The Island School is on Google Maps Street View!

The Island School is excited to announce the launch of Island School Street View!  You can now take virtual tours of The Island School, Cape Eleuthera Insitute, and Center for Sustainable Design campuses, as well as iconic locations around the Cape as if you were there!   To move througout the tours, pan around the "photosphere" and click on the hovering arrows or circles located on the screen.

The Island School Campus Tour has six locations throughout the tour: The Flag Circle, Entrance, Boathouse, Dining Hall, Boy's Dorm, & Boy's Dorm Beach.
Cape Eleuthera Institute has four locations: CEI Entrance, The Wetlab, CEI Walkway, & Hallig House.
The rest (DCSM, The Sand Bar, The Offshore Aquculture Cage, Cathedral Rock, Scuba Class on the Cobia, and Weirda Bridge) can be found on main Island School profile page on Google Maps.

SP'12 Human Ecology Project on CEI's Aquaculture Program

At the conclusion of every semester, Island School students break into small groups to focus on a single final Human Ecology project based on an particular interested that has developed throughout the semester. Spring 2012 students Brendan James, Liz Ellinger, Paul Henderson, and Kyle Forness studied the Cape Eleuthera Institute's Aquaculture program and its history and created an informational and professional video for educational purposes. Check it out! http://www.youtube.com/watch?v=2ZjmsOCj-B8

Cobia Moved to the Aquaculture Cage!

http://www.youtube.com/watch?v=omqXE31qC0w&feature=youtu.be The aquaculture program here is running essentially a model system for the commercial aquaculture industry; we aim to display that (delicious) carnivorous fish, cobia in our case, can be farmed in the Bahamas in an ecologically and economically sustainable fashion. Just last week we moved all of the juvenile cobia (around 1,000 fish) from the wet lab into the cage, which was quite an impressive feat. I don’t know why little fish would fight going into a huge shark resistant cage in the ocean to be fed every day, but fight they did. Though, with the help of pretty much the entire staff here at CEI the process went very smoothly. While one team transferred the cobia to two 1,400 L (~400 gal) totes to be anesthetized with clove oil, another team prepared another two totes onboard the aptly named research vessel, the Cobia, and waited at the marina down the road. The initial two totes were driven over, and the fish were transferred with nets to the totes on the Cobia. Some of the fish didn’t feel like consuming the clove oil and being calm apparently, so this part was very slippery and prickly (cobia have spines) for us humans. All the fish were moved safely though, and we drove the boat out to the cage.

In order to put the fish in the submerged SeaStation cage, we crafted a “toilet” of sorts: a bucket with a hole in it was affixed to the top of a long tube about 6” in diameter which went down through the zipper of the main net and into a nursery net inside the cage. Using a pump, water was spiraled down the bucket and tube, and the fish were “flushed” from the boat one by one into their new home. The last couple days we’ve been diving and feeding the fish, who are still learning that big scary divers are giving them food, but they seem to be doing perfect and there are no mortalities to note. Here’s to a successful growout!

New Shark Resistant Netting on CEI's Aquaculture Cage

This fall the Cape Eleuthera Institute installed a new shark-resistant netting called PREDATOR-X on CEI's off-shore aquaculture cage. The netting was developed in partnership with NET Systems, Inc., and DSM Dyneema. This video provides an inside look at the research and development process, as well as the installation. http://www.youtube.com/watch?feature=player_embedded&v=bPe5LIiqVV0

More Baby Fish Have Arrived!

On Friday, January 27th half a million eggs arrived from Miami, Florida! They were placed in an incubation tank, where they hatched early Saturday morning. To the naked eye they looked like pieces of rosemary floating in the water. But under the microscope you could see the egg sack that was encased around the head and the tail was sticking out. The bottom of the tank was siphoned in order to get rid of the unhatched eggs and dead larvae. This is very important because if they were left in the tank bacteria can grow, which can kill the larvae. After determining how many larvae were alive, they were then transferred into six larval rearing tanks. They will obtain their food from their egg sack for three days. Cobia develop after they hatch, which means their mouths are very small and in turn can only eat rotifers for the first couple of weeks. They will eat enriched rotifers for about three weeks and then move onto eating artemia for another 45 days. Once they start growing more we will be able to wean them onto dry food and then eventually bring them out to the offshore cage that is fitted with shark resistant netting that was donated by DSM Dyneema!
