I saw this recently on Civil Eats – Florida’s Answer to Invasive Lionfish? If You Can’t Beat ‘Em, Eat ‘Em: https://civileats.com/2019/01/02/floridians-answer-to-invasive-lionfish-if-you-cant-beat-em-eat-em/. Longer article. Seems to be a good fish to eat from the article.

While it’s possible to catch a lionfish with a rod and reel, the name of the game on derby day is speed, and most teams use spear-fishing techniques in order to catch as many fish as possible. During the most recent derby, which took place in the waters around Key Largo from sunup to sundown over three days last September, 14 teams competed for the chance to win $1,000.
In areas where lionfish numbers are high, Green has found the density of native species reduced by up to 90 percent—and many of these native species play vital roles in the reef ecosystem. For instance, lionfish are known to prey on juvenile parrot fish, which would otherwise grow up to eat algae off of coral, allowing the coral to thrive. Lionfish also eat other species that are ecologically important as cleaners that remove parasites from other fish. Lionfish have affected grouper and snapper populations, too, which are already imperiled from overfishing.
