Fish Slayer, there is no money or desire from DFO to enhance this stock and IMO, that's a good thing. This particular hatchery stock of chinooks is a combination of interior river fish (Bowron, Finn, Chilko, Slim Creek, perhaps more). This broodstock was and still is genetically adapted to swim the Fraser up to 500km, find their home stream, spawn, incubate eggs at very low temperatures, then rear in the natal stream or main stem Fraser for up to 2 years.
The problem here on the C is these fish spawn around the end of August in a climate and water that has a totally different temperature profile than the fish are adapted to. Because of warm summer and early fall river temperatures, temperature units (the measurement that determines hatching rates), accumulate quickly. When these alevins emerge from the gravel in the early, early spring, water temperatures are down and food is scarce. The possibly/probably extinct indigenous red chinook population historically spawned about a month later, and through many generations, adapted to this environment.
This pool closure is to ensure what salmon do make it this far are afforded the protection and respect they deserve. And yes, it is about angler ethics. This closure and my post would not be necessary if that respect had been shown previously.
