Fishbadger:

Interesting info...thanks for sharing and making it understandable for us non-scientist types.

Q: Based on your comments (regarding the genetics of non-native to that particular system broodstock) then is there any scientific reasoning why the state hatcheries broodstock from a different source for other rivers? (IE: Skamania broodstock for Skagit hatchery fish?)

Based on my understanding of your comments, we would be much better off spawning native fish from that particular river system for the hatchery fish on that system. Then, if any did return to spawn naturally, there is much less chance of genetic degradation since that returning hatchery fish was spawned from another of the same system.

Does that make sense? If so, the why don't the hatcheries take their broodstock right from the river they are planting?
