Global aquaculture feed supplier Skretting is poised to introduce a line 0f feed products that are specifically formulated for use in recirculating aquaculture system environments.

Skretting, which operates in five continents, is collectively calling its new feed concept RCX. Over the coming months, the company will be rolling out a range of products intended for Atlantic salmon growth and “fullly optimized for RAS.”

RCX will be launched first in North America to specific customers for Atlantic salmon, followed by other locations and species around the world.


“Skretting’s current market-leading range – RC  – has been a top performer for years, and reduced the impact of indirect waste into RAS by improving faecal stability,” said Saravanan Subramanian, a global product manager at Skretting. “The next generation – RCX – takes this one step further by ensuring consistent structural integrity through certified factory auditing.”

The feed production team at Skretting Aquaculture Research Centre (ARC) in Stavanger, Norway, has developed strict quality parameters and will audit Skretting facilities to ensure these rigorous standards are followed.

“Our team works closely with the local experts in all our plants around the world, and we conduct regular audits on our operations,” said Stuart Fyfe, operations team leader at Skretting ARC. “We have detailed analyses of the facilities that will be producing to RCX standards, and have now designed specific parameters to ensure that our customers receive optimal and consistent high-quality RCX products wherever they may be.”

The new concept fully uses Skretting’s global resources as well as existing and RCX-specific structural integrity standards.

Skretting already ensures the precise nutritional quality of feeds through a sophisticated global network, including globally-referenced near-infrared spectrometry (NIR) calibrations. “The factory certification takes our level of quality to the next level,” Fyfe explained. “We will have a zero tolerance for non-conformance on the physical quality of RCX feeds.”
