You mention the loss of ecosystem function when we manage for hatchery fish and over harvest the wild.

Starting with LCR Tules why not manage each hatchery stream for a combination of ecological and hatchery needs. Use, say, 1kg of spawner per square metre of stream and then add on the number needed to meet program. That way you can produce the hatchery fish, have high harvest rate fisheries, and still meet the ecosystem need for nutrients.

I would add to that a proposal that every fully blocking dam in the anadromous zone (let's start with Coulee) that we pass a million Chinook to meet the fishery needs of natives (whose right to fish is geographically fixed), other people, and the ecosystem. No need to have downstream passage as the goal is ecological replacement of adults.
