Floridians hunt invasive lionfish

The one thing I worry about with people eating them is the possibility that demand could spawn fisheries where they are bred for meat, and if I recall, fisheries are often adjacent to natural sources of water (I suppose salt water, such as the ocean, would be require) and there could be escapees. However I’m not too keen on saltwater fisheries, I’m not sure I’ve ever actually heard of them being a thing. It’s possible that my fears are completely unfounded as the concept is impossible, please, someone tell me its not possible.
