Fujita, D.(Tokyo Univ. of Marine Science and Technology (Japan))
Recently, browsing by herbivorous fishes has been paid attention as a causative agent of seaweed/seagrass bed reduction in warm temperate waters of Japan. Although occurrence of these fishes has been known for 100 years, information on their ecology and resource levels has been quite limited. To evaluate the above phenomenon, roles and interactions of marine plants and herbivores were reviewed with special reference to the feeding ecology of herbivorous fishes in the world. The recent prevalence of destructive herbivorous fishes in Japan is very unique enough to reconsider coastal changes and over fishing rather than elevation of water temperature.
