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（T，℃）和体重（W．g）影响，它们的关系式为：C＝26.7W－0.389e0.16T;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。
The studies on the energy budget of M. nipponcnse collected from Shanghaiwere conducted during Mar. and May, 1993. The experimental results showed that(1)energy consumption [C,J/(g·d)]was affected by water temperature (T,℃) andbody weight (W, g); the relationship was: C =26.7W-0.389e0.106T; (2)during the pe-riod of interxnolting, the mean proportions of consumed energy allocated to faecalproduction, growth, excretion and metabolism were 6.2 gh, 37.0 %, 1.4% and 55.4 %,respectively; (3)the proportion of the energy allocated to growth reduced in respon-se to the increase of water temperature, and that to metabolism increased in respon-se to the increase of water temperature.
