Description<\/strong><\/p>\n\n\n\n

This fish, native to the Indo-Pacific region, arrived in 1992 after a Florida aquarium was destroyed during Hurricane Andrew. Since then, it has become highly invasive, with its population growing rapidly. Females can lay up to 30,000 eggs every 4 days\u2014approximately 2.5 million eggs per year.<\/p>\n\n\n\n

Additionally, its poisonous spines make it intimidating. These spines contain a neurotoxin that causes intense pain and can sometimes lead to temporary paralysis if stung.<\/p>\n\n\n\n

Habitat<\/strong><\/p>\n\n\n\n

The lionfish is a common scorpionfish that inhabits reefs of the Indian Ocean. It had never been seen in the Atlantic prior to its invasion in 1992.<\/p>\n\n\n\n

Why is it invasive?<\/strong><\/p>\n\n\n\n

It has almost no natural predators in the region. Meanwhile, it is a highly effective and aggressive predator itself, capable of consuming around 20 fish in 30 minutes. It feeds on a wide variety of fish, crabs, shrimp, and octopuses, posing a major threat to biodiversity.<\/p>\n\n\n\n

Even though it does not eat corals directly, it preys on herbivorous fish that clean reefs, indirectly damaging many coral ecosystems.<\/p>\n\n\n\n

The invasion first reached the Bahamas, but today the entire Greater Caribbean region is at risk: Bermuda, the Cayman Islands, Cuba, Jamaica, the Dominican Republic, Puerto Rico, Honduras, Costa Rica, Haiti, the Virgin Islands, Belize, and Panama.<\/p>\n\n\n\n

Control and eradication<\/strong><\/p>\n\n\n\n

Efforts are underway to reduce its impact. In Honduras, a program teaches fishermen and locals to hunt lionfish with spears.<\/p>\n\n\n\n

Scientists are also training carnivorous predators\u2014such as groupers, reef sharks, and moray eels\u2014to eat lionfish by feeding them lionfish directly.<\/p>\n\n\n\n

Another approach is to encourage humans to eat lionfish. Despite its venomous spines and bad reputation, it is edible. In Guadeloupe and Martinique, some chefs have already turned it into a gastronomic dish.<\/p>\n\n\n\n
