Most record fish seem to be of the full of eggs variety. If you ever see photos of yellow perch record fish, they are all grotesquely fat:
I think most of our trout records are bogus. Should really separate native/wild from stocked/hatchery fish. There really is no comparing the two - especially brook trout which rarely exceed 12" or go over 1lb under normal conditions(i.e not being fed pellets or kept in some spring pond)
