Head-start wild-caught reptiles for release: Sea turtles
A replicated study in 1967–1974 in pelagic waters in the Caribbean Sea near Bermuda (Burnett-Herkes 1974) found that some head-started and some accidentally-caught immature green turtles Chelonia mydas survived at least several months after release in the wild. In total, 16 of 108 (15%) released head-started or accidentally-caught immature green turtles were recaptured. Nine turtles were recovered within 10 months, other recaptured turtles had spent up to 27 months in the wild. Most turtles were recaptured a few hundred metres to 14 km away from their point of release, except for one head-started turtle that was recaptured 2,315 km away from the release site after 10 months. In 1967–1971, eighty-nine green turtles were head-started in Costa Rica and released after approximately two years on the north and south coasts of Bermuda. In addition, 19 wild-born immature green turtles caught accidentally by local fisherman were tagged and released as part of the same programme.
