Use this calculation to compare aquaculture production, feeding, growth, water-quality, or hatchery measurements collected with the same definitions and units.

Feed Conversion Ratio (kg/kg)

Required number in kg/kg.

Feed Price Per Kilogram (currency/kg)

Required number in currency/kg.

The cited overview of Aquaculture supplies background for the terminology and domain context used by this tool.^[1]

Estimate feed cost per kilogram of wet biomass gain from FCR and feed price; other production costs are excluded. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Feed Cost Per Kg Gain (currency/kg gain)

Returned number in currency/kg gain.

• Species, life stage, temperature, salinity, system design, sampling method, and management practice can materially change aquaculture measurements and suitable operating ranges.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Complement the calculation with calibrated water-quality instruments, representative sampling, feed and mortality records, and species-specific guidance from qualified aquatic-health or production professionals.

• FCR

  Calculate apparent feed conversion ratio as feed consumed divided by wet biomass gain; natural food can affect interpretation.

• Daily Feed Rate

  Convert a chosen daily feeding percentage of live biomass into feed mass per day.

• Oxygen Consumption

  Estimate hourly stock oxygen demand from a measured or separately specified per-kilogram rate.
