Russian fish processors are cutting costs by replacing salmon with trout in half of their fish products, according to Ilyas Adiatulin, Deputy Director of the National Center for the Safety of Aquatic Products and Aquaculture. The fraudulent replacement is found in deeply processed products like rieta, and there are concerns about the substitution of cod with cheaper fish like pollock. However, no such violations have been identified in canned saury this year, after they were found in every third can in the past two years.
