What each input means

Pond Size
Total water surface area of the pond in acres.
Stocking Density
Total fish biomass per acre in pounds. Intensive systems may exceed 5,000 lbs/acre.
Water Temperature
Average water temperature in Fahrenheit. Warmer water holds less dissolved oxygen.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Pond Size = 2, Stocking Density = 3000, Water Temperature = 80 = 3 input(s) provided
  2. Calculate Aeration HP Required
    5 = 5
  3. Calculate Total Fish Biomass
    Total Fish Biomass
    6000 = 6000
  4. Calculate Recommended Aerators
    Recommended Aerators
    3 = 3
