If the O/P was discussing a snagger fishing on the Reserve then good for their success. They truly do need those fish and with the weather, and limited return they are having it hard enough. If it was anywhere else on the river the report it to the DFO immediatley. That being said, I think a few people need to brush up on their history
I doubt the Feds would have built such a nice hatchery as the Capilano or continued to fund it for all these decades if it wasn't for the drinking water dam destroying the salmon runs that the Squamish Band relied on in the '60s. Sporties don't have the political or judicial pull First Nations have, so we likely owe them for the hatchery-supported fishery.
First Nations did not even get the right to vote until 1960. Their political clout during the design and construction of many of the hatcheries in BC was minimal at best. Granted things have changed, and for the better in most circumstances, but not until the late 80's, with no real change until the 1990s. As for Natives not causing as much destruction as "white people," that is simple because they didn't have the resources or the ability. Take the current First Nation sockeye opening. The bands at the mouth are slaying them, but the Band I know around Fort Langley are getting very little. If you move further upstream the Bands are getting even less. There is no regard for others, or how many make it to spawn, just everyone taking as much as they can for themselves. Just like the "white people" mentioned in an earlier post, and pretty much every other group out there. It is human nature, and no one is above it.
