摘要
罗氏沼虾［Ｍａｃｒｏｂｒａｃｈｉｕｍｒｏｓｅｎｂｅｒｇｉ（ＤｅＭａｎ）］具有较高的经济价值，为当今世界上淡水虾类养殖的主要品种之一。由于我国没有天然的亲虾资源，人工育苗所需的亲虾靠养殖和人工越冬所得。因此研究亲虾的生理生态，可为提高人工繁殖技术的理论...
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.
