Top Stony Sea Urchin Fishing Countries

The stony sea urchin, often referred to in the context of fisheries as the "sea urchin" or specifically the "purple sea urchin" (Strongylocentrotus purpuratus) and related species, is a spiny marine invertebrate prized for its edible roe, known as "uni" in Japanese cuisine. The global sea urchin fishing industry is driven primarily by demand from East Asian markets, particularly Japan, where uni is a delicacy. The top stony sea urchin fishing countries include Japan, Chile, the United States (notably California and Alaska), Russia, and Canada. These countries harvest sea urchins from rocky coastal habitats using divers or specialized rakes, with strict regulations in place in many regions to prevent overfishing and ensure sustainability. Japan has a long tradition of sea urchin consumption and is both a major producer and importer, while Chile and the U.S. have developed significant export industries, supplying fresh and processed roe to global markets.
