The Aquaponics research team at The Cape Eleuthera Institute has successfully hatched nearly two thousand tilapia eggs. Eggs were removed from the mouths of the female brood stock and transferred to a larval rearing device known as a McDonald Jar where they were maintained at a water temperature of 27°C. Tilapia are mouth brooders; upon fertilization of eggs the female scoops all of the eggs into her mouth and incubates them for 3-5 days. After spending four days in the McDonald Jar, the eggs had a near 100% successful hatch rate and transformed into fry. They have officially been introduced into the aquaponics system and are doing FANTASTIC!
I’m Grace Dennis, one of the shark interns for the summer. I’m from Houston, TX and study Environmental Biology and Economics at Colgate University. This is my third summer on Eleuthera and I love it here. I first came to the Island School as a student for Summer Term 2010, then again last summer as a shark intern to work on the nurse shark mating project. This summer I’m lucky to be working on all three shark projects, the nurse shark mating project, Ian’s lemon shark predator and prey project, and Edd’s stress physiology project.
Currently shark team is very excited about retrieving a satellite tag, which just spent 8 months on a reef shark. Continue reading →
Hello! My name is Chris Daniell, Shark Intern and IS alum, and thank you for reading my blog post!
Being a student at the Island School was the most amazing experience of my life. I was here in the fall of 2010, and I spent the majority of 2011 trying to return. And here I am, living on Eleuthera, and living the dream.
The three months I spent as an Island School student were the best of my life. I loved every aspect of life here, from the more environmentally conscious nature of life, learning new things and meeting new people, and exploring the island of Eleuthera. However, my favorite part of The Island School experience was the connection to the ocean. My life has been dominated by a love for two things: science and the creatures that inhabit the world’s oceans. The Island School gave me my first hands-on experience with marine science, and gave me the opportunity to work with marine biologists. I was placed Continue reading →
As a Systems Intern at CEI this summer, I will work with Matt Poss, Sam Kenworthy and other members of the facilities team for the next two months. Although my main project this summer will be CEI’s biodiesel production, I will also help out with other projects that need an extra pair of hands.
At the moment we produce working fuel but don’t really know what quality it is. It’s easy to make biodiesel that seems to work well but has contaminants in it which relatively quickly destroy engines, are hazardous to the brewer and user, and which can actually be worse for the environment than petrodiesel. So having a clue about the quality of one’s product, as well as its various byproducts, is quite important! There are a lot of tests to which commercial biodiesel producers have to submit their product, but they generally require extremely costly equipment or highly trained analytical chemists, and- at least at the moment- cannot be carried out here on Eleuthera. Over the next few weeks I will therefore research different tests we can reasonably do for every batch of diesel we produce and begin to use these tests on our feedstock oil and the diesel we make. This will allow us to ensure that our vehicles run smoothly and give us an idea of how the quality of our biodiesel varies from batch to batch, which in turn will allow us to improve our production process. So far I have worked only briefly with Marco Continue reading →
Hey Everybody! My name is Drew and I am an Aquaculture intern at CEI this summer. I’m from Maryland and just graduated from high school in DC; I will be attending Bowdoin College in Maine this fall where I hope to study Biology and English. In the past I have volunteered/interned at the Smithsonian’s Natural History Museum and National Zoo. My specific interest is in Invertebrates, so it’s a change of pace for me to be working with fish! At the museum I worked primarily with deep water invertebrates that were pulled from Lophelia reefs in the Gulf of Mexico collected before and after the oil spill in 2010, all in hopeful preparation for some comparative analyses, and I worked at the Zoo in the Invertebrate exhibit maintaining some of their tanks. In my spare time I like to work on my marine aquarium, whitewater kayak on the Potomac, read, and explore the Appalachian mountains.
If you are not already aware, the aquaculture team (Marie, Tyler, and I) with the help of a lot of other awesome CEI people transferred our cobia to the offshore cage. For the past week or so we have been making daily dives on the cage to feed the cobia Continue reading →
We are thrilled to have UNC-Chapel Hill Morehead-Cain scholar Stephan Grabner with us this summer! Stephan joins us as the CEI Systems Intern on his third summer of the four-summer Morehead-Cain summer enrichment program. Though Stephan is a philosophy major at UNC, he will be helping Marco with biodiesel production this summer at CEI.
How does a philosophy major end up hands-on with biodiesel? For Stephan it is part of an interdisciplinary approach he is taking to find connections between sustainable development, ethics, and economics.
Stephan’s journey to Eleuthera has been a long one. Originally hailing from Vienna, Austria Stephan went on to high school at the United World College of the American West in Montezuma, in New Mexico—a small international boarding school with students from roughly 100 countries. UWC nominated Stephan for the Morehead-Cain, which had only just been opened up to international candidates.
This week, 16 summer interns arrived on Eleuthera to work at Cape Eleuthera Institute. Of those 16, we were excited to welcome back 6 Island School alumni who spent a semester, summer term, or divemaster course here on the Cape over the last 6 years. Mackey Violich (F’06), Elizabeth Douglas (S’08), Jasmine Wilchcombe (F’08), Grace Dennis (Su’10), Chris Daniell (F’10) and Jake Verter (S’09) will be here supporting the Shark and Aquaponics programs for the next two months! We’re glad to have you back!
This spring, two high school seniors, Louise Shiverick (F’10) and Sam Falkson, came down to Eleuthera to work at the Cape Eleuthera Institute for their senior project. Read about their time at CEI working with the lemon shark program.

Louise
My name is Louise Shiverick and I am lucky enough to be working at the Cape Eleuthera Institute with the Shark Research and Conservation Program for my Senior Project. At my school, Hathaway Brown (in Shaker Heights, Ohio), the last thing that the seniors do before graduating is a two week senior project. The point is to give us one last opportunity in high school to get involved with something that we find really interesting. People do a variety of things, from community service at soup kitchens to shadowing a doctor at one of the nearby hospitals. While most people stay at home, I decided to do something different and come to CEI.
I was an Island School student in Fall 2010 and was on the Lemon Shark research group Continue reading →
Last week, the nearby settlement of Deep Creek had their annual homecoming called Conch Fest. The Cape Eleuthera Institute (CEI) set up a booth amongst all of the conch fritter and local craft stalls at Conch Fest to give information and answer questions about CEI and Island School, as well as play a few games with the children who stopped by the booth. Here are a few pictures of the booth at Conch Fest.
The past two days have been primarily taken up with learning about and surveying green sea turtles in the local sounds and creeks. We began yesterday with a mini-class taught by Lucie, a researcher at CEI completing a baseline survey on turtle populations in South Eleuthera. We learned that there are 5 different species in the area–Green, Olive Ridley, Loggerhead, Leatherback and Hawksbill–though some are more abundant than others. All of the species are protected under international treaties, though very little is known about their populations, migratory habits, etc.
After learning about the turtles and how Lucie conducts her studies, we headed out to Jack’s Bay to do our first survey. We hiked in to the beach and got picked up to go out to the seagrass beds where the turtles usually hang out. Spotting turtles requires two people to stand on the bow deck of the boat and look in the seagrass for turtles. It is not an easy job, but once we all saw one turtle, it was much easier to spot them. We saw a few from the boat (and we were all really excited!), but when we got in to snorkel with them, they had all disappeared! We were a little bummed to miss swimming with the turtles, but Lucie assured us that the next day would be even better at Half Sound.
