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.

Feeding Days (days)

Required number in days.

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

Calculate total feed allowance over a fixed number of days at an unchanged daily ration. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Period Feed Kilograms (kg)

Returned number in kg.

• 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.

• Protein Requirement

  Calculate protein delivered by a daily feed ration from the feed's stated protein mass percentage.

• Energy Requirement

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

• Feeding Frequency

  Find the minimum whole number of meals to distribute a chosen daily ration without exceeding a chosen mass per meal.
