I have a nearly 2 acres pond stocked with 2000 copper nose bream and 6000 fat head minnows in Jan 2012 and 120 tiger bass in June of 2012. Well 4 years later it is nearly impossible to get a bass bite out of it. Millions of small bream and plea to around a pound. Biggest bass we have caught is about 5 pounds but you might catch 1 every couple days in an hour of fishing. I have kept a few bream and maybe 20 bass. Should I keep more bream?
