Yes, stocked 8 8" HSB. I have seen no evidence of their survival. The experiment completely imploded when I forced 9 acre feet of water through a .2 acre pond.
Unfortunately I have no advice to lend anyone in regards to HBC at this time. I have seen no evidence of a spawn, but I limit fishing at my pond 4x monthly and I am never fishing minnows...typically looking for my HSB and SMB. This winter I will be jigging minnows for YP and I should be able report more on the growth of the HBC.
If you are interested in stocking HBC do so in a pond that will not drain into any other BOW you don't intend them to enter....obviously.
