Fishmeal-free Atlantic salmon feed formulation shows promise
A recent study evaluated the effects of a fishmeal-free diet on Atlantic salmon performance and fillet quality during successful growout to market-size in a commercial-scale, land-based, closed-containment system using water recirculation technology. Test fish performed well, with 97 percent survival during the 10-month growout period.
