Many of the managers at the hatcheries were very creative. At one time, they crossed Chinook and Coho. Planted these in ponds with no egress. What they got was a piscivorous diet from the Chinook and the desire to commit suicide on hardware from the Coho. The fish cleaned out stunted populations of Yellow Perch. We have a number of lakes that have no egress that would probably a "thinning" of the smaller species and converting that to consumable salmon.

Oncy May remember a lake where coho were net pen reared, released into the lake, and then turned loose. Over a few years of the net pen program they came close to removing the perch. We should use this knowledge.
