While some designated trout streams mandate the use of artificial lures or flies only, many stocked streams permit the use of various forms of natural bait. Obviously, before fishing any body of water, it is a good idea to carefully scrutinize the regulations pertaining to that location. If it is permissible to use live bait, then the selection is almost endless. After feeding on fish pellets for nearly a year, newly stocked trout have two options: switch to natural foods or starve to death. A week or two after stocking, most trout will eat just about anything that comes along, especially if it looks perfectly natural.
