I have never run across natives (off of the reserve area) snagging fish on the cap...I have however seen lots of identifiable groups other than FN abusing the cap in a variety of spots.
Didnt 3 FN guys get busted breaking into the hatchery and netting some fish out of a holding tank...there are always going to be a few numb nutz out there but in general, I see more abuse from other groups.
While certain FN individuals may not always come across as stewards of the land, I think in general, there is a stronger connection and releranve for the environment with FN people than with other cultures that are known for plundering their natural environment.
Bottom line is that if FN are going to be taking fish for their community, the cap is a perfect place to do it: there is no wild run left, the fishery is maintained by a federal hatchery, the springs aren't even nature to the river (I've been told they are harrison stock), there is very little natural spawning grounds, the water is super cold and fluctuates wildly which greatly impacts what little spawing there is, etc, etc.
If I saw this on the seymour, or up either valley it would be a different story but thats not the case....
