[Coral-List] Shark Feeding Question

Dear all, Not long ago, I got crucified in this list for showing a video where I was interacting and (oh the horror) touching a Goliath Grouper. In the upheaval, I didn't get the chance to say that I had done a Jane Goodall on that grouper, meaning, I had spent several dives getting to know that particular grouper, not feeding her but slowly swimming by her side, hanging around grouper-style and earning her trust. Perhaps that's the lesson to learn here.
After years studying animal behavior in the wild, my personal take of feeding wild animals is that the wild is always at the loosing end. The purpose of feeding wildlife is no other than to put the animals at our service. We want to see the animals doing things, and since we don't have the patience of Jane Goodall or Diane Fossey, we trick them with food to be here and now, so they fit our entertainment purpose.
Even the most well intentioned ecotourist is a predator, a benign one, but still a predator. You can predate old style (i.e. killing and eating a fish), or you can be subtle and set its behavior in disarray just enough to diminish long term fitness.
What kinds of behavior can we interfere with?1) pecking order, a sequence that determines who feeds first and who follows. This order could be well established, such as the alpha (dominant male and female) to the omega individual in the wolf, or it can be more fluid and ever changing as in marine species. The fish have already figured out who should eat first, but the humans don't know the correct feeding order. 2) feeding ecology: we don't always provide the correct food3) site attachment: by feeding regularly the fish, we condition them to associate divers with food at a specific time and place, which can conflict with their normal daily or seasonal movements.4) naivete: Billy Causey already illustrated the fate of the naive fish who no longer watch out for anglers or spearfishers
There are almost no research funds to spend time underwater and just look at the fish and see what they do, and understand why they do it. That's the good old field-based behavioral ecology. But the millions of dollars moving around fisheries, ecotourism, diving, etc, they all depend on truly knowing animal behavior.
