Skretting Aquaculture Research Centre (ARC)

Where science meets industry

The Skretting Aquaculture Research Centre (ARC) is the global research organisation for Skretting. For more than a quarter of a century, ARC’s large, industry-leading team of scientists and experts specialising in fish and shrimp nutrition and health as well as feed production technology has been delivering innovations that define and support the progress of aquaculture.

ARC facts

A selection of our innovations


Protec is our functional feed for farmed fish that helps shield skin, gut and gills. It also supports the immune system, provides the building blocks for new cells and optimises the balance between fish, microbes and environment

About Protec


Skretting is the market leader for diets specifically designed for recirculating aquaculture systems. Recirculating Aquaculture Systems (RAS) are land-based aquaculture facilities that reuse water by cycling it through a filtration system so it can be used again.

About RAS


MicroBalance® encompasses Infinity, MicroBalance FLX and N3, and is about the right nutrients, not specific raw materials. This allows us to replace feed raw materials without impacting performance, welfare or fish quality, providing unprecedented formulation flexibility.

About MicroBalance

Innovation process

Idea gathering

The pairing of our global presence and local market insights enable us to prioritise research that best fulfils the specific requirements of our customers as well as the broader needs of the aquaculture industry


Every concept we develop undergoes a comprehensive performance evaluation and accredited trial process


Our prototype formulations are subject to large scale testing in commercial environments to verify whether they can perform as intended when introduced to customers' production systems


New feed solution

Collating the findings of our research, all products are appraised to establish if they can be further improved upon and applied to other species and markets

Follow up

Regular consultation with customers ensures our products consistently meet commercial expectations. In addition, our AquaSim management tools help them to optimise farm performance
