Mr. Chen, No, no feeding on those dives, and in fact I liked Randy personally, I liked the layout of his boat and his general operation. Thanks to You Tube, however, I, like the rest of the world, have seen enough of the shark feeding to pass judgment on it. I have no criticism of Randy except for the way they conduct these shark feeds. Unfortunately, it seems to have become his main draw, main money maker and main source of publicity. He does, I am sure, a thriving trade with macho divers seeking the best You Tube or photos in dangerous situations for bragging rights.
I am not surprised that it is affecting shark behavior at other sites. I have seen lots of posts here about there being more, and more aggressive, sharks at other regular sites that did not used to have them. A year ago, sharks would stand off at places like Tunnels and Shark Canyon. You would see them, but at a distance and they were not interested in approach. In other words, behaving normally. Now, close approach is common and apparently the approaches can be fast and threatening. This coincides with the rising frequency of these shark feeds, which, it now seems, are being conducted closer to shore than they were saying. Might be coincidence, true, but I doubt it.
