Should lionfish be culled in the Caribbean? in Conservation and the Environment Posted April 28, 2010 Maybe the spearfishers could satisfy their bloodlust (hunting tradition) by shooting tame Lionfish instead of tame Grouper? Could create awhole new sport and save the economy? Spearfishers in the Caribbean mostly shoot fish for food, and who would trade a grouper for a Lionfish? But as Bart says, even if we gave a spear to every diver in the Caribbean, eradication at this scale is virtually impossible. I am sorry to say that Lionfish is here to stay, the local fauna will just have to get used to it.
