Fishing is highly...and I do mean highly regulated in Montana (spawning grounds). http://fieldguide.mt.gov/speciesDetail.aspx?elcode=AFCAB0101... There are wildlife biologists that harvest the eggs and process the meat for you. You must apply for tags and the season can be shutdown if a limit is reached before the end of the season. I fished it once and was glad I didn't catch anything. My heart wasn't in it after I saw the first one caught. They reminded me too much of dolphins and they have to be snagged. They do not take bait so the fish...imo is not brought in as quickly and humanely as I was comfortable with. We hunted and fished because without it quality protein was scarce during my childhood. It was a creature I just chose to appreciate and eat more mac and cheese.
