The white sand beaches and emerald green waters of Destin, Florida are the setting for the ""World's Luckiest Fishing Villages."" Beneath the water's surface, it's a different story...one of the most formidable species, the lionfish, has been wreaking havoc on the local ecosystem for decades. The ecological advantage of the lionfish is its venomous spikes, used to corner prey and protect itself from predators, and giving it an advantage over native fish. Luckily, local conservationists and fishing captains discovered years ago that lionfish are as tasty as they are dangerous. Yia joins local biologist Alex Fogg as he works to mitigate the lionfish's damage by harvesting them one buttery, flaky bite at a time.
