At Mexican cave site of the coral reef off the coast of Ambergris Caye. This fish, Pterois volitans is an invader in the coral reef ecosystem off the coast of Belize with no predators. Its increasing population is a real danger for the sustainability of the coral reef. For that reason, lionfish is speared by guides and fishermen with the hope that some native fish will develop a taste for its flesh and thus keep its population under control.
"Pterois volitans and Pterois miles are native to sub-tropical and tropical regions from southern Japan and southern Korea to the east coast of Australia, Indonesia, Micronesia, French Polynesia and in the South Pacific Ocean. Adult lionfish specimens are now found along the United States East Coast from Cape Hatteras, North Carolina, to Florida, and in Bermuda, the Bahamas, and throughout the Caribbean, including the Turks and Caicos, Haiti, Cuba, Dominican Republic, Cayman Islands, Aruba, Curacao, Bonaire, Puerto Rico, St. Croix, Belize, Honduras and Mexico. Population densities continue to increase in the invaded areas, resulting in a population boom of up to 700% in some areas between 2004 and 2008. Population densities have reached levels that are orders of magnitude greater than their native ranges. Pterois volitans comprises the largest part of the invasive lionfish population in the Atlantic and Caribbean." (Wikipedia)
