Certain species have possibly been made extinct by spearfishing. The Brazilian rainbow parrotfish comes to mind. In the big picture of killing fish, spearfishing is a miniscule part of the destruction of fish by man. As we continue to raise unshirted h*** on fish populations worldwide, the few fish taken by spearfishing are insignificant. It's an anachronistic sport in a world where technology destroys huge fish populations relentlessly. An exception might be large grouper. I have been in no take areas in the Keys and it is remarkable what a reef looks like with its large groupers intact and not on someone's dinner plate. I think killing a grouper is like killing a dog and eating it. But I don't think it should be banned. Some people rely on it for their seafood. I don't agree with spearfishing, but we so casually surrender our personal liberties for really trivial reasons and it should be allowed.
