37 Loggerhead Sea Turtles Introduced to Turtle Excluder Device

Federal biologists released 37 loggerhead sea turtles into the Indian River Lagoon, Florida, this week morning, about a mile south of Sebastian Inlet.

The turtles had been used in an experiment in Panama City, where biologists video record the turtles swimming through fishing nets to learn how best to design escape hatches in the nets that allow turtles to slip free.

Shrimp nets are one of the main causes of sea turtle deaths. The turtles drown in the nets when they can’t escape and reach the surface for air.


The 3-year-old turtles weigh 20 pounds to 30 pounds and were gathered as hatchlings in the Archie Carr National Wildlife Refuge.

The turtles were raised in Galveston, Texas, and then taken to NOAA’s Panama City facility for the net experiments.

It is hoped these excluder devices will become an integral part of saving sea turtles.  Loggerhead sea turtles are federally protected as a threatened species.

Bumper Crop of Pelican Chicks on Gaillard Island, Alabama

As this year’s crop of baby pelicans hatch out on Gaillard Island in Mobile Bay, biologists in Alabama are breathing a sigh of relief. At the midpoint of the first nesting season since the BP oil spill, the manmade rookery is housing a bumper crop.  At 1,300 acres, this island is one of the largest pelican nesting areas on the upper Gulf Coast.

I think there is an uptick in the number of pelicans out there, and maybe even royal terns. Overall, it looks like a great year, said Roger Clay, with the state Division of Wildlife and Freshwater Fisheries.

Back in the early 1990s, shortly after the island was created out of the dirt dug up to make the Theodore Industrial Canal, around 1,000 pairs of pelicans showed up to nest. This year, there are 4,000 to 6,000 pairs, along with more than 10,000 pairs of gulls, herons, ibis and terns.
 
The 8,000 pelicans are now raising around 16,000 chicks, while the 20,000 gulls and other birds are raising around 40,000 chicks, meaning there are more than 80,000 birds on the island.

 We can always throw that caveat that we won’t know for years if the spill caused a problem, but a good hunch is that in the short term, it doesn’t appear to have had an effect, Clay said last week.

He said nearly every kind of shorebird common in the state nests on Gaillard. The island is prime bird habitat for two reasons: there are no predators and there are no people.
