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.

Lionfish outreach at Wemyss Bight Homecoming

Tasty lionfish fritters being prepared On October 10,  the CEI team headed to Wemyss Bight Homecoming to spread the word about the lionfish invasion. The team was armed with a large batch of lionfish fritters to give everyone the chance to taste these invaders.  The booth grabbed lots of attention from a large range of age groups, enticed by the live lionfish in a tank and the smell from the fritters! Most people had the perception that lionfish were poisonous and wanted to know if it was safe to try the fritters. The misconception that lionfish are poisonous is a large problem facing the management of the invasion, as it reduces the demand for lionfish!

After educating people that lionfish were in fact venomous (therefore the meat contained no toxins) and extremely tasty, the fritters were a hit!  Earrings made from lionfish fins were also on show, enabling us to increase awareness surrounding the lionfish jewellery market, another great way to increase incentive for the removal of the invaders from reefs. The team will be continuing to attend events like these in the future, passing on knowledge and changing people’s opinions on lionfish.

Record sized lionfish captured in Eleuthera

The Slayer Campaign has been a huge success at the Cape Eleuthera Institute this year, and we're well on our way to setting a new record for the total catch this season. The initiative provides the perfect opportunity for local fishermen, while also removing invasive lionfish from the reefs. Here at CEI we always make sure the fillets are passed on to our kitchen staff so that the taste can be shared throughout the community. Record 44 cm lionfish

The true spearing skills of our local fishermen were recently highlighted by the size of one lionfish in particular, whose total length reached a rather impressive 44 cm. You may remember we recently set an official record here at the Cape Eleuthera Institute with a 42 cm fish. So, when this new record breaker was laid before us on the dissection table, we decided to submit the numbers (and photo to prove it!) to the wider international community of fellow lionfish slayers. We can now proudly announce that our own 44 cm lionfish is the new official record for the whole Bahamas. Great work Dennis Johnson and Leonardo Butler for slaying this fish!

If you're curious, the world record is currently held at 47.7 cm, so we're not too far behind! Check out the Lionfish.co website for more details.

Graduate student update: Matthew Smith

Matthew Smith is a Master’s student of the Ecology and Environment Lab from the University of Exeter in the UK. The main focus of his study is the effects of anthropogenic noise on reef fish populations, vocalisations and behaviour. There have been many studies on the effects of anthropogenic noise on marine mammals, but substantially fewer studies have be conducted concerning how noise pollution is affecting reef fish. Hearing and vocalisations are very important to many species found in the patch reefs such as those off of the coast of Cape Eleuthera. Boat traffic is an emerging threat that is often forgotten when assessing the threats to marine populations. The team out on the boat, simulating acoustic pollution near experimental reefs

The primary study has involved selecting pairs of patch reefs with similar characteristics before splitting the pair into either treatment group, to receive increased or reduced boat traffic. By conducting fish surveys at regular intervals and recording using a hydrophone, Matthew is able to decipher if the changing levels of boat traffic is having an effect on the community living on each patch reef.

A secondary study is looking at the effect of boat traffic on damselfish (Stegastes spp.). Damselfish aggressively defend territories within which they preen a ‘garden’ of algae and have a heavy influence on algae populations on reefs as well as the behavior of fish in and around their territories. Using reefs that are less frequently exposed to boats, cameras are set up in front of damselfish territories to record how exposure to boat traffic affects their behavior. The end goal is to be contribute towards a better assessment of how anthropogenic noise pollution is affecting fish populations.
