Bridging the raw material gap
As the global population continues to grow, there is increasing focus on aquaculture to provide the protein to feed the world. At Skretting, as one of the largest aquaculture feed suppliers in the world, we see that we have an essential role to play. A 30 million tonne projected increase in aquaculture production means there will be a need for an additional 45 million tonnes of raw materials. So where will they come from? In this series, we deepen on some of our ongoing activities in this arena, exploring novel ingredients and some of our most important partnerships.
Part VI: Omega-3 from marine algae – an innovative solution for increased protein production
Skretting feeds containing no fishmeal or fish oil can successfully grow salmon to harvest size with no negative impact on fish performance or health while retaining the nutritional content of the salmon fillet.
This has been possible due to the innovation from our collaborator Veramaris, a joint venture between DSM and Evonik, to produce industry-first marine algal oil containing both long-chain omega-3 fatty acids, EPA and DHA.
Through our collaboration, the dream of being infinitely flexible with feed ingredients became a reality. “Veramaris produces the two essential omega-3 fatty acids EPA and DHA from natural marine algae for animal nutrition. We are happy to see our pioneering algal oil used in Skretting’s commercial feeds,” says Karim Kurmaly, CEO at Veramaris.
Made possible through expert knowledge
Fish oil has been difficult to substitute out of fish feed because previously the only source of EPA and DHA was small pelagic fish harvested from the ocean. Despite being currently in good supply, fish oil is a limited resource and in high demand from a number of other feed, food and pharmaceutical sectors. However, fish cannot produce large amounts of long-chain omega-3 fatty acids. The original source is marine microalgae. Through the culture of microalgae, the fatty acids can be obtained while bypassing the marine food chain entirely.
“To feed the world in decades to come we will need to produce more protein using fewer natural resources – aquaculture alone must double production in the next 30 years,” says Jose Villalon, Nutreco Sustainability Director. “To achieve this, we need to reduce our dependence on natural resources that will be limited in availability as the industry grows, such as the fish oil we use in salmon feed. Finding alternative ingredients requires innovation – and we can only drive this through close collaboration and strategic partnerships across the value chain.”
Sissel Susort, Skretting Global Product Manager agrees that the multi-stakeholder approach has a lot of potential and can help Skretting introduce or help scale up much needed oil, and protein, ingredient sources for the aquaculture industry. “This is necessary as we work to increase protein production and feed the growing global population – and it is important to be at the forefront rather than wait until a crisis is upon us. Collaboration and innovation are essential to help us fulfil our mission of Feeding the Future.”
