by The Caye Caulker Lionfish Derby is Belize's most spirited marine conservation event, where divers, spearfishers, and local chefs compete to remove invasive lionfish from the reef. Held off the island of Caye Caulker, the derby pairs an adrenaline-fueled underwater hunt with a lively cook-off, proving that eating a problem fish can help save the Belize Barrier Reef.
Key Takeaways
- The Caye Caulker Lionfish Derby is a competitive culling event that removes invasive lionfish to protect the Belize Barrier Reef.
- Lionfish are an Indo-Pacific species with no natural predators in the Caribbean, breeding fast and preying on native reef fish.
- Past Caye Caulker derbies have removed hundreds to nearly a thousand lionfish in a single day.
- Lionfish are safe to eat once the venomous spines are removed, so the derby doubles as a sustainable-seafood festival.
- The event welcomes divers, foodies, and conservation fans, making it one of the most accessible reef-protection experiences in Belize.
What Is the Caye Caulker Lionfish Derby?
The derby is a timed tournament in which teams of divers and spearfishers race to catch as many invasive lionfish as possible in a single day. Unlike ordinary fishing contests, there is no catch limit here: every lionfish pulled from the water helps the reef recover.
The first Caye Caulker Lionfish Derby launched in 2016, and it quickly became an annual fixture on the island. According to The San Pedro Sun, the second edition removed close to 1,000 lionfish, and later tournaments have continued pulling hundreds of fish from Belizean waters each year.
Caye Caulker sits along the Mesoamerican Reef, so the island is the perfect base for this kind of hands-on conservation. Caye Caulker is a dream destination for divers, and the derby turns that world-class diving into direct reef protection.
Why Are Lionfish a Problem for the Belize Barrier Reef?
Lionfish (*Pterois volitans* and *Pterois miles*) are native to the Indo-Pacific and Red Sea. They entered Atlantic and Caribbean waters through the aquarium trade, and with almost no natural predators in the region, their numbers have exploded.
They Devastate Native Fish Populations
Lionfish are indiscriminate predators that swallow almost anything small enough to fit in their mouths, including juvenile snapper and grouper. NOAA Fisheries reports that a single lionfish on a reef can reduce native reef-fish recruitment by up to 79 percent.
They Damage the Reef Itself
Healthy reefs rely on herbivorous fish to keep algae in check. When lionfish eat those herbivores, algae can overgrow the coral, degrading the reef that Belize's tourism and fishing economies depend on.
They Breed Extraordinarily Fast
Mature female lionfish can release around 50,000 eggs roughly every three days year-round, according to NOAA's Flower Garden Banks National Marine Sanctuary. Traditional line fishing barely dents that growth, which is exactly why organized culling events like the derby matter.
| Lionfish Fact | Detail |
|---|---|
| Native range | Indo-Pacific and Red Sea |
| How it arrived | Aquarium trade release |
| Reproduction | ~50,000 eggs about every 3 days |
| Reef fish recruitment impact | Up to 79% reduction (per fish) |
| Venomous spines | 18 across dorsal, pelvic, and anal fins |
| Natural Caribbean predators | Effectively none |
How Does the Lionfish Derby Work?
Here is how a typical derby unfolds.
Registration and Safety Briefing
Participants form small teams and register in advance. Organizers cover safe spearfishing technique and, crucially, how to handle lionfish without getting stung by their 18 venomous spines.
The Hunt
At first light, teams head to the reef with pole spears, Hawaiian slings, and containment tubes. They target lionfish across shallow reefs, deep reefs, and mangrove edges. The more fish removed, the better the score and the better the reef.
Weigh-In and Judging
After several hours underwater, teams return to Caye Caulker for the official count. Judges typically award prizes in categories such as:
- Most lionfish caught by a team
- Largest lionfish
- Smallest lionfish
- Best lionfish dish prepared by a chef
Cook-Off and Celebration
The day ends with a community cookout. Local chefs turn the catch into ceviche, tacos, grilled fillets, and even sushi rolls, backed by music, dancing, and educational booths.
Can You Really Eat Lionfish?
Yes, and it is one of the best reasons to attend. Once the venomous spines are trimmed away, lionfish flesh is white, flaky, and mild, comparable to snapper or grouper. The venom is in the spines, not the meat, so a properly cleaned fillet is completely safe.
Popular derby preparations include:
- Lionfish ceviche cured in lime and served with tortilla chips
- Grilled lionfish with garlic butter
- Lionfish tacos with fresh island slaw
- Lionfish sushi rolls
By putting lionfish on menus, the derby builds real market demand. That takes pressure off overfished native species and gives Belizean fishers a new income stream.
Why Does the Derby Matter for Belize?
Reef Conservation
Every derby directly reduces the lionfish population on the Belize Barrier Reef, part of the wider Mesoamerican Reef system that shelters countless native species.
Tourism and Local Economy
The event draws divers, marine biologists, and curious travelers to the island. Hotels, restaurants, and tour operators all see a lift, reinforcing why Scuba Diving & Snorkeling in Belize remains a cornerstone of the local economy.
Education and Community
Booths, demonstrations, and the cook-off teach visitors how invasive species work and how everyday choices, like ordering lionfish, support the reef.
How Can You Take Part?
- Gear up: Bring or rent pole spears and puncture-resistant gloves; coolers keep the catch fresh.
- Train first: Local dive shops offer lionfish-handling clinics before derby day.
- Cull responsibly: Target only lionfish and avoid contact with living coral.
- Not a diver? Judge the cook-off, sample the food, or simply cheer the teams at weigh-in.
Frequently Asked Questions
When is the Caye Caulker Lionfish Derby held?

Yes. The venom is confined to the spines, which are removed during cleaning. The fillets are safe, mild, and delicious.
How many lionfish are removed at the derby?
Past Caye Caulker derbies have removed hundreds of lionfish in a day, with one early edition approaching 1,000 fish.
Where is Caye Caulker?
Caye Caulker is a small island off mainland Belize, sitting alongside the Belize Barrier Reef within easy reach of Belize City and Ambergris Caye.
Conclusion
The Caye Caulker Lionfish Derby shows how tourism, food, and conservation can pull in the same direction. By spearing invasive lionfish, filling menus with sustainable seafood, and teaching visitors about reef health, the event protects one of the world's great marine treasures while giving travelers an unforgettable island experience.
