Routine oxygen consumption rates of juvenile spot, Leiostomus xanthums , were measured over a range of temperatures, salinities and fish weights. As predicted, Q O 2 increased with temperature and decreased with body weight. However, Q O 2 decreased with decreasing salinity and did not show the expected minimum at isosmotic concentrations. The data are best described by the relationship: log 10 Q O 2 (mg O 2 g −1 h −1 ) = 0.129 log lo salinity (%0) + 1.604 log 10 temperature (°C)‐0.1401og 10 (g)‐2.767.
