Ayu
Plecoglossus altivelis
Adult ayu inhabit clear, fast-flowing rivers and streams in Japan, Korea, and parts of China. They graze algae from submerged rocks with comb-like teeth, while also taking small aquatic invertebrates when available. During the breeding season, males become strongly territorial and chase rival fish from productive feeding patches. This fish is prized for its distinctive sweet, melon-like scent, which gives it the name “sweetfish.”
