The effects of water temperature on oxygen consumption rate and ammonia excretion rate of Solenaia oleivora were studied in the laboratory. The results showed that, under controlled conditions and ambient temperatures 15-30℃, the relationship between oxygen consumption rate (O) [mg/h] and dry weight of soft tissue (W) [g] can be represented by an allometric equation O = aWb, while the relationship between ammonia excretion rate (N) [ μg/h] and dry weight of soft tissue (W) [ g] follows also an allometric equation N = cWb. It is indicated that both metabolic rates are correlated positively with water temperature. High temperature can reduce the level of protein metabolism. The linear regression among oxygen consumption rate (O), temperature (T) and dry weight of soft tissue (W) can be described by the equation O = -0.6513 + 0.0532T+ 0. 1073W, and for ammonia this relation is N = 32.1626- 1.0566T + 1.3222W, the multiple relation coefficient was 0.9642 and 0.8921, respectively.
