Cargill, Freshwater Institute partnership to improve feeds for RAS salmon farming

Tuesday, September 28, 2021

Fueled by increased global demand for salmon and the opportunity to help salmon farmers accelerate development to meet this demand, The Conservation Fund’s Freshwater Institute and Cargill announced a multi-year agreement to develop, evaluate and enhance feeds for the growing land-based aquaculture industry. This partnership builds on recent efforts between the two groups that validated the effectiveness of Cargill’s new diet for Atlantic salmon grown in land-based RAS. The partners started working together in 2018, and this new agreement solidifies the collaboration through 2023 and beyond.

Marc Turano, nutrition and technology lead for Cargill Aqua Nutrition in North America, summarized the importance of the partnership. “Our customers want the best nutrition possible. Partnering with the Freshwater Institute has provided key access to capabilities but more importantly to renowned thought leaders in land-based aquaculture production and thus, important to the advancement of science in this strategic growth area.”

The Institute provides Cargill nutritionists and researchers with access to fish, systems, research facilities, and a world-class team of scientists, engineers, and fish culturists with decades of RAS experience. In addition, Cargill provides leading-edge diet development and aquaculture feeds to optimize fish performance. Together, the partners hope to further improve land-based aquaculture's environmental and economic performance through feeds developed and tested specifically for RAS.

John Davidson, research scientist at the Freshwater Institute, who is collaborating closely with Cargill Aqua Nutrition, described the importance of ideal feeds for a successful RAS operation. “Diets developed for use in RAS should support optimal fish health and performance while facilitating good water quality and system operation. For example, feeds like Cargill's recently developed EWOS Clear for land-based salmon farming produced settleable solids in recent research trials that were effectively removed from the recirculating flow, thereby improving the fish culture environment and overall RAS operation.”

“As pioneers in fish nutrition, research and innovation, Cargill is applying this expertise to RAS and investing in bringing important new RAS products to the market. Our existing RAS feed for salmonids, EWOS Clear, is the result of our scientific and commercial teams taking a holistic approach with a focus on feed quality, digestibility, fecal stability and mineral availability. Cargill's next-generation EWOS Clear feeds will build on this and take a step further to ensure our customers can continuously operate their systems in a safe, responsible, sustainable way,” the company said.
