Rum - Lionfish are kinda the scourge of the reef. Starting about 2 years ago for some reason tons of them came and "invaded" Jamaican waters. There's been a real push for fishermen to catch them - when cleaned properly they are apparently a nice tasting fish, many restaurants have them on the menu. The fact that you saw just a few is a testament to the fishermen pulling them out and the community using them for food. In Alligator Pond at a restaurant called Little Ochi they were going to be having a a lionfish cook-off competition!
