The wild fish are pretty expensive also. We are spending 150 million a year on habitat restoration just in Puget Sound. They are not spending that to recover hatchery fish. So how much is that per fish that we don't even fish for? The statewide cost estimates for steelhead and salmon habitat recovery is 5.5 billion dollars from 2010 to 2019.
And I have no issue with the money being spent. I would like them to spend more to restore the habitat. But it may not be enough.

The bottom line is only 20% or less of the smolts leaving Puget Sound make it out. We are losing 80% before they get to the ocean. It is being studied. Look up the Salish Sea Marine Survival Project. Read the reports and they also have video or two.
Nothing will save these steelhead unless we figure this out and ways to mitigate the losses. And it has nothing to do with hatchery fish. It is an in Puget Sound and the Salish Sea issue.
