Feeding the Local Animals In the Park

Everyone must have been to the park to feed the ducks at some point in their lives and a lot of people feed the birds, what about feeding the fish in the local park. What about hand feeding the fish in the local park, what about feeding monstrous big fish that jump out of the water to grab whatever you had in your hand, i would be very worried about that but Tarpon are a very large fish that can jump out of the water to catch prey and at some fancy restaurants they actively encourage you to feed the large Tarpon, here is a very interesting pic i found on the net, i would be a bit scared about doing that.
