Metabolism based on laboratory studies of young winter flounder acclimated to estuarinclike conditions show that rates of oxygen uptake (ml O 2 hr/g), as a function in increasing temperature, do not differ significantly between salinities of 10 and 20 ‰. There is, however, a 40–50% decrease in the quantities of oxygen consumed by fish subjected to salinities of 10 and 20 ‰. Metabolic rates do not differ between fish sizes used (within the I+ group: 100–135 mm total length and 140–175 mm total length). Slopes in the equation, log metabolism = log a + b log weight, for temperatures of 24 C, 20 C, and 16 C (30 ‰ salinity) exceed unity.
