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

Fillet Weight Kilograms (kg)

Required number in kg.

Whole Weight Kilograms (kg)

Required number in kg.

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

Calculate recovered fillet mass as a percentage of whole-fish mass. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Fillet Yield Percent (%)

Returned number in %.

• 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.

• Dressing Percentage

  Calculate dressed yield as a fraction of whole-fish mass under a consistent processing definition.

• Gonadosomatic Index

  Express gonad mass as a percentage of whole-body mass.

• Hepatosomatic Index

  Express liver mass as a percentage of whole-body mass.
