I'm preparing to begin stocking my new 2 ac. pond, pond was full last october, how many pounds of fatheads will I need to get my forage base started??Do you guys think i should add any other types?? when should I start?? Goal for this pond is to have quality hy.BG,possibly 50-50 lmb. smb. preadators...Origanally wanted crappies also, but sounds like a bad move from all that I've read here...what do you guys think???
