The oxygen consumption rate of reared blacktip grouper, Epinephelus fasciatus was investigated under six different water temperature conditions (15.0, 17.5, 20.0, 22.5, 25.0 and 27.5°C) and three body sizes (16, 97 and 645 g in mean body weight) from young to adult. In each body size, the oxygen consumption rate per individual (R: ml/ind./h) increased with an increase in water temperature (T: °C) between 15.0 and 27.5°C following the equation R=AT⋅B, where A and B are constants. In each temperature, the oxygen consumption rate increased with an increase in body weight (W: g), following the equation R=K⋅ Wb, where K and b are constants. To unite the two equations, the quantitative relationship of oxygen consumption rate as it related to body weight and temperature between 15.0 and 27.5°C was expressed by the equation R=M⋅ Wb⋅AT, where M, b and A are constants. The estimated values of these three constants for blacktip grouper were 0.0256, 0.773 and 1.083, respectively.
