The goal of this project is to determine if a commercial lionfish fishery is viable in the U.S. Virgin Islands. As an invasive species to the Caribbean, lionfish threaten many local reef fish populations and, thus, threaten the traditional supply of fresh, local seafood. A research team from Emory University, the University of Florida and Georgia Southern University investigated the potential for the development of a market for fresh, local lionfish and a sustainable commercial lionfish fishery in the USVI. The study used information gathered from fishermen, consumers (locals and tourists), and retailers during the summer of 2016.

This document summarizes key information from the study, including where lionfish are harvested and sold, how to fillet lionfish, how to best promote lionfish sales, and safety information.

LIONFISH ANATOMY

Maps 1 and 2 on the following pages show the familiar landmarks and ocean habitats important for fishermen that are around St. Croix (Map 1) and St. Thomas and St. John (Map 2). Since different fish like different habitats, this may be useful in deciding where to fish. The maps show common dive sites ( ) and boating ramps ( ).

Lionfish have 18 venomous spines, but there is no venom in the meat, and they are NOT poisonous. The smaller the lionfish, the sharper the spines.

To be certain you do not get poked by a spine, you can use scissors to cut the spines off before filleting them. You can also fillet a lionfish without cutting the spines, just be careful! Puncture resistant gloves are recommended. See pages 11-12 for filleting instructions.

Use protective gloves, and note the location of the venomous spines (marked in yellow below).

FILLETING LIONFISHSTEP 1:

Holding the pectoral fins up and away from your body, make a shallow cut (around 3 cm deep) just behind the

cheek, then cut down the belly.

STEP 2:

Make a shallow (about 3 cm deep) cut along the spine connecting with the previous cut along the cheek.

STEP 3:

NOTE: Cut locations marked in red.

Peel skin from the cut section.

STEP 4:

Going back over the previous cuts, cut parallel to the body going deeper each time. Continue until the flesh is

completely removed. Repeat process on other side of page.

STEP 5:

Lionfish are invasive, and they cost you money because they eat the local fish that you like to catch.

But by eating and selling lionfish, you can keep their numbers low and protect the other reef fish that lionfish feed on.

Since these lionfish are not native to local reefs, there are no restrictions on harvesting them.

SELLING LIONFISH

Lionfish are healthy for you to eat! They are high in Omega 3s, low in saturated fat, and low in mercury levels.

They taste great too! They are a flakey, white fish and taste like red porgy, or a combination of grouper and mahi-mahi. They are not “fishy” and have a firm texture.

Aside from the taste and health benefits, by eating locally caught lionfish, you are getting fresh fish.

Eating lionfish promotes food security on the islands.

Lionfish are invasive to USVI and are an aggressive, top-predator fish that can reduce the population of other valuable reef fish by about 80% in just 5 weeks! So eating lionfish is environmentally friendly.

Lionfish are safe to eat and environmentally friendly. You are no more likely to get sick from lionfish than you are from another species that eats other fish, like grouper!

Cooking them whole neutralizes the venom, but they can also be filleted and prepared like any other reef fish.

Look for the orange and white “Eat the Enemy” logo to help protect our reefs.

WHAT SHOULD I TELL MY CUSTOMERS ABOUT LIONFISH?

St. Croix has a number of food markets that are likely to buy lionfish from fishermen, which are identified on Map 5. The survey was also able to show where residents who are most likely to try lionfish are located (see Map 6). Map 7 shows restaurants that indicated interest in buying lionfish from local fishermen to sell, and they are listed on page 25.

higher the interest. There were no survey responses in green areas. This may be useful in planning where to sell lionfish.

Other restaurants may also be interested in buying lionfish, but did not want to be formally listed in this publication.

PREPARING LIONFISH TO EATLionfish can be cooked and consumed in a wide variety of ways, just like grouper, snapper, porgy, or any other reef fish.

Lionfish can be grilled, boiled, fried, baked, or made into ceviche or tacos ... Just to name a few of our favorites!

The spines can be removed, or the fish can be cooked whole and the heat from cooking will nuetralize the venom inside the spines. See page 11-12 for how to fillet a lionfish and avoid being stung.

Filleting a lionfish is similar to filleting any other fish, just watch out not to poke yourself!

Ciguatoxic fish poisoning (CFP) causes people to get sick when they eat fish that has eaten a certain type of natural toxin - one from plankton that grows in warm waters and is transmitted up the food chain - or by eating other fish that are infected. The toxin gets stored in the fat of fish, and the highest levels are found in predatory fish. Cooking fish does not kill ciguatera because the toxin is not destroyed by heat.

Since the cause relates to contaminated waters, it’s not specific to any one kind of fish. When someone gets sick from ciguatera, it’s because of where the fish was caught, not what kind of fish it is. Maps 8 and 9 show ciguatera presence reported in USVI.

Symptoms of CFP can begin to occur within 6 hours of consumption and include nausea, vomiting, diarrhea, weakness, tingling, and a reversed sense of hot and cold.

If you suspect CFP, seek medical attention.

You are no more likely to get sick from lionfish than any other top-predator reef species!

UNDERSTANDING CIGUATERA

Only 13% of 421 consumers (tourists and locals throughout St. Croix) who were surveyed during the summer of 2016 had ever eaten lionfish. Of those who had eaten lionfish, 82% reported that it “tastes good.” And 81% of potential lionfish consumers are interested in trying new kinds of seafood.

Restaurants were estimated to be willing to pay fishermen $6.20/lb, on average, for whole lionfish from local fishermen. Local residents valued buying lionfish to cook at home at $10.09/lb and $17.70 for an entrée at a restaurant. Tourists are willing to pay 18% to 29% more than locals to buy lionfish to cook at home or for an entrée at a restaurant, respectively.

There is tremendous potential to educate the public to increase consumer demand for lionfish in USVI.

and avoid all areas where you believe ciguatera toxin may be present.

TREATMENT OF STINGSIf you are stung by a lionfish, do not panic. Lionfish stings are painful, but there are no recorded cases of them being deadly.

IF YOU ARE STUNG, FOLLOW THESE INSTRUCTIONS:

1. If stung while diving, signal to other divers that you've been stung and surface slowly. Surfacing too quickly can lead to decompression sickness, which is more dangerous than the lionfish sting, so surface safely.

2. Once surfaced, remove any stingers that may be stuck in your skin.

3. Rinsing the wound with warm (but not scalding) water for about 30 minutes, or putting a heat pack on it, will help neutralize the venom and prevent more from entering your bloodstream.

4. If you are able, consider taking an over-the-counter pain medication such as Benadryl® to help with the pain. Ask your doctor to determine what is right for you.

5. Monitor the sting area for dead skin or contin ued swelling. In the event that your throat begins to close, seek medical help immediately.
