OKUNO, Ryonosuke (Suma Aquarium of Kobe City, Kobe). Foods and behaviors of the rocky reef fishes on the coast of Asamushi, Mutsu Bay. Jap. J. Ecol. 15,183-188 (1965). During Sept. 1964,the behaviors and food relationships of fishes were investigated on the rocky coast of Asamushi, Matsu Bay. Twenty-five species were observed by underwater diving and 62 specimens belonging to 16 species were collected. The dominant species of this region were the following ten species : Girella punctata, Mylio macrocephalus, Opisthocentrus zonope, Pholis ornatus, Ditrema temmincki, Fugu niphobles, Sebastes inermis, Agrammus agrammus, Hexagrammos otakii, Pseudoblennius cottoides. Six among these ten species were also found along the rocky coast of Kasaoka Bay, Seto Inland Sea, by FUSE (1962). Food animals of these fishes were concentrated to the phytal animals, especially Gammaridae. Similar concentration had been found also on the rocky reefs of Kasaoka Bay in Autumn (FUSE, 1962). From these facts, it may be said that the fish communities of the rocky reefs of Asamushi and kasaoka fundamentally coincide with one another.
