From our friends at Plymouth Springs Fish Company:
Wisconsin farm to your table!
"At Plymouth Springs Fish Company, We practice sustainable fish farming in a natural pond setting utilizing the ice cold Wisconsin spring waters that flow from the earth into our ponds. Our farmers live on the farm and tend to the fish multiple times per day. We do not over crowd our fish and feed them an all natural premium product. With constant care, our fish enjoy these cold clean waters and are never exposed to herbicides, pesticides or harmful chemicals found in many of our lakes, rivers and oceans."
