Very nice fish and a respectable fish anywhere.-- they all are
You and your Dad must have had a blast catching them
The fins on the bottom may have been clipped if it was a stocked trout so that fisheries folks can keep track of different sources (different hatcheries or genetic strains of fish) or timing of stocking (early season, later season etc). They'll use a "code" so that if the adipose fin (fatty flap fin near the tail) is clipped it means one thing, if the left ventral (bottom) fin it means something else etc. If they do a creel census or electrofishing later they can tell what survival rates different strains have, how long they last before getting fished out, holdovers from previous years etc.
