ML & Bruce :

ML -- Bruce provided the answer to age determination - based on year rings on scales or observation (not as good at that as BC) or knowing age of birth + time in pond when all the same age (working with and looking at a lot of BG with known age).

Bruce -- I know the BG are 2 1/2 +- that is why I compared to 2.5 yr. old BG here. I am comparing to norms not genetic picked BG. Yours are genetic picked (selectively breed by you) and ML's are to buy his hatchery , I think. ewest
