I read a bit further into your post and seen a flag or 2... Your BG probably are to a point that growth will slow way down because they a gonna be focusing on filling the void, producing as much offspring as possible-their energy is put towards that task.
The flag I see is the July addition of Bass.
Why not let those BG that are becoming sexually mature fill that pond with billions of BG yearlings to provide a larger assortment for higher growth potential and wait until fall for stocking bass?? Am I out of whack here guys?
