site use and habitat composition can affect the rate of Hawksbill sea turtle (Eretmochelys imbricata) sightings in a marine protected area. From June 3 – August 31, 2014 we ...


Potential Hawksbill Prey Item Distribution Among Dive Sites In A Marine Protected Area In Roatán, Bay Islands, Honduras, Christian Hayes, Marsha K. Wright, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar Apr 2015

Potential Hawksbill Prey Item Distribution Among Dive Sites In A Marine Protected Area In Roatán, Bay Islands, Honduras, Christian Hayes, Marsha K. Wright, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar

The Bay Islands of Honduras consist of three different islands, one of which is the island of Roatán on which the Roatán Marine Park (RMP), a marine protected area, is located at the west end. The RMP has only recently become an important area for sea turtle populations. The marine park is patrolled daily by park rangers to prevent illegal fishing practices, and the take of sharks and turtles, creating safe foraging areas for many marine megafauna. Hawksbills have been observed foraging within the park, yet the prey species they utilize are essentially unknown. We observed hawksbill foraging behavior for ...
