Top Imperial Surf Clam Fishing Countries

The Imperial surf clam (also known as the Arctic surf clam, *Mactromeris polynyma*) is a large, bivalve mollusk found in cold, sandy-bottomed waters of the North Atlantic, particularly off the coasts of Canada and northern Japan. Prized for its sweet flavor and vibrant red-tipped meat, it is a staple in sushi cuisine, especially as "hokkigai." The top countries harvesting Imperial surf clams are Canada and Japan, with Canada—specifically the province of Newfoundland and Labrador—being the world’s leading producer. The Canadian surf clam industry is highly regulated to ensure sustainability, using advanced dredging techniques and strict quotas. Japan also harvests surf clams, though its domestic supply is supplemented by significant imports from Canada to meet high demand. The United States has a smaller but notable surf clam fishery, mainly focused on the Atlantic surf clam (*Spisula solidissima*), a related species. The global surf clam industry is valued for its export potential, with Canada dominating the international market, particularly supplying Japan and other Asian countries.
