I just saw a report on the news about a population boom of lionfish in the Florida Keys. They didn't say what kind of lion but they looked like volitans. They're blaming hobbyists that have released their pets into the ocean. Lionfish don't really have any predators after them because of their venom but they can prey on a wide variety of fish and inverts. For this reason there is worry about their impact on the ecosystem. They have been trying to collect and kill them by hand. They also said they are trying to make them more of a food fish which surprized me the most. This is just what I saw in a quick report. If anyone has any input or more information about this I'd like to hear it.
