It really depends on your pond/lake. Its productivity will be key. So it all depends. Walt could be right as to what he experienced but it may be different with your situation. I have seen lakes in central Fla with carrying capacity of 2500-3000 lbs per acre loaded with big fish including both shads , CNBG , shiners and tilapia all mixed together. I have also seen lakes that are lucky to have 100 lbs of fish per acre.
