Why not just cut a deal with the Gill netters? They can trade in X amounts of gill net licenses for X amounts of net pens to rear the chinook/coho in the Columbia River!

They get there fish, we get our fish! We can cut back on our hatcheries because they will get their share of the pie in their net pens. Zero competition with wild and endanger species. River cleans most of pollutants and pens could be altered in locations as needed.

Now what's wrong with this basic idea?
