Do you think that Skamania strain summerruns have a higher succes rate of spawning in the wild than our chambers creek winter strain?

I was asking this because ive notticed that Ive been getting more and more unmarked summerruns every year. Theese fish are perfect and clearly not raised in a hatchery environment.

In one of the rivers I fish you can really tell the difference in body shape between the wild and hatchery fish and a good number of theese unmarked fish resemble the Skamania strain more than actual the wild fish.

Somthin else I see is that the hatchery summerruns tend to stray much further than the hatchery winter fish.
