Tony, if I don't hit 2# by next Spring, I'll be stocking Yellow Perch. This "trophy" BG deal has has been my main focus for 2 years now. Water, habitat, cover, staggered feeding schedules and food sizes, I'm trying it all. What has happened is tons of 10+" CNBG that hold in an area that was created just for them. I'm very happy with the results, but to me, getting one 2# is a hundred times harder than getting 50 1#'s.
I have learned that length is not a determining factor in weight with CNBG. I've caught 5-6 CNBG this year that were over 11", and none of them were among the heaviest caught.
This next Spring I'll start aging by scales, and hope to find the heaviest CNBG at 3-4 yo. That "should" give me 2 more years to add more weight on them before any decline.
