摘要:

于1993年3－5月对采自上海市的日本沼虾的能量收支进行研究。结果表明，其日摄入能量[C，J/(g?d)]主要受水温（Ti>，℃）和体重（W, g）影响，它们的关系式为：C＝26.7W^-0.389e^0.16T;在蜕壳间期，其援食摇蚊幼虫时摄入能量有6.2％以粪便排掉，37.0％被用于生长，1.4％作为氮和尿素被排泄，其余55.4％被呼吸代谢；随水温提高其摄入能量中用于生长的比例减小，用于呼吸的比例增加。

Abstract:

The studies on the energy budget of M. nipponense collected from Shanghai were conducted during Mar. and May, 1993. The experimental results showed that (l) energy consumption [C, J/(g?d)]was affected by water temperature (T,°C) and body weight (W, g); the relationship was: C＝26.7W^-0.389e^0.16T; (2) during the period of intermolting, the mean proportions of consumed energy allocated to faecal production, growth, excretion and metabolism were 6.2%, 37.0%, 1.4% and 55.4%, respectively; (3) the proportion of the energy allocated to growth reduced in response to the increase of water temperature, and that to metabolism increased in response to the increase of water temperature.
