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

Daily Feed Kilograms (kg/day)

Required number in kg/day.

Feed Protein Percent (%)

Required number in %.

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

Calculate protein delivered by a daily feed ration from the feed's stated protein mass percentage. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Dietary Protein Kg Per Day (kg/day)

Returned number in kg/day.

• 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.

• Daily Feed Rate

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

• Energy Requirement

  Calculate energy supplied by a feed ration; it does not infer a species' metabolic requirement.

• Feed Allowance

  Calculate total feed allowance over a fixed number of days at an unchanged daily ration.
