Simple definition: Carrying capacity is the maximum fish biomass a pond can support without water quality breaking down.
Detailed Explanation
It depends on pond volume, filtration, aeration, and water exchange, not just surface area. A well-filtered, well-aerated pond can carry more fish than an identical pond with weak filtration.
Why It Matters
Pushing past carrying capacity is one of the most common reasons ponds develop chronic water quality problems, even when everything else is done right.
Practical Example
Adding a stronger filter or pump can raise a pond’s practical carrying capacity without changing its size.
