Relationships between the riverside vegetation and the health of a subspecies of Japanese common char, Salvelinus leucomaenis imbrius (‘Gogi’) were studied in the Chugoku Mountains. The densities of riverside vegetation comprising deciduous broad-leaf and evergreen coniferous trees, food environments comprising benthic and flowing aquatic animals and falling terrestrial animals, and the relative liver weight of char were examined. It is suggested that a high density of deciduous broad-leaf trees provides a good food environment, resulting in sound health of Gogi char. |
