The last couple years have cemented the shrinking coho concept for me. Closer to Seattle, the mature coho I am catching are averaging 1-3 lbs. They're so small that the look like they'd pass right through 4 1/2" mesh. Could this be mother nature's way of defeating gill nets? Is it possible that these smaller fish are the specimens that can consistently pass through the gauntlet of gill nets in the duwamish and lake union??

It would sure make an interesting study!
