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.

Max Feed Per Meal Kilograms (kg/meal)

Required number in kg/meal.

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

Find the minimum whole number of meals to distribute a chosen daily ration without exceeding a chosen mass per meal. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Minimum Meals Per Day (meals/day)

Returned number in meals/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.

• Feed Allowance

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

• Protein Requirement

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