It will be interesting to see how your pond fairs... I suspect with the good number of large sized bass and catfish you have to help control their numbers you'll be OK in the short term. I think you will be OK as far as your bass numbers go. Your BG and other panfish will take a hurting though. I am watching a 4 acre pond that was invaded by gshad 6 years ago go through a transformation right now and am very interested how things play out. Keep us updated... When did you stock the gshad into your pond? Do you have data of Wr on bass and other species in your pond before they were stocked? Would be interesting to compared the before and after...
