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 18
From December to December 1998, the starvation experiment was conducted in the zoological laboratory of East China Normal University, Department of Zoology, East China Normal University, with the body weight of (1.42 ± 0.69) g at (20 ± 0. 5) ℃ , The effect of starvation on the metabolism of crab crabs was studied.The results showed that after 30 days of starvation, the oxygen consumption rate of juvenile crabs was reduced to 45.8% of the ingested state, and the CO2 emission rate was reduced to 5 4.1%; NH3 N excretion rate was reduced to 62.3% .Oxidation rate and CO2 emission rate, NH3N excretion rate varies greatly, oxygen consumption rate and CO2 emission reduction can be divided into four stages , While the decrease of NH3 N excretion rate can only be divided into three stages.At the same time, the standard metabolism of crabs was also affected by starvation, after starvation 30d, it decreased from 8.15Jg-1 h-1 to 3.97Jg- 1 h-1; in the starvation crab metabolism, the most fat consumption, followed by carbohydrates .Figure 2 Table 2 Reference 18
