How to Use This Calculator
  1. Enter Total Fish Biomass, Water Temperature, and Base Feed Rate.
  2. Review the Daily Feed Required (lbs) result.
  3. Use Weekly Feed Required (lbs) and Monthly Feed Required (lbs) to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Total Fish Biomass
Combined weight of all fish in the pond or system in pounds.
Water Temperature
Current water temperature in Fahrenheit. Feed rates drop in cold or extremely hot water.
Base Feed Rate
Target feed rate as percentage of body weight per day. Typical range: 2-5% for grow-out.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Total Fish Biomass = 5000, Water Temperature = 78, Base Feed Rate = 3 = 3 input(s) provided
  2. Calculate Daily Feed Required
    150 = 150
  3. Calculate Weekly Feed Required
    Weekly Feed Required
    1050 = 1050
  4. Calculate Monthly Feed Required
    Monthly Feed Required
    4500 = 4500
