What is ecologically correct, even helpful, to eat from the Atlantic Ocean – but not from the Pacific Ocean?
What in a well-made ceviche is rather firm and tastes like a cross between lobster and shrimp? What melts in your mouth, while the “butteriness” balances well with the lime juice”? And from the grill, what is a lot like grouper?
The answer is lionfish from the Atlantic Ocean and other areas where the introduced lionfish is destroying native marine life.
According to NOAA research, the very invasive lionfish found in the Atlantic Ocean prey upon numerous species of fish and crustaceans, such as juvenile spiny lobster, wrasses, parrotfish, blennies, and other ecologically important species. The Atlantic Ocean has very limited predators for lionfish, which inflict extremely painful venom from their spines.
Lionfish might have been introduced into Florida’s waters in 1992, when Hurricane Andrew capsized many transport boats and broke beach-side aquariums. It’s estimated that Americans alone import thousands of the stunning lionfish every year for their aquariums, and some later release the fish in no-native waters.
Reproducing year round, lionfish have no natural enemies and an extremely high reproductive rate of 2 million eggs a year from one female. Unsurprisingly they’ve taken over rapidly (NOAA).
A recent Oregon State University study found that in just five weeks, introduced lionfish reduced the native reef fishes by about 80 percent. The aggressive feeding of lionfish also reduces the numbers of herbivorous fishes that keep seaweeds and macro-algae from overgrowing corals. Lionfish are also taking over snapper and grouper habitats; they hamper stock rebuilding efforts and coral reef conservation measures. Voracious eaters, lionfish grow to a foot or more long, and their stomachs can expand up to 30 times their normal size!
Because native species in the Atlantic and other waters where the lionfish have been introduced do not recognize a lionfish as a predator, the local fish don’t flee. Lionfish can eat prey over half the size of their own body as long as it will fit into their mouths, and they eat almost anything.
The sharp spines of the lionfish contain a powerful venom: a single prick from a lionfish spine can cause days of swelling, discomfort and even paralysis. Pacific Ocean native fish know the danger, and stay away from lionfish (Smithsonian).
In the Western Atlantic Ocean, Caribbean Sea, and in the Gulf of Mexico, however, where lionfish are not native and have very few predators, environmentalists are fighting the lionfish invasion with traps, nets and spears, lionfish catching contests, recipes and cooking contests, including Bermuda’s Eat ‘Em to Beat ‘Em , campaign. Honduras divers are trying to train sharks to eat lionfish (National Geographic).
Atlantic Ocean lionfish are now being listed as the “ultimate in guilt-free eating – delicious, nutritious and eco-conscious. “ Chefs do need to know how to cut out the poisonous spines and prepare the lionfish correctly so as not to pass on the toxins to their guests. And the fishermen need to know how to catch them without being stung.
The next time you are in Florida, you might find lionfish on the menu. It’s not cheap: in Nassau, the capital city of the Bahamas, the August Moon Restaurant and Café has been serving lionfish since 2007. Alexandra Maillis Lynch, the owner and chef, serves lionfish tempura once every two months, whenever she can convince fishermen to supply it to her. She offers fifteen to twenty dollars a pound for the exotic specialty, nearly twice as much as she pays for the more common grouper (Smithsonian).
According to Southern Living magazine article “Eat the Enemy and Enjoy Lionfish this Summer,” “For chefs, the lionfish’s canvas-like versatility is a key strength. It’s difficult to imagine a preparation—from beer-battered, to sashimi, to vegetable-packed kebabs—that wouldn’t work.”
The story of the Atlantic Ocean lionfish is a good reminder to all of us that introducing alien species into any habitat can quickly lead to catastrophe, both for wildlife and for us.
Remember, our Pacific Ocean lionfish are part of the diversity of our waters – and they should NOT be eaten.
But consuming the Atlantic Ocean lionfish means you are helping the native fish and the commercial fishermen!
