| Abstract: | Routine oxygen consumption rates of juvenile spot, Leiostomus xanthums , were measured over a range of temperatures, salinities and fish weights. As predicted, Q O2 increased with temperature and decreased with body weight. However, Q O2 decreased with decreasing salinity and did not show the expected minimum at isosmotic concentrations. The data are best described by the relationship: log10 Q O2 (mg O2 g?1 h?1) = 0.129 loglo salinity (%0) + 1.604 log10 temperature (°C)-0.1401og10(g)-2.767. |
