There most certainly are rivers where there is no hatchery supplementation,such as a handfull of small streams near my home in California. These rivers have small runs of self sustaining wild(native) steelhead. They put the hatchery bananas to shame. I agree with the all hatchery fish must die statement. I don't need to bonk a fish for the dinner table,I say discontinue all hatcheries,problem solved. Hatchery fish aren't bringing back the runs.

I know of another little river in NorCal where the watershed is rebounding from past logging operations,it's all catch and release,and the wild steelhead population is on the rise. Every year quite a few strays from another river are caught here. they are bananas. Garbage fish. They need to be eradicated,I certainly shudder to think they may be spawning with the bad ass natives there.
