Abstract The influences of temperature, salinity, body mass and food intake on laboratory oxygen consumption rates (V O₂'s ) were quantified for goldfish (Carassius auratus) using a response-surface statistical method. V O₂'s of C. auratus were measured at 5 temperatures (10.0, 12.9, 17.0, 21.2, and 24.0 ^oC), salinities (280, 800, 1550, 2300, and 2800 mM each of Na⁺, K⁺, and Cl^-), and food intake rates (0, 41, 100, 159, and 200 mg dry every 2 d). Oxygen consumption rates were primarily influenced by water temperature, salinity, activity (lights on or off during O₂ consumption measurements) and body mass, and to a lesser extent by food intake rate. There were no interactive effects between mass and either temperature or salinity on routine energy metabolism, but significant interaction effect between temperature and salinity was observed.
