The Ayu, or sweetfish (Plecoglossus altivelis), is a slender, migratory fish native to East Asia, renowned for its delicate, sweet flavor and cultural significance, especially in Japan. This species thrives in clean, fast-flowing rivers and coastal waters, and is highly prized both for commercial harvest and as a target of traditional recreational fishing methods such as "ayu-no-tomozuri" (friend fishing). Japan is by far the leading country in ayu fishing, with a well-developed industry that includes both wild capture and aquaculture, supporting local economies and culinary traditions. China and Korea also harvest ayu, though on a smaller scale compared to Japan, focusing more on regional consumption and local markets. The ayu fishing industry in these countries is closely tied to river health and water management, as the species is sensitive to pollution and habitat disruption.
