Over the decades we remove them. What spawns is what survives. There are wild coho in PS that are now spawning in December/January and later. Why? because their parents did.

For a long time I scoffed at the the idea that hatcheries, especially, bred non-biters. Again, if you harvest 90% of the run, and much/most is with hook and line just what does live?

Basically, what spawns is what doesn't get caught.

(Un-) Natural selection at its finest.

Give that man a GOLD star.

This is why it's important that the big ones get away and we let a few go to keep the biter trait alive and well.

Maybe that's why we catch so many stinkin' tules in the lower Columbia?
