Fish Fillet Yield Calculator
Not all of a fish's weight turns into dinner. Skin, bones, head, and guts all cut into your usable meat. This calculator uses your total catch weight and an expected yield percentage to estimate how much fillet you'll actually bring home.
About this calculator
Estimate how many pounds of usable fillet meat you'll get from your total catch weight based on species-typical yield percentage.
Frequently Asked Questions
What yield percentage should I use?
It varies by species: round fish like walleye or bass often yield 30-40%, while flatter fish or larger fish with thicker fillets can yield higher. Adjust based on your experience and species.
Why is the yield so much lower than the total weight?
Heads, bones, skin, scales, and internal organs all add weight that isn't part of the edible fillet, often 60-70% of total weight.
Does filleting method affect yield?
Yes, a more precise fillet technique that hugs the ribcage closely will improve yield compared to rougher cuts that leave meat behind.
