The Aquaculture Stewardship Council (ASC) is aiming to approve a standard for plant ingredients used to produce aquaculture feed products.

"We are looking into a way of how we should start to address plant ingredients within aquafeed," Michiel Fransen, head of ASC Standards & Science, told IntraFish.

While traditionally there has been pressure on the sustainability of fishmeal and fish oil, the aquaculture industry has tended to ignore the fact that soy, corn and wheat may have an equal if not larger environmental and social footprint, in the ASC's view.
