The ayu (Plecoglossus altivelis altivelis) or "sweetfish" is a summer delicacy in Japan and is caught in rivers throughout the country by anglers and by comorant fishermen.
The ayu, a member of the salmon family, has a one year life span and is also found in rivers in China and Korea. Usually grilled with salt over a charcoal fire, the fish is known for its deliciously "sweet" taste and is a traditional summer experience.
