Another "it depends" situation. On my home waters, the Bow river, if a fish is put down from feeding, it could take an hour or more before it gets back to feeding. On another river in Montana, a fish that has been put down often comes back to the feeding station/behavior in about 10 minutes. The solution is to put lots of time in on a piece of water and figure out the fish in there. Once you have figured out fish behavior, keep it a secret because it is probably worth several millions in a book deal or something.
