Yes, Lionfish are an exception and we kill them as we dive. It's against a lot of good rules to spearfish with a tank on your back but Lionfish spearing is a new industry and very popular here.I keep a dozen or so special Lionfish spears in the dive shop and hand them out to those interested. Having said that the divemaster is boss and we'll always consult with him.We also clean and eat them. We have a chef at Las Terrazas that loves to serve them.
