In B.C. the fed fisheries fear the aboriginals and I suspect it would be the same in any other province with any particular natural resource. They don't consider it their job to protect natural resources or the environment. And also fwiw, in B.C. the fed fisheries officers are toothless when it comes to pursuing fines or jail time in most cases.
We will need to deal with this problem some day if it doesn't just naturally go away with time, as they are hoping it will.
