I think someone hasn't heard the fall chinook in the Chilliwack are not native and without hatchery support would likely disappear after a few generations. No need to worry about genetic quality of the brood stock
Is that why they only clip the adipose fin of cohos?  Other species they don't bother because they all came from the hatchery?

they also clip sockeye and fall chinook, but mainly for research.

the white chinooks have thrived since being transplanted from the harrison...they're an aggressive species that doesn't need to rely on the hatchery for survival... if not for fishermen targeting them, they would have decimated the indigenous populations (which now rely on the brood stock program for maintaining their numbers).

The red springs taken for brood stock are not indigenous as well (assuming you are talking about the July run). They are interior stock fish.

The actual indigenous population runs during steelhead season, which is why there are posters up everywhere showing the difference between steelhead and chinook. I have only ever seen 3 of these fish caught in the upper river. There was also a small run of the indigenous reds in the fall, I normally tag 1 or 2 every year that I fish the vedder. Seemed the last year before I left for college they were making a small comeback as I hit 5 that year that were reds, and were still chrome (some with sea lice) in late September.

O and clipped sockeye are solely to mark Cultus Lake hatchery enhanced sockeye. None are clipped for research that I know of, especially since the hatchery doesn't raise sockeye due to IHN outbreaks that they commonly have. They simply want to see if there is any actual wild representation left over.

I caught 4 red springs this fall season, and took one home. :)

correct...and as for the cultus lake sockeye doesn't that study and observation constitute ''research"? they also clip a selected number of chinooks.

ED
  The indigenous red springs enter the system in May, June and early July. They start spawning mid Sept to Mid October. Only a small number of these fish return each year and they all spawn in the upper
Chilliwack. Any fall reds that are being caught in the fall are not indigenous Chilliwack chinook and most likely Harrison chinook. The hatchery has noticed numerous red fleshed jacks and adults during brood stock spawning.
Attempts at capturing these fish for brood stock has been nearly impossible due to their spawning location and numbers.
Red springs are eggs taken from Slim Creek fish which is 100 miles N/E of prince George.

It seems like every thing pisses you off. Of your 300+ posts I'd be surprised if even one had some sort of positive tone to it. Lighten up and quit being a downer.
