So I'm sitting here looking at my ponds with 16"s of ice on them. I'm considering adding some structure out on the ice, and I'm thinking about why 15% structure is the rule I'm told. In any lake or pond the fish spend most of their time around structure. So I'm thing "If some is good, more is better". More bio-film, more food chain, more fish. So we want 85% just water without fish? The only justification I can think of is water quality as the open water will be wind driven and currents will result adding O2 and turning over the water. After all a Bass can live in an aquarium as long as the water quality is good. I have great respect for the people on this forum so I know there are reasons not to add to much structure. What say you fellow pond bosses?
