More value from every fish
Only about half of most fish ends up as edible meat. Haarslev helps you turn the other half — heads, frames, trimmings, by-products and whole industrial catches — into high-value meal, oil and ingredients, with less energy and a smaller footprint.
World-leading processing technology for land-based plants, ship-based systems and the fast-growing aquaculture sector.
The world's fisheries are changing fast — and so is what your operation has to do.
Wild capture has largely plateaued; the technical gains left in it are marginal. Stocks are tighter, legislation is stricter, and food-security and corporate-responsibility expectations keep rising.
Meanwhile aquaculture has doubled in a decade and is heading towards roughly half of the world's fish supply. The whole context for fish processing is shifting with it.
Haarslev builds the processing capability that lets you move with that shift — recovering more value from every input, on land, at sea, or downstream of a fish farm.
Turn processing challenges into commercial advantage
Haarslev helps fish processors build value and margin by turning everyday operating problems — variable inputs, energy costs, tightening rules, hard-to-fill shifts — into responsible, repeatable, higher-value output.
The question we help you answer: can your operation run more efficiently, on less energy, for better and more consistent results — with healthier margins? For Haarslev customers, the answer is yes.
How you benefit
Better, more consistent product
More effective processing means steadier specs and higher yield, batch after batch.
Lower energy and operating costs
Energy-efficient hardware plus heat recovery and recirculation cut your biggest variable cost.
Less dependence on scarce labour
Effective automation reduces headcount pressure and training load.
More revenue-earning uptime
Robust, reliable equipment keeps the line running.
New revenue streams
Higher-spec outputs open premium markets and new products.
Compliance, certification and ESG, documented
Full-spectrum regulatory cover and the data to prove it.
Haarslev systems are engineered for easier upscaling, greater versatility and better future-proofing.
Three ways Haarslev adds value across the fish supply chain.
Aquaculture Processing
Recover and upcycle value from farmed catches, processing waste, aquaculture sludge and non-viable fish — with flexible, scalable plants you can adapt as the sector grows.

Explore →Haarslev is the world's leading supplier of the technology fish operations use to convert offcuts, by-products, waste and offal into fish meal and oil.
We design, build and deliver systems known for reliability, energy efficiency, safety and forward-looking compliance with local and international standards. That lets our customers improve product specs, cut energy use, deliver on ESG targets and take advantage of new technical and commercial opportunities.
From a single machine to a complete plant.
Haarslev's range runs from individual specialist machines up to fully integrated processing systems, covering:
- Efficient fish meal and oil plants — on land and ship-based
- Purpose-built solutions for the fast-growing aquaculture sector
- Preparing fish- or surimi-based inputs for processed-food factories
- Right-sized facilities that put processing where the logistics make sense
Every system is backed by the specialist know-how and service that keep it running at peak efficiency — for a long time.
We keep your results consistent — and not just on day one.

What plants like yours report
Customers running Haarslev installations report fewer unplanned stops, calmer control rooms, and less worry about what's happening on the line — and why. Supervisors start turning in steady production. Crews start trusting the line, shift after shift. And the numbers move: steam use drops, odour events fall, output specs get easier to hit, yields become more repeatable, and targets and budgets start to feel realistic again.
