Nuseed has completed three commercial-scale fish trials with industry, confirming the efficacy of Aquaterra Omega-3 canol oil as a partial replacement for fish oil in aquaculture feed.

The trials, undertaken in Chile, indicate inclusion of Aquaterra in feed results in decreased fish mortality and reduced Fish In Fish Out (FIFO) and Foraged Fish Dependency Ratios (FFDRo). The expression of EPA+DHA in the fillet and sensory analysis are equivalent in Aquaterra and fish oil diets, signifying Aquaterra meets consumer taste and nutrition expectations.

“This study demonstrates Aquaterra is a highly effective, sustainable complement to fish oil for the aquaculture industry which, until now, has been reliant on limited marine ingredients. It’s the first step in Nuseed addressing global challenges through the power of plants and agriculture,” said Benita Boettner, Nuseed global general manager Omega-3.

Aquaterra is the world’s first land-based source of long-chain omega-3 fatty acids, produced by Nuseed to deliver the nutritional benefits of microalgae via its proprietary Omega-3 Canola. Nuseed partnered with salmon producers and feed suppliers to conduct commercial scale feeding trials in the largest study of its type with a new feed ingredient. The trials were conducted over an 18-month period with 3m fish across three sites with results confirming those from independent trials conducted by the Norwegian Institute of Food, Fisheries and Aquaculture Research (NOFIMA).

Aquaculture depends on wild fish ingredients to feed farmed fish, and these resources are insufficient to meet the needs of industry growth. Aquaterra supplies a renewable and scalable source of omega-3 nutrients while reducing pressure on ocean environments.
