That's why they are testing commercial selective gear to bring the 40% mortality rate down of gill nets. Trying to help eliminate some of the waste of drop out and by catch along the way as well, while trying to keep hatchery off spawning beds.

I read that sports could/should try to drop their mortality rate as well on this thread.

Probably not a popular idea, but using artificial bait only like C&R rivers to help with less mortality issues. What the mortality rate number drops to ---- I have no idea---- but it does keep some rivers open for fishing in this state that would be normally closed.
