I have been on several shark feeding dives (usually live aboards). The first time was cool. I was a brand new diver had never been around or seen sharks, but have always been fascinated by them. After the first time, the rest of the feedings I have been on, I really could have cared less if it was done, but understand for those other new divers who want to see the experience. I much more prefer to see the sharks anymore, doing their natural behaviors. Are the feedings a good thing? I don't know... I see both sides. 1- it conditions the sharks to being fed by humans, reducing their natural fear of humans. 2- the sharks are not doing their natural thing. On the other side, I can see where it may be a bit of an educational thing for some divers who might not get any other chance to see sharks while diving. While yes, some of their behavior is not natural, some of it is, also. If anything, I look at it as a necessary evil (for lack of a better term), kind of like zoological parks & such.
