Skretting’s pilot-scale feed technology plant explores the latest production technologies, new feed formulations, potential raw materials, equipment optimization and new production evaluation methods, as well as producing sample batches of prototype feeds.

Stavanger, Norway-based Skretting, a 100+ year-old leader in the manufacture and supply of aquaculture feeds for fish and shrimp, has announced that they are now offering aquaculture feeds containing algal oil that consists of “unprecedented levels” of the two essential long chain omega-3 fatty acids, EPA and DHA, thanks to a joint development partnership with Royal DSM, based in the Netherlands, and Evonik Industries, of Essen, Germany.

The trio’s new generation of technology is currently piloting an alternative for the finite supply of traditional fish oil for the aquaculture industry. Skretting considers the new marine algal oil a breakthrough in achieving this goal.

The 3-way partnership builds on Skretting’s more than 20 years of extensive R&D in the application of fish oil alternatives in salmon and trout feeds for optimum growth and health; Royal DSM’s global science-based activities in health, nutrition and materials; and Evonik’s leading expertise in specialty chemicals — all three companies demonstrating long-term commitments to improving sustainability within the aquaculture industry.

One of the principal findings in the joint development was the identification of a specific, naturally occurring, marine alga that contains both EPA and DHA. The new marine algal oil is produced by natural algae from the ocean and cultivated in controlled, land-based facilities. The resulting product is currently approved for use in Europe.

Both fishmeal and fish oil will remain important feed ingredients, says Skretting, however marine algal oil allows them to offer more flexible formulations for their customers. Their MicroBalance® concept allows Skretting to be increasingly flexible with feed formulations.

Skretting announced at the start of the year that it had become the first aquaculture feed company to develop commercial salmon feed formulations that were completely fishmeal-free and delivered equal performance in terms of fish growth and health.
