Seems so strange to me that the general consensus is that salmon and steelhead are going away along with our opportunities but no one is willing to change.
Random spawning is much worse than selective spawning if selective spawning is done correctly. Your stubborn attitude to continue on the same path and not admit wrong prevents things from getting better. Are you sure that you do not work for WDFW?
The other change that I advocate for is nutrient enhancement with dead hatchery carcasses. To decrease cost I would suggest spawning the males and then releasing them back into the river ALIVE (and as late as possible to minimize any interactions with native fish) after milking them out.
Productivity is different than efficiency.
