To me, fish food is a huge input, and one that is often unsustainable. What
examples do you know of that do it without fish food inputs (or very little)?

Almost none of that is the case for aquaponics. It is a low-input, closed loop system, very different. Fish food is the primary input, though I know of systems that use almost no purchased fish food._______________________________________________
