I just checked the Aboriginal Fishery Notices and there is no closure for this group.
So I must assume that they are not breaking any laws IF they are from First Nations.
I understand your frustration but it's like saying it's not fair to drive a car when you're under age.
Spout and spit all you want, you still can't operate one legally.
If you have time on your hands, drop by the fisheries office in Port Alberni, and get the facts straight from them.
If you are then so inclined, contact your MP, MLA, etc. and complain to them.
Let me know how it goes.
