By year 4 nitrogen mobilization from the feed input is supporting a food chain that can support 423 lbs of fish. But the carrying capacity is 1129 lbs and so feed is supporting 706 lbs of fish on its first pass. So another way of stating the same thing is that food chain effects from the utilization of feed wastes increased the carrying capacity by roughly 60% as a secondary effect.
That is a very interesting concept that you are describing.
If my pond is initially too nutrient lean, then I can fairly readily turn the balance to my favor with a feeding program, and the secondary effect of the nutrient fertilization will also help the rest of the food chain.
By having an artificial "control knob" it might even be easier to run closer to maximum carrying capacity and then pull the fish back from the precipice by turning off the feeder compared to NOT being able to cut back the food chain in a naturally nutrient-rich pond. (I am not planning to run near maximum carrying capacity, but mistakes do happen.)
P.S. Thanks for taking the time to type up your long evaluations.
