Abstract: In order to test the effect of temperature on its metabolism,the parent female of Macrobrachium rosenbergii(De Man)were reared under a series of temperature, 20, 24, 28 and 32 ℃. Both respiration rate(RO)and excretion rate of ammonia-N(RN)increased with increasing temperature(T). Relationship between those parameters can be expressed as: RO = 0.1690 e0.1138T and RN = 0.7×10 - 4 e0.1981T, respectively. The energy consumption and the ratio of metabolic substrate were significant differences in different temperature. Energy consumption increased with increasing temperature, reaching 4 times higher at 32℃ than at 20℃. The ratio of metabolic substrate showed that protein was the first, followed by carbohydrate and lipid at 24 and 28℃, and ratio of protein further increased at 32℃. However, if temperature went down to 20℃, lipid became the dominant substrate instead of protein.
