Guys the concept of carrying capacity or standing crop is measuring fish only not total biomass. If you added the plant life and other animal life the numbers would be many times the fish # and be at any point in time the total energetic input in the pond. Like Rainman above and Bruce in an earlier archive post discuss the total energetic input/output (total biomass) in a pond which stays relatively stable and only changes form. There are some things that change total biomass. More water , more sun and better chemical fertility. See the link below.

By definition anytime you add fish without taking some out you have increased the standing crop.

I highly recommend this thread. Bob said this about it - " This has to rank in the top ten best threads ever on this website. Good stuff, guys."
