I think if you used catfish and hsb on a put and take basis.Tilapia or bluegill and possibly trout over the winter you could end up quite a bit of fish for the table.This is a real grey area of pond management if you ask me,most here manage for pleasure and sport and this is leaning more towards the aquaculture aspect of things.

One thing I can tell you is you're going to have to do some research and hash out a plan that fits your goals,time and budget.If you want the production from a small area,you'll have to lean towards the farming/aquaculture side,or you can give up some production and have more of a pond so to speak.
