The Lionfish is warned for its toxic flesh
Local scientist in St. Maarten is warning the islanders not to eat lionfish after tests found a naturally occurring toxin in the flesh of the candy-striped invasive species. The findings have dealt a blow to the tiny Dutch territory’s efforts to contain the spread of the venomous predator, a native of the Indian and Pacific oceans that has colonized large swaths of the region after a few apparently escaped a Florida fish tank in 1992.

Following the lead of other Caribbean islands, St. Maarten had hoped to promote the species as batter-fried or grilled delectable’s to slow their spread. They were found in the Dutch territory’s waters in July 2010 and have been multiplying and gobbling up native fish and crustaceans ever since. Lionfish were first detected in the Bahamas in 2004 and rapidly spread south into the warm waters of the Caribbean. But Tadzio Bervoets, chief of St. Maarten’s Nature Foundation, said nearly half of the football-sized lionfish captured in local waters were found to have a bio toxin that can lead to ciguatera poisoning, a rarely fatal but growing menace that has long been known in the Caribbean, South Pacific, and warmer areas of the Indian Ocean. Ciguatera poisoning is caused by eating some subtropical and tropical fish predators, including grouper, snapper and barracuda, which live by reefs and accumulate toxins through their diet. They accumulate the toxin in their flesh from eating smaller fish that graze on poisonous algae.

People who have eaten infected fish can experience abdominal pain, nausea, vomiting, diarrhea, tingling and numbness. Most patients recover in a few days. In rare, worst cases there is paralysis and even death. No one has gotten sick from eating lionfish in St. Maarten, but the territory typically has more than a dozen cases of ciguatera poisoning each year from people eating barracuda and jacks. St. Maarten’s waters have long suffered from high levels of ciguatoxin, so Bervoets said the test results on lionfish were not a complete surprise.
