What is the dynamic carrying capacity of a 1 acre pond (expressed in pounds per ac. ft.), that is described below; and how can I determine that I am staying near (say between 80 and 90%) carrying capacity?
Key word being dynamic. Going to always be changing. 100% capacity your fish biomass in a very fertile pond would be 500 lbs. You cannot determine you are staying near 80 and 90 percent. At best you can try and stay in your desired range with selective harvesting. I'd go with 400.
Now how much would that carrying capacity change if there was no supplemental feeding? (again expressed in pounds per ac. ft.)
Hmmm. No food changes the entire dynamic of the pond, about 350. Your goals down to 275.
How much would the carrying capacity change if both supplemental feeding and aeration were not present?
Feeding is a large increase of biomass. Aeration is activity, fish slow but I think the change in biomass would be insignificant. Temp would be a bigger factor. I am thinking 30%.
Am I correct in my understanding that carrying capacity means total biomass?
Carrying capacity is a measurement for biomass. As in how much? We have been talking total fish carrying capacity. Could be a species of fish, frogs, even plants. You overload your plant carrying capacity, you may decrease your fish carrying capacity. No, carrying capacity does not mean total biomass.
If that is true, then how do I figure what percentage of the total biomass should be fish?
Total biomass can be measured in the term carrying capacity. So I'd say false. Looks like you ask on the pondboss forum.
