Semi-auto fish fillet machine for 20–2000g fresh/semi-thawed fish. Precise 3-piece cut, SUS304 body, 60–120 pcs/hr. Ideal for mackerel, saury, grass carp. Custom sizes available.
The 328 Medium Fish Fillet Machine is a high-efficiency, semi-automatic solution designed for small to medium-scale seafood processors, fish markets, and food factories. It specializes in accurate three-piece filleting—cleanly removing the central backbone to yield two intact, bone-free fillets from a wide range of common commercial fish species.
Engineered for fresh or lightly thawed fish (20g–2000g, up to 12cm thick), this machine dramatically reduces manual labor, boosts processing speed, and minimizes handling time—helping preserve the natural texture, color, and freshness of the fish.

Precise Three-Piece Filleting
→ Cleanly separates left fillet, spine, and right fillet in one pass
→ Minimal meat loss, smooth cut surface
Wide Fish Compatibility
→ Handles mackerel, saury, Spanish mackerel, grass carp, blackfish, yellow croaker, loach, and more
→ Adjustable blades accommodate varying sizes and shapes
Freshness-Preserving Efficiency
→ Processes 60–120 fish/hour (depending on size)
→ Less human contact = lower contamination risk & better shelf life
Customizable & Scalable
→ Standard capacity: 20–2000g, height ≤12cm
→ Larger models available on request for bigger species
