Lead Thrower:

In fact they do manage their hatcheries diffrently than we do, but I wasn't talking about that. I was simply saying they stuff badly degraded, urban rivers with hatchery fish and leave the others alone.

While I am by no means an expert on B.C. hatchery practices, I know they use rod and reel caught wild streelhead for most of their broodstock and that they hold them for up to four months until they are ripe for spawning.
The Vedder, which is about the size of the Nisqually gets 10,000 steelhead returning in a good year. They get 40,000 fall chinook.
