Filleting & Slicing Machines

Recovery varies by species, fish condition and machine setup, with well set machines on whitefish and salmon achieving yields competitive with good hand cutting at many times the speed. Blade sharpness and guide adjustment influence yield more than machine age. Ask the seller for yield data from recent operation, since that reflects the actual machine rather than the brochure.

Every filleting machine has a working size range, and fish outside it either jam or fillet badly. Compare the machine's specified range against your typical catch profile, including seasonal variation. Wild fisheries with wide size spreads need machines with fast adjustment or need graders installed upstream.

Blades and blade drives come first, followed by fish guides, belts and the water lubrication system that keeps fish moving cleanly. Look for corrosion around bearings and electrical fittings, the usual casualties of salt exposure. A test run with fish, or recent production footage, tells you more than any static inspection.

Within a family, often yes: a whitefish machine typically covers cod, haddock and saithe with adjustment. Across families, no, because body shape drives the cutting geometry. Processors handling both whitefish and salmon run separate machines, so plan your line around the species mix you actually process.

The main manufacturers maintain spares and service for machines across decades of production, and independent fish machinery engineers cover the main processing regions. Ask the seller which service organisation maintained the machine and whether manuals and spare blades transfer with it. A machine with a documented service relationship is worth a premium.
