This report describes the effects of swimming speed and seawater temperature on oxygen consumption of Takifugu rubripes, Pagrus major, and Girella punctata as a basic study for practical realization of an enclosed circulating flow type land culture. The following results were obtained. (1) The relationship between swimming speed and oxygen consumption shows two cases : that in which oxygen consumption increases gradually with swimming speed; and that in which oxygen consumption increases drastically with swimming speed. (2) Oxygen consumption increases with seawater temperature, except for Takifugu rubripes at 30℃. (3) The maximum swimming speeds, those at which maximum oxygen consumption is obtainable, for Takifugu rubripes, Pagrus major, and Girella punctata at 20℃ are, respectively, 2.5, 3.5 and 3 body lengths per second. (4) Results suggest that the breeding flow rate fit for flowing cultivation for Takifugu rubripes is 1-1.5 body lengths per second; that for Pagrus major and Girella punctata is 1.5 body lengths per second.
