Studying the knowledge and consumption of lionfish on Eleuthera

Red Lionfish (Pterois volitans) is a venomous species that has been invasive to The Bahamas for over a decade (since 2004). It was first observed around Eleuthera in 2005 and has since become established around the island and its neighbouring cays. Research has shown that the impact of their invasion has and will continue to have detrimental impacts on marine habitats, especially coral reefs. Due to their voracious appetite and rapid reproduction (potentially up to 2 million eggs per year!), they have the potential to decrease commercially fished species’ populations and alter ecosystem processes e.g food webs. Their ability to do so has been aided by the naiveite´ (unfamiliarity with lionfish) of native fish and the fact that lionfish have no natural predators in Western Atlantic waters. As such, Cape Eleuthera Institute has promoted consumption of lionfish in an attempt to introduce it as a commercially consumed fish. This summer Newcastle University student Myca Cedeno has been conducting a social science study aiming to determine the spread of knowledge Eleutheran residents have on lionfish and consuming them as a means of managing their invasion and contributing to food security.

In April 2014, CEI introduced a Lionfish Slayer campaign, encouraging members of the public to spear lionfish in return for payment; a venture which was met with success. This summer Myca has advertised this campaign and worked to inform Eleutheran’s about lionfish’s nature as a “venomous” and not a “poisonous” species. Through interviews he has documented the views of the public on safely consuming this invader given their deleterious effects on the reefs. Myca has been in the field interviewing fishermen, restauranteurs and other members of the public as part of his dissertation research. His data collection is also coupled with educational outreach, as each interviewee is left with a flyer, detailing the history of the invasion, why it is safe to consume (despite its venomous spines), how to handle and prepare it and what to do if stuck by a spine.

So far, it’s nature as a venomous species has been a major deterrent to consumption for consumers and catch by fishermen. Restauranteurs have highlighted a lack of availability of the lionfish, potentially linked with the apprehension of fishermen to catch them. It is the hope that this research and outreach effort will help further educate the public as to the value of eating red lionfish and will provide insight as to how best to further promote this venture.

Patch reef survey time!

Last week the Reef Ecology and Restoration team completed the March monitoring surveys of the 5 year reef study around the patches of Eleuthera. The March surveys usually call for thick wetsuit, hoods and hot chocolate. However, the water was particularly warm at 27oC, resulting in the surveys being completed in record time. Dr Jocelyn Curtis-Quick has been leading this study since 2012; she now plans to use this incredibly unique and invaluable dataset to thoroughly examine the influences and impacts that the invasive lionfish have on the patch reef ecosystem. Every part of the reef is searched for lionfish

The Reef Ecology team has already begun the process of analysis, and Jocelyn was able to present some of these preliminary findings at the Bahamas Natural History Conference in Nassau earlier in the month. By continuing to spread and enhance the local knowledge within Eleuthera and beyond, the management of the lionfish will hopefully continue to grow.

Removing lionfish from the reef

Of the 16 patches that have been surveyed throughout the study, 8 have been designated as removal sites, and with a highly experienced team we were able to continue our contribution to the culling effort around The Bahamas and wider Caribbean. Stay tuned to hear the full results of our study and a more detailed picture of how the lionfish is making its presence felt around Southern Eleuthera. In the mean time don’t forget, You Slay, We Pay!

Lionfish: Island School’s favorite dish!

The invasion of lionfish on reefs of the West Atlantic has become an issue of critical concern.  With eradication not possible, the silver lining is that lionfish are delicious. The You Slay, We Pay campaign was launched by Dr. Jocelyn Curtis-Quick to support the development of a local lionfish market in The Bahamas. The Island School bought lionfish from local Bahamian fishers to consume in the dinning hall. Rock Sound Lionfish Slayers wearing their well earned slayer t-shirts

The slayer campaign initially ran through lobster closed season in 2014, as this is the time of year that many fishers will switch to conch harvesting, which is less lucrative as a fishery and increases pressure on the already overfished species. This trial lionfish season was so successful that in December of 2014 (during the closed grouper season) the lionfish You Slay, We Pay was launched all year round.  Over 1500 lbs of lionfish were brought in throughout 2015, with new fishers joining regularly and more lionfish meals being enjoyed on campus. We hope that 2016 sees even more lionfish removed from the reefs and on the plate.

Lionfish, and conch, and sea turtles, and aquaponics, oh my!

Last weekend, programs from the Cape Eleuthera Institute, including the Reef Ecology and Restoration Team, Sustainable Fisheries Team, Sea Turtle Team, and Aquaponics Program travelled to Governor's Harbour Homecoming to spread the word about each of their fields.

Many people showed great interest in the lionfish and aquaponics displays. They were amazed at the use of plants to filter the fish waste out of water holding tilapia in the aquaponics system, while others who had never tried lionfish fritters are now converts!

The Sea Turtle Team and Sustainable Fisheries Team also educated the attendees about the protection of sea turtles through some fun word games, and the life stages of conch through a display with varying sizes of shells, ranging from juveniles to adults.

 

Halloween Spooktacular- Lionfish Treats

The spooky lionfish tank! On the night of Halloween, the CEI team put on their lionfish costumes and travelled to the Spooktacular event at the Leon Levy Native Plant Reserve in Governor’s Harbour. The team continued to spread the word about the lionfish invasion with spooky red lights illuminating a tank showcasing a live lionfish, and dyed blue, green and red fritters.

Spooky lionfish treats were a big hit at the Leon Levy Halloween event

Batman, Spiderman, witches and several zombies came to view the illuminated invasive lionfish, and were served the spooky and tasty lionfish fritters. Those who had never tasted lionfish before enjoyed the delicious fish and gave great feedback, stating they were tastier than conch fritters, even when they were green inside! Next weekend the team will be setting up a booth at the Governor’s Harbour Homecoming, and hope to continue our long term goal of seeing lionfish not just at outreach events, but permanently on restaurant menus throughout The Bahamas.
