You seem to think that there are a large number of unclipped hatchery fish.
Can you supply any data that shows a low ad clip rate?
Or is this just a gut feeling?
All the numbers I've read seem to indicate your wrong in your assumptions, but If you have hard data then let's see it.
Here are the hatchery ad-clip release summaries for the CR uprivier spring stock. Brood years 2004 and 2005 will yield the majority of what we all see out there.

It comes out to about 90%. Maybe just a tad under.
