Fighting the Lionfish Invasion: Cayman’s Success Story


Lionfish: A striking yet invasive species

The beautiful waters of the Cayman Islands are home to an incredible array of marine life. However, a new resident is causing significant disruption to the coral reefs and fragile ecosystems. The Lionfish is an invasive species that has been steadily creeping into the Caribbean for years, but the Cayman Islands is taking action to stop its spread and protect its reefs.

What are Lionfish, and why are they a threat?

Lionfish (Pterois) are beautiful but venomous, predatory fish native to the Indo-Pacific region. They were first introduced to the Caribbean in the early 1990s, most likely by releasing aquarium specimens into waters off Florida. Since then, they have spread throughout the Caribbean Sea and the Gulf of Mexico, where they have few natural predators and abundant food sources. Lionfish populations have exploded in recent years and are now considered invasive in many areas.

Due to their voracious appetites for small fish and invertebrates, Lionfish pose a severe threat to native marine ecosystems. The species can consume twice its body weight in a single day and has been known to reduce native fish populations drastically. The rate at which they can reproduce is also alarming.

Education and Awareness Initiatives

But there is good news: the Cayman Islands is fighting back against the Lionfish invasion and winning the battle. Cayman is one of several countries working to control the spread of Lionfish through various management strategies. These include public awareness campaigns and Lionfish derbies (where people compete to see who can catch the most Lionfish). Additionlly educational programs teach people how to handle and cook these fish safely. While it is challenging to control these invasive predators, the Cayman Islands is committed to preserving its marine ecosystem for future generations.

Lionfish as Food

Jason Washington, master diver, photographer, and environmental activist, has led the way in championing the ‘Lionfish as Food’ campaign and is the driving force behind its success. The first “lionfish rodeo” was held in 2010. Local chef Thomas Tennant participated and helped to turn the Lionfish into a local delicacy. Their efforts have been instrumental in raising public awareness of the dangers posed by Lionfish and how they can be managed through their removal from the environment.

Since then, Caribbean fishermen, divers, local restaurants, and chefs such as Eric Rippert have collectively joined forces and formed a movement dubbed by Michelin-starred chef José Andrés “Eat ‘Em To Beat ‘Em.”

The “Eat ‘Em To Beat ‘Em” campaign has successfully encouraged people to eat Lionfish to help reduce their numbers. The campaign successfully got restaurants on board, with many now offering Lionfish dishes on their menus.

The Lionfish is a delicious and versatile fish that can be prepared in many ways. It can be fried, grilled, steamed, or raw as sashimi. The flesh has a delicate flavour that pairs well with bold sauces and spices, making it a popular choice for chefs looking to create something unique. So next time you’re looking for something different to order at a restaurant, why not try some tasty Lionfish?

The Cayman United Lionfish League, known as CULL

The Cayman United Lionfish League, or CULL, is a local non-profit organisation founded in 2011 following the first “Lionfish Rodeo” success. Their mission is to continue efforts to control the lionfish population in the Cayman Islands. Through education, awareness, and removal programmes aimed at seeing this invasive fish off the reef and onto people’s plates.

CULL works with partners like the Department of Environment and Marine Affairs to organise regular Lionfish derbies. During these derbies, divers compete to catch the most Lionfish. The derbies are open to anyone who is an experienced and certified diver, and prizes are awarded to the team that captures the most Lionfish.

Healthy Cayman Reefs

The Cayman Islands is a shining example of how communities can come together to combat invasive species and protect the environment. Through education, awareness, and coordinated efforts, the Lionfish population in the Cayman Islands is slowly but surely being controlled. The steps to remove Lionfish from these waters will ensure that the Cayman Islands remain a vibrant and thriving ecosystem for future generations.
