While most reports of a precipitous decline in an animal population are met with dismay, ecologists are responding optimistically to news of decreased sightings of the lionfish in Jamaica.
With its vivid candy stripes and incredible fringed, flowing fins, the football-sized lionfish is a beautiful creature to behold; it is also a fast-growing voracious eater that reproduces year-round. And it has no known predators in the eastern Atlantic and Caribbean, where it has taken up residence since the early 2000s, presumably as the result of people releasing the popular aquarium fish into coastal waters.
Four years ago, Jamaica launched a campaign to decrease the population of lionfish in an effort to preserve regional reefs suffering from the species’ taste for native juvenile fish and crustaceans. Now Jamaica's National Environment and Planning Agency has revealed a 66 percent drop in sightings of lionfish in coastal waters with depths of 75 feet, reports ABC News.
Dayne Buddo, a marine ecologist who focuses on marine invaders at the Caribbean island's University of the West Indies, believes the decline is due to a changing attitude about the fish by local fisherman. Although those multiple flowing dorsal fins are exquisite to look at, they pack a powerful punch of venom, and Buddo said that in the past, Jamaican fishermen have been hesitant to deal with the pain-inducing fish. However, now the species has become a popular food item.
As it turns out, the spines are easily removed and cooking neutralizes the poison; plus, they taste good. The white flesh of the fish is said to be similar in flavor to certain snappers and groupers.
"After learning how to handle them, the fishermen have definitely been going after them harder, especially spear fishermen. I believe persons here have caught on to the whole idea of consuming them," said Buddo.
In regions where they have become a problem, governments, conservation groups and even dive shops have been holding fishing tournaments and other promotions to try to make a dent in the crisis. In 2010, the U.S. National Oceanic and Atmospheric Administration launched a campaign urging the public to "eat sustainable, eat lionfish!"
Generally we'd bemoan the idea of eating an animal population into oblivion, but for the lionfish, and other invasive species of its ilk, it may just be the most effective solution. Other dwindling species are spared the fate of the plate, ecosystems are preserved, and people still get to eat; in Jamaica, at least, this approach appears to be working.
More recently, lionfish has been on the menu in Florida, as the invasive species has posed a threat to the state's reefs. More than two dozen Whole Foods stores are offering shoppers the chance to purchase native lionfish for their dinner tables. Store staff will be specially trained to learn how to remove the poisonous spines.
"Once caught and placed on ice, the lionfish physically cannot release venom from the gland, ensuring safe consumption for shoppers," Whole Foods said in a release.
According to the Gulf Coast Lionfish Coalition, the fish can be prepared many ways: in chowder, sautéed, deep-fried, with lemon or lime in ceviche, panko breaded and fried or fried whole.
