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

Harvested Biomass Kilograms (kg)

Required number in kg.

Production Area Hectares (ha)

Required number in ha.

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

Calculate harvested live weight per hectare of production area. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Yield Kg Per Hectare (kg/ha)

Returned number in kg/ha.

• 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.

• Stocking Density

  Calculate live biomass per cubic metre of stocked water; this does not prescribe a safe species-specific density.

• Condition Factor

  Calculate Fulton's mass-length condition factor for weight in grams and length in centimetres; body shape varies by species.

• Daily Feed Rate

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