DELLY the green sea turtle has a couple more weeks to go and more weight to gain before she can be released from the Quoin Island Rehabilitation Centre.
Turtle supervisor Elidh Robb said the animals could spend up to a year at the centre, depending on their condition.
"It really depends on what is wrong with them," she said. "On average they spend two to three months.
"We've only got six turtles at the moment," Ms Robb said. "We've had a really good string of success, getting them back out really quickly."
QIRC will have its own stall at Ecofest on June 1 at the Tondoon Botanical Gardens.
The stall will have QIRC merchandise, displays, recycled craft activities and even a turtle on site.
With the turtles eating up to 5kg of lettuce and spinach a day, QIRC is asking for donations of leafy greens.
