Even if we restore the habitat and the wold fish the simple mathematics of management produce fewer consumable fish. Or game. Broodstock requirements for the farmed products are significantly smaller than for wild. And, if we preserve/restore the wild salmon, where are we going to put the people?

Undam the Columbia and tribs and we get back the wild fish. Where will the power and irrigation water come from? King Coal? Maybe DT is right. Remove the dams and bring back coal.

Restore the Ssacramento and San Juaquin for wild salmon. Again, where does the drinking and irrigation water plus power now come from. And, where do all the people in the floodplain (most of the whole Central Valley) get moved to?

The problem is people.
