The UK’s fresh king prawn industry starts here.
Rastech designs and operates land-based aquaculture systems. Eden Valley Prawns brings that technology to the plate with fresh Scottish King Prawns, grown on land in Fife, harvested to order, and delivered chilled — never frozen.
Eden Valley Prawns describes itself as the UK’s only King Prawn farmer.
Harvested to order and delivered chilled rather than stored frozen for months.
Rastech states its solutions use around one tenth of the water of traditional RAS.
The Eden Campus facility is largely self-powered by solar PV with local generation support.
Engineering credibility with a product people can actually taste.
The landing page should make one thing clear immediately: Rastech is not just theory, and Eden Valley Prawns is not just another seafood brand. The technology is operating commercially, and the product proves the system in the real world.
The technology platform
A Scottish aquaculture technology company focused on land-based, closed-containment systems where biology, engineering, energy use, and food production meet.
The fresh prawn brand
A family-owned Scottish producer growing King Prawns on land at Eden Campus near St Andrews, serving restaurants, food service partners, and direct customers.
A cleaner alternative to the imported frozen prawn supply chain.
- ×Typically grown overseas, frozen, transported long distances, and stored before reaching the UK customer.
- ×Often disconnected from the customer, with limited visibility around farm conditions, treatment, and freshness.
- ×Can rely on preservatives or treatments that many customers increasingly want to avoid.
- ✓Grown on land in Scotland, harvested to order, and delivered chilled rather than frozen.
- ✓Fully contained system designed around animal welfare, food safety, product quality, and lower environmental impact.
- ✓No antibiotics, sulphites, polyphosphates, or routine chemicals — just fresh prawns.
Land-based aquaculture designed around real constraints.
Rastech’s technology story is strongest when it stays practical: renewable heat, circular energy recovery, site-tolerant modular buildings, solar-backed power, and smart monitoring that supports welfare and operational efficiency.
Anaerobic digestion
Renewable heat and biosolids management brought into one circular design for lower operating costs and stronger sustainability performance.
Passive heat recovery
Outgoing effluent can be used to warm incoming exchange water, cutting water heating costs while reducing wasted energy.
Waste heat integration
Low-grade heat sources can maintain warm-water RAS buildings even in challenging external temperatures.
Onsite generation
Low-energy system design helps farms run with local generation, solar PV, and microgrid thinking rather than full grid dependency.
Modular deployability
Buildings are designed to be site-tolerant, fast to erect, and easier to deploy without heavy foundations or complex underground works.
AI & machine vision
Sensor data and machine vision support heat movement, feeding efficiency, biomass monitoring, health insight, and welfare-led operation.
From closed-containment system to chilled delivery.
This section turns the production process into a clear customer story. It explains the benefit without drowning the visitor in technical detail.
Grown on land in Fife
Prawns are grown in a fully contained recirculating aquaculture system at Eden Campus near St Andrews.
Powered by Rastech systems
The operation uses thermally efficient buildings, clean water handling, circular design, and energy-conscious engineering.
Harvested to order
Instead of freezing and storing, prawns are harvested for demand and prepared for chilled dispatch.
Delivered to chefs and homes
Fresh King Prawns are supplied to restaurants, food service partners, and direct customers across the UK.
