Frequently Asked Questions
What is seafood yield?
The percentage of a whole fish or shellfish's weight that's actually usable after trimming, filleting or shucking, the rest is bone, skin, shell or waste.
Why does effective cost per kg matter more than the purchase price?
A £10/kg whole fish with a 50% yield really costs you £20/kg for the part you can actually serve, the purchase price alone hides how much waste you're paying for.
How do I measure usable weight?
Weigh what you're left with after trimming or filleting, on the same scale you weighed the whole purchase on.
