I still think common carp are the way to go... There is a reason the rest of the world uses them! If you are trying to crank out pounds of fish to eat common carp are it. My dad's best friend who is a complete survivalist the end of the world is coming sort of guy has 4 ponds on his property. He raises common carp in one. There was 14 people living on his "compound" lots of mouths to feed and the carp keep up with the demand.

But if you don't like eating carp, you don't like eating carp... I have to say, when from a clean BOW they are good eating. He also has a LMB/BG pond, a CC/FHM pond and a trout pond.
