It is illegal in Florida and for good reason I think. A guy just died about a year ago from a bite during a feeding in the Bahamas that was being run by an extremely experienced operator. If you talk to the people who engage in this work on a day to day basis, you will realize that it is not that safe and there are a number of accidents that probably don't get reported.
In addition it endangers sharks and spearfisherman when the sharks are habituated to this activity. Just because people make money off the activity, does not mean it is wise or justified.
I don't agree.
If there were a lot of accidents I feel pretty safe in saying that the media would be all over it. There are remarkable few accidents involving these feeds.
As for the diver who was bitten (and tragically died) in the Bahamas during a feed last year, according to witnesses, he broke the rules and got between the shark and the food. The shark was apparently clearly not trying to bite the diver. The shark was going after the food. The diver made an error.
Overall, I think shark feeds are safe and more importantly, positive because they raise awareness of how important sharks are to not merely the oceans, but the planet.
I have reported on shark feeds, and I have not only spoken with the people who feed sharks professionally, but I have spent a great deal of time with them. Everyone has a deep respect and abiding affection for these majestic animals. Safety is the paramount concern on the feeds.
As for spear fishing, I know professional spear fishers who say when they fish, the sharks come around --this happens in areas where there are no shark feeding operations so I don't see that as much of an issue.
Reasonable minds can disagree.
