CEI Lionfish team visited Rock Sound’s homecoming celebration.  Amid stands selling fritters, grouper, and curry chicken the crew erected a booth dishing out free samples of lionfish ceviche, passing out brochures, and sporting the new line of t-shirts from CEI’s “You Slay, We Pay” campaign.  It is at venues like these, when huge numbers of people from around the Bahamas come together to celebrate, talk, and most importantly eat, that outreach is so critical.  It is not yet universal knowledge that lionfish are both edible and delicious, so having a presence at local cultural events such as this allows us to spread awareness and change minds.

This was evidenced first hand on Saturday, when many locals tried lionfish for the first time. Initially hesitant observers came forward after hearing about the process of safely filleting lionfish, discussing the benefits to many native fisheries from eating lionfish, and seeing the satisfied smiles of previous samplers.  Many first-timers were visibly surprised at the clean taste of the white meat.  The unanimous consensus was that the fish offers a delicious alternative to other Bahamian classics.

Why is this so exciting and why is outreach like this so important? The invasive and hugely harmful lionfish is a largely untapped marine resource throughout the Caribbean. However, with more and more people trying and loving lionfish at events like Saturday’s homecoming, it is hoped that demand for lionfish as a fishery will rise.  Fishermen will then play a greater role in lionfish population control as they work to meet that demand with supply.

 

How to make your own lionfish ceviche:

 

1.         Start with fresh lionfish fillets, and finely dice.  Immerse in lime juice for 20-30 minutes.

2.         While lionfish is marinating, dice green peppers, tomatoes, and onions. Place in a bowl to the side.  You should have roughly equal amounts of vegetables and fish.

3.         Dice a very small amount of habanero or scotch bonnet pepper into extremely small chunks.

4.         Drain lime juice out of the lionfish; fish should look opaque and white.

5.         In a large mixing bowl, combine chopped fish and all vegetables and peppers.  Mix well, season with salt and pepper to taste.

6.         Serve and enjoy!  You are promoting a sustainable fishery.

Effect of Thermal Stressors on Great Barracuda and Schoolmaster Snapper

GOPR0760
Conducting a swim trial with a Great Barracuda

Over the next 100 years, factors causing climate change have the potential to increase sea
surface temperatures by up to 5 degrees Celsius.  However, even a small increase could have
drastic effects on tropical areas due to the historical thermal stability of places such as the
Caribbean.  Recently, the Cape Eleuthera Institute has been focusing efforts on investigating how
climate change may affect tropical fish species and the marine communities with which they
interact.  One specific project is using a swim tunnel to measure the aerobic scope of Great
Barracuda (Sphyraena barracuda) and Schoolmaster Snapper (Lutjanus apodus).  A swim tunnel
is a cylindrical tank in which a fish swims against a current and its oxygen consumption can be
measured.  Data obtained from the swim tunnel such as swimming velocity and respiration rate can then be used to calculate the fish’s aerobic scope.  Aerobic scope, or the capacity for oxygen­driven metabolism, is a good overall indicator for performance and can estimate how much energy a fish has to devote to essential behaviors such as foraging, predator evasion and reproduction. The water that flows through the swim tunnel can be slightly warmed to simulate future ocean
conditions, and the fish’s response can be quantified.  Through this study, CEI and the Flats
Ecology and Conservation Program hope to gain insight on how different coral reef and mangrove
fish species will react under the thermal stressors that climate change may present.

A coral nursery at CEI!

Scientists from the University of Miami, Rosenstiel School of Marine and Atmospheric Science, and the Atlantic Oceanographic and Meteorological Laboratories, NOAA, visited CEI to install a coral reef nursery on Cape Eleuthera.

Dr. Ian Enochs and Francesca Forrestal, PhD candidate (RSMAS), who is an Island School alum and sits on the CEIS foundation board, made the initial connection between the various institutions that resulted in this exciting opportunity. Dr. Diego Lirman and Stephanie Schopmeyer (RSMAS) have installed and studied staghorn coral (Acropora cervicornis) nurseries in Florida and throughout the Caribbean and were able to offer their expertise to the research team at CEI, through funding from Counterpart International. Over the course of two days, two nursery trees were set up at a local dive site and wild staghorn fragments were collected from local colonies. These fragments will be left in the nursery to grow and the nursery will hopefully be ready for expansion in the next 6 months. The goal is to be able to outplant these fragments next year and help restore wild populations of staghorn on Eleuthera. Staghorn – a major reef-building coral – has suffered major decline in recent decades and was listed as critically endangered in 2008 by the International Union for Conservation of Nature (IUCN). Restoration efforts are critical and the new nursery at CEI will also help raise awareness with all our visitors about the threats facing coral reefs globally. Visitors will be able to snorkel and dive the site and assist with maintenance – we’ll keep you updated on how the grow out goes!

NSF site visit to CEI

A group of biologists from Universities throughout the United States gathered to discuss the improvement of the research facilities at the Cape Eleuthera Institute (CEI).  This meeting was funded by a National Science Foundation planning grant written by PI Dr. Bill Louda (Florida Atlantic University) and Co-PIs Dr. Dave Philipp (University of Illinois), Dr. Brian Lapointe (Florida Atlantic University), and Aaron Shultz (CEI).  The expert panel, along with their individual research interests, is listed below.  The three day meeting started off with a tour of The Island School and CEI campus, and an excursion to some of the natural points of interest on the island.

DSC07559_resizeSeveral group meetings were held to discuss other research stations in the region (E.g., Central Caribbean Marine Institute, Florida Keys Marine Lab, etc.), current research projects at CEI, how to diversify the research portfolio at the institute, and the infrastructure needed to meet current and future demands.  The following are highlights from the discussions: the need for an ecosystem based approach to our research initiatives; the need for water quality analysis; and more lab space for visiting researchers and graduate students.  Overall, it was a very productive site visit that will aid in the development of the full NSF laboratory improvement grant.  CEI looks forward to collaborating with these researchers in the future.

The Bahamas Bull Shark Project

Bull Turn

The bull shark (Carcharhinus leucas) is one of the most infamous sharks in the world’s oceans.  They have evolved to hunt large prey in shallow coastal waters and, as a result, are thought to be responsible for more interactions with humans than any other species.  Consequently, this species is commonly portrayed in the media as the archetypical ‘killer shark’; however, the reality is very different.  Indeed, bull sharks regularly interact with divers without incident, and there are many places in the world (e.g. Mexico & Fiji) where shark dive operators regularly feed bull sharks for the tourist industry providing non-consumptive economic value for this species.

Despite its infamy and economic importance in some areas, the bull shark remains one of the least studied species of large shark in the greater Caribbean region.  Basic information relating to its biology and ecology is lacking, making any form of management virtually impossible.

DCIM102GOPROThe Shark Research and Conservation Program at the Cape Eleuthera Institute, in collaboration with its partners Microwave Telemetry Inc. and The Cape Eleuthera Resort and Marina, recently completed the first phase of its bull shark satellite-tagging program.  Five x-tags have been deployed on mature female bull sharks 246 – 291 cm (8.0 – 9.5 ft) in length which will log water temperature, depth every two minutes, and the approximate location of the animal every day.  The x-tags are pre-programed to remain attached for 6 or 9 months and when they start to pop-up in August 2014; the data will be transmitted via satellite back to the research team.

Bull Shark X TagThe bulls sharks encountered at Cape Eleuthera usually arrive in October-November when the water temperature starts to cool, and are commonly sighted in the marina until spring where they compete with the nurse sharks and snapper for fishermen’s discards.  An interesting characteristic of this aggregation it is entirely composed of large mature females, the most important reproductive component of any population.  A male has yet to be seen at Cape Eleuthera.  Bull sharks pup in freshwater or estuarine areas, a habitat which is almost completely absent in The Bahamas and Turks and Caicos Islands, suggesting that these animals’ migrations will take them north to Florida, or perhaps south towards Cuba, Haiti or the Dominican Republic in search of a safe place to give birth to their pups.  The data from these tags will help us to understand where this important demographic go when the leave Cape Eleuthera and hopefully help solve this mystery.

You Slay, We Pay!

spearsThe ‘You Slay, We Pay’ campaign is underway. Lionfish are invasive and devastating reefs; fortunately for us, they are delicious! However, these fish are still an untapped sustainable marine resource. The Island School with CEI launched a campaign to start a lionfish fishery and are buying lionfish from local fishermen for $11/lb during this lobster closed season (April 1st – July 31st). Locals fishermen are encouraged to bring fish in – they receive an amazing lionfish slayer t-shirt when they drop off their first 15 lbs of lionfish. Additionally, we enter them in a raffle each time they bring in 15 lb of lionfish, and there will be a prize draw at the end of season to win a new pole spear and other goodies.

So how can you support this campaign? Several ways:

Eat lionfish! Please, when you are eating out, ask for lionfish! Even if it is not on the menu it is a great way to create a demand and therefore supply. * Don’t choose to eat species that are in closed fishing season or are unsustainable.

INVASION AT BAYBuy a t-shirt! The purchase of your t-shirt supports the cost of ‘YouSAVE A LOBSTER Slay, We Pay’ sustainable fishery campaign. These limited edits shirts are available online now!

Update on Acoustic Tagging Project: Grand Bahama Jan 2014

A team of scientists consisting of Aaron Shultz and Malcom Goodman from the Cape Eleuthera Institute, David Philipp and Julie Claussen from the Fisheries Conservation Foundation, Karen Murchie from College of the Bahamas (Freeport), and Greg Vincent and Jason Franklin of H2O

Bonefishing from Grand Bahama gathered in Freeport in January to track bonefish movements. This project began in October 2013, when 30 bonefish from around the island of Grand Bahama were captured and implanted with acoustic tags. Electronic receivers were then placed in strategic locations throughout the island and recorded if a tagged fish swam nearby.  Fish were also located periodically using a manual receiver.

The first goal of this trip was to retreive each of the receivers and download the data to determine if any bonefish had been recorded. January, however, is still early in the spawning season for bonefish, so that data recorded over the next few months is expected to be highly valuable in understanding bonefish movements and the habitats they use for spawning.  The second goal was to use the manual tracking device to determine if bonefish were travelling to possible spawning locations around the new moon.

This early retrieval of data from the receivers was very encouraging, with several of the tagged fish being detected.  Two fish with transmitters, likely travelling to spawning locations, were recorded
traveling from one side of the island around to the other and back again, one covering over 140 miles roundtrip.  Greg and Jason from H2O Bonefishing were instrumental  in  finding schools of bonefish to see if tagged fish could be located using the manual receiver. Many fish were
located very near where they were tagged.

Scientist Karen Murchie will be analyzing the movement data from the project, and many thanks to her for providing housing and logistical support during the trip.

Spring 2014 Gap Year Conclusion

The Spring Gap Year program concluded this past week after an intense past nine weeks here at the Cape Eleuthera Institute.

The students have been involved all over the organization and got their hands into literally everything. To cover all we have done would take a lifetime to explain, but after speaking with two of the students who graduated, there were some definite highlights.

13380943823_5b827c47ff_bThe students got to hang out with DCMS resource center every Tuesday and Thursday evenings. This consisted of them assisting students with their reading skills. Not only that though, the Gappers got to have meaningful conversations about their history, both personal and geographical that has impacted their experience tremendously, making them think differently about different aspects of life here in the Bahamas.

During the final week of the program we held a Triathlon that spanned around the cape; a ½ mile swim, followed by a 12 mile cycle and then finished with a three mile run. It was completed with smiles on faces, as we high-5’d the flag pole on IS campus. It was a triumphant moment as all the training of the past nine weeks paid off.

As these students leave behind a legacy for the next Gap Year program, they embark upon different adventures around the globe. Learning more about the world and how they fit into it. We wish them all the best as their navigation continues.
