摘　　要：研究饥饿时间对不同体重的日本沼虾(Macrobrachium nipponense)能源物质利用和能量收支的影响.结果表明:饥饿初期日本沼虾主要依赖脂肪和碳水化合物供能,随着饥饿时间增加,开始部分消耗体内的蛋白质,最后完全依赖蛋白质作为能量来源,虾体营养组成和含量影响供能物质的利用.能量收支方程表明,在饥饿状态下日本沼虾代谢活动减弱,代谢能(R)逐渐降低,而排泄能(U)逐渐增加,体重对日本沼虾能量收支不产生影响.Under starvation conditions, the effects of starvation time and body mass on utilization of energy substance and energy budget of Macrobrachiurn nipponense were studied. The results showed that the shrimp relied mainly on body fat and carbohydrates as energy in the beginning of starvation. Along with the increase of starvation time, the protein began to be consumed partially. At last protein was the only source of the energy. Nutrition composition affected the utilization of energy substance. The energy budget equation of Macrobrachium nipponense under starvation conditions suggested that starvation decreased the metabolic activity of the shrimp, metabolic energy （R） gradually decreased, while the excretion （U） increased gradually. The body mass of shrimp had little effects on the energy budget.
