If you want to catch lots of fish, it may be beneficial to consider some artificial feeding regimen. My main question would be to find out what sort of water turnover you are expecting annually. If you have a large watershed, I have found that you can feed with less risk to having too many nutrients and consequently will be able to support more biomass to achieve your goal of lots of pounds of fish to catch and harvest. Ponds that don't have much "flow through" are much more limited in this respect.
