CC I find the lack of understanding of what drives the down sizing or alternation of salmonids to be just plain strange. From Chinook being blasted on the marine which is the reason of the loss of 5 and 6 yr class which means smaller fish dominate. Non biting Coho? Well if you hook and line out the aggressive ones long enough you will get a return that sticks to natures rules, no bite in fresh water. The most dramatic that was told me years ago was taking a 12 to 15 lb hatchery Coho brood and netting the hell out of it resulting in the smaller fish escape more and then eventually dominate the brood and wella a 5 to 8 lb hatchery Coho. Folks this is very very basic animal husbandry known for centuries. The only difference in raising fish or cattle is fish live in water. The laws of natural or mankind selectivity are well known even by WDFW.
