Miyazaki Prefecture creates artificial spawning grounds to protect native yamame trout

Efforts are underway in Miyazaki Prefecture's Komaru River to protect native yamame trout by creating artificial spawning grounds. Recent heavy rains and typhoons have damaged yamame habitats with sediment influx. Local fishery cooperatives and anglers are collaborating to restore spawning areas by carefully selecting and placing gravel. This initiative aims to support the natural reproduction of yamame, as research suggests stocking may be less effective. The creation of these artificial spawning grounds is a step towards ensuring the survival of the native yamame population.
