Warren I really have to say that I love you take on this classic argument. I myself have always thought "wild vs stocker" only as there birthplace. The fact that the fish are stocked does not remove the engrained natural instincts that make them wild. Now if a stocked fish acted in a different way then a wild fish in a natural instinct. For example the males waiting in one location to be milked of sperm to fertilize eggs. I could then say that the stocked fish was different, but this does not happen nor say it ever will. So in reality a stocked fish is no longer a stocked fish after it is fending for itself and following its natural instincts. The term stocked could also be implied to any fish that has been artificially introduced to a location not normally found to have this type of fish. One might consider a stock fich to be the standard fish in a location. Thus not even referring to its place of birth.
This leads me to wonder why does it matter.
