How This Grade Differs
Marine fish extract concentrate is listed as a liquid mixed-marine-fish ingredient with 30% solid content measured by refractometry and gravimetry. Compare the linked 20% liquid concentrate on the same solids basis; the linked marine fish powder is a dry ingredient specified by protein content, not liquid solid content. Confirm the current batch documents and fish-source identity before substitution.
