A guy I worked with for years was an avid fisherman. He always claimed if you used the right gear in the right place in the proper manner you can get a Steelhead to bite, all about knowledge and skill. Salmon the same applies but if you could get one out of a hundred to bite as they swam by you were lucky. Next guy the same up stream but salmon once out of the salt their behavior is all over the place. Thing is if you fish a hatchery run for many generations with pole you will steadily remove fish from the run that inclined to be aggressive when in fresh water. I read someplace that they were going to add wild fish to an eggtake to try to counteract this.
