Cargill has found a way to help aquaculture companies raise EPA and DHA omega-3 fatty acid-rich fish in a more sustainable way, the company said Monday.

The company is in development to create a new type of canola that it says could replace fish oil in aquaculture feed and "ease harvest pressure on wild fish populations that currently supply much of that oil."

In trials Cargill conducted with salmon in Chile, fish oil was totally replaced with the EPA/DHA canola with success.
