From the article:
"But Quinsam Hatchery manager Laurent Frisson stresses that the new program is not just for the Tyee Club, it is strictly to get to the roots of what type of chinook can best replenish the Campbell stocks.
“It’s not about that at all, we’re trying to determine the heritability from parents to offsprings and the size thing is just one thing to look at,” he said. “The reason we’re doing it is we want to find out what they inherit from whom, do they inherit it from the female or from the male, does it even happen? You look at the Campbell system and the way the Campbell system is; we’re trying to produce a fish that can thrive in the Campbell and that ain’t no small fish.
“If you look at it naturally, the smaller adults would not be able to dig appropriate redds, and nature would take care of it. We’re not trying to produce fish for a particular club or a particular group.”
And, yes, the small, short, little Campbell is such, with heavy water flows, in-river habitat and larger spawning redd gravel, that it favours larger fish."
