摘　　要：于 1998年 10～ 12月在华东师范大学生物学系动物学实验室 ,对体重为 (1.42± 0 .6 9)g的幼蟹在 (2 0±0 .5 )℃温度条件下进行饥饿实验 ,研究了饥饿对中华绒螯蟹幼蟹代谢的影响 .结果表明 ,经过 30d的饥饿处理 ,幼蟹的耗氧率降低为摄食状态的 45 .8% ;CO2 排出率减小为摄食状态的 5 4.1% ;NH3 N排泄率减小为 6 2 .3% .耗氧率和CO2 排出率、NH3 N排泄率的变化差别较大 ,耗氧率和CO2 排出率的减小可分为 4个阶段 ,而NH3 N排泄率的减小仅可分 3个阶段 .与此同时 ,幼蟹的标准代谢水平同样受到饥饿的影响 ,饥饿 30d后 ,由 8.15Jg- 1 h- 1 减小为 3.97Jg- 1 h- 1 ;在饥饿幼蟹的代谢中 ,脂肪消耗最多 ,其次是碳水化合物 .图 2表 2参The effect of starvation on metabolism was studied on juvenile chinese mitten handed crab (Eriocheir sinensis) of (1.42±0.69)g at (20±0.5)℃ during Oct. -Dec., 1998.The results showed that oxygen consumption, CO 2 production and ammonia N excretion of the juvenile crab being starved for 30 days were 45.8 %, 54.1%, and 62.3%, respectively the course of oxygen consumption and CO 2 production reduction could be divided into four phases; and there were only three phases occurring during the course of ammonia N excretion reduction. Meanwhile, the standard metabolism of the starved crab reduced from 8.15 to 3.79 J g -1 h -1 also, and lipid was used as the first energy source in the course of starvation. Fig 2, Tab 2, Ref 18
