It wouldn't necessarily only apply to ponds that are fertilized or fed. Some waters are hyper-eutrophic without feeding or fertilizing. Many species of fish are unable to persist in those waters while others thrive. Often, scientists monitoring nutrients in water consider them pollutants.
I think edge habitat is important. Examples of edges are terrestrial-littoral & littoral-pelagic. So food production can obviously be increased by having increased perimeter relative to surface area. On the other hand, there is risk the volume is too restricted when there is too much perimeter. I can't help you with what is optimal because I don't know. But if I had to guess, I would suspect that higher standing weights probably favor lots of edge but that carrying capacity favors lots of euphotic volume.
