Just because fish were planted, just because they spawned, does not mean that they have been successful at introgressing into the native stock. Chambers Creek steelhead is a good example. In many rivers they are simply not successful at surviving. They may compete as fry, which is not good, but they eventually die.

The habitat and environment are not the same now as it was 200 years ago. A "True Native" might not be able to survive, now. What I would like to see is systems with purely wild fish; let what can survive make up the run.
