Rehabilitated sea turtle released in Florida Keys to join Tour de Turtles

A juvenile green sea turtle rehabilitated at the Florida Keys-based Turtle Hospital was fitted with a satellite-tracking transmitter and released Friday to join an online race that follows long-distance migrations of sea turtles.

The Tour de Turtles, now in its 16th year, is organized annually by the Sea Turtle Conservancy. Beginning Aug. 1, the group will track a dozen sea turtles released from beaches in Florida and several Caribbean islands.

“The Tour de Turtles is raising awareness about sea turtles and the threats to their survival,” Sea Turtle Conservancy senior research biologist Dr. Dan Evans said. “We are also learning about where they’re going, where they’re finding food, and what the possible threats to those areas are.”

The young green sea turtle named Marcia, who was found floating off the Middle Keys in March, suffered from positive buoyancy disorder. The condition leaves sea turtles unable to dive down for food. Causes include internal infection, gastrointestinal tract obstruction and spinal or lung injuries, sometimes caused by boat strikes.

Officials at the Turtle Hospital treated Marcia, who weighs about 50 pounds (23 kilograms), with broad-spectrum antibiotics, fluids, vitamins and a diet of greens and mixed seafood.

“It’s really important to protect sea turtles like Marcia,” Turtle Hospital general manager Bette Zirkelbach said. “This tracking and the information it brings to scientists through Tour de Turtles is going to help this species survive.”

Green sea turtles are classified as “threatened” under the Endangered Species Act.
