A green sea turtle will be released Friday from Lido Beach after nearly a year of care in Mote's Sea Turtle Hospital, which remains over-full due to a recent surge in turtle strandings. The 21-pound juvenile green sea turtle (Chelonia mydas), nicknamed Fisher, will be returned to the sea between 9 and 9:30 a.m. on April 16 near the lifeguard tower at the north end of Lido Beach.

Fisher was brought to Mote by members of the public after stranding in rough surf on Siesta Key on June 30, 2009. The turtle responded well to medical care, fluids and an appropriate diet, but Fisher had a persistent infection requiring antibiotics through mid-March, 2010.

Once the infection cleared up, all Fisher needed was a healthy tan - the turtle's long hospital stay had left its skin and shell light-colored, which could pose a problem in the wild.

"Green sea turtles can lighten up dramatically if they stay out of direct sunlight, and that leaves them vulnerable to sunburn," said Lynne Byrd, Mote's Animal Care Coordinator. "We like to give them a little base tan before they go back to sea."

After Fisher's release, Mote's Turtle Hospital will still be caring for 19 sea turtles - nearly double its normal capacity. Patients include 17 green sea turtles and one Kemp's ridley sea turtle (Lepidochelys kempii), both endangered species under federal law, along with one loggerhead sea turtle (Caretta caretta), a threatened species.

Nine of Mote's current patients have fibropapillomas - a type of tumor caused by a virus that can disable or even kill sea turtles. Mote is one of only three facilities in Florida that can treat turtles with papilloma tumors.

Mote staff are still caring for several turtles stunned by January's unusually cold temperatures, which affected more than 4,500 turtles statewide, though most of Mote's cold-stunned patients have been released.

But several new patients have arrived since the cold weather abated, including six in March alone.

"The strandings we're seeing now may be caused by delayed effects of the cold weather," said Gretchen Lovewell, Manager of Mote's Stranding Investigations Program, a 24-hour response service for stranded or dead marine life in Sarasota and Manatee County waters.

The Program has responded to more than 90 reports of stranded or dead sea turtles so far in 2010, compared with 58 for all of 2009. "Turtles were likely debilitated by the cold, which could make it harder for them to bounce back if they have another health problem," Lovewell said. "We've also seen several turtles with injuries from boat strikes."

As weather warms, turtles may be more vulnerable to boat strikes as they float at the surface to bask in the sun. In addition, adult female sea turtles are now making their way toward southwest Florida shores for nesting season, which runs from May 1 to Oct. 31.

Mote staff ask boaters to keep our waters turtle-friendly by following Coast Guard-approved safe boating guidelines and using vigilance to avoid striking sea turtles.
