The Gulf's Great Turtle Relocation Project 104

An anonymous reader writes "All along the Gulf Coast's beaches it's turtle-hatching season. Conservationists knew the poor hatchlings wouldn't have a chance if they swam out into the oily waters of the Gulf, so they came up with an incredibly ambitious plan: they would dig up 70,000 turtle eggs, carefully raise them in a climate-controlled hanger at the Kennedy Space Center, and release the hatchlings into the clean Atlantic waters off Florida's east coast. Now that project is well underway, and Discover Magazine has pictures of the first batch of hatchlings crawling toward the welcoming waves. But there's a chance all this do-gooding won't do any good. New Scientist found experts who argue that releasing them into the Atlantic rather than into the Gulf will screw up the turtles' navigation systems, which will prevent them from following their normal migratory routes."

        Just about all turtles are endangered - there are a hell of a lot less of them now than there were a few hundred years ago. We've already fucked up the ecosystem by killing most of the turtles.... What most turtles eat (jellyfish) don't seem to be endangered at all - the lack of turtles and other predators seems to be increasing jellyfish numbers. Too many turtles is not going to wreck the ocean biosphere any time soon.

        Meh, it's not like they're moving all the turtles. They're just spreading them around a bit. Most baby turtles get eaten anyway (survival rate from hatching is something like 1/100?), so at worst they're expanding the culinary variety of wildlife out on the panhandle. So we're really talking about ~700 turtles that might reach adulthood, which isn't really all that terribly many in the scheme of things.

      Maybe they'll end up establishing new populations in different locations.
      It's certainly better to give them the chance rather than simply let them be exterminated.

      I think it's important to note that while 70,000 eggs seems like a lot, it comes from only 800 nests in two states. Turtles lay a lot of eggs, because most of them are not going to survive in any case.

      The point here is that they're hardly moving all the turtle hatchlings to the east coast, so if moving them is futile or even detrimental compared to leaving them in the Gulf, that'll be apparent in the outcome of the sea turtles that will hatch in the sands of the Gulf coast. On the other hand, if they have even a chance to survive in the Atlantic while the Gulf ends up being certain death for the turtles left there, then that's a huge win. The species occurs naturally on the Atlantic coast, so it's not like we're introducing a new species with potentially detrimental consequences.

      There's very little downside here, and the potential for a huge upside. The experts may be right that it is futile, but it is absolutely worth trying and I commend these folks for it.

    What are the potential outcomes of letting the hatchlings make their way into the polluted water?
        Turtles die of exposure to oil
        Turtles survive because all the predators have already died from the oil

    Seriously, I think that the people who have committed themselves to preventing a straight up die off of an entire generation of gulf-coast turtles should be commended as heros.

    fwiw, I hope that the 70K extra turtle on the Atlantic coast overwhelm the natural predators and allow more hatchlings to reach adulthood. Is there a chance that the introduced population could displace the natives? Possibly.

    His view is backed up by evidence that suggests turtles are programmed from birth to follow a specific migratory path once in water. Indeed, turtles from different nesting sites seem to inherit different sets of navigational instructions.

    Basically, in the past they have exposed turtles (in tanks?) to magnetic fields and found that they follow the magnetic fields as if they were navigating through the ocean. It kind of surprises me that no one has ever taken a turtle from Texas and put it in the ocean in Florida just to see what would happen. Here is their chance: hope they pay attention to what the turtles do.

    The same species that nest in the Gulf also nest on the East Coast of Florida which is oil free. The real issue is whether the built in homing instinct for nesting will be to the original nest or to the transplant nest from which they emerge. I have no knowledge of whether the issue has ever been studied. Either way it is still a big problem as the East Coast breeding grounds may not support additional nests as over population and erosion take their toll on natural conditions.
