研究了5 ~ 30℃驯化温度对鲤鱼尸僵过程的影响，以及0 ~ 10℃贮藏过程中ATP及相关化合物、糖原和乳酸的死后变化。驯化温度对达到最大刚性所需的时间和刚性强度都有很大的影响。随着驯化温度和储存温度之间差异的增加，尸僵发生得更快。0°c和5°c的差异在72小时达到最大，而10°c、20°c和30°c的差异分别在56、32和24小时达到最大。在30℃温差条件下，鲤鱼的最大严密性指数接近100%，而在0℃和5℃温差条件下，最大严密性指数仅低于60%。将鲤鱼从14°C转移到30°C后，花了4周时间将尸僵进程改变为典型的30°C模式。这些数据表明，在温度驯化过程中，蛋白质或脂质生物合成参与了鲤鱼尸僵模式的变化。在死后贮藏过程中，温热驯化的鲤鱼体内ATP、糖原减少和乳酸积累的变化速度快于冷驯化的鲤鱼。这些差异被认为是由暖、冷环境下鲤鱼ATP消耗速率的差异引起的。
Effects of the acclimation temperatures of carp between 5 and 30°C were examined on rigor-mortis progress and the postmortem changes of ATP and related compounds, glycogen, and lactate during storage at 0 and 10°C. The acclimation temperature gave large effects on both period required for reaching a maximal rigor and rigor strength. Rigor-mortis proceeded faster with increasing the difference between acclimation and storage temperatures. Rigor-mortis attained its maximum at 72h for 0 and 5°C-difference, while at 56, 32, and 24h for 10, 20, and 30°C-difference, respectively. For carp given 30°C temperature difference, maximal rigor index was almost 100%, while only below 60% for 0 and 5°C-difference. After transfer of carp to 30°C from 14°C, it took 4 weeks to change the rigor-mortis progress to a typical 30°C pattern. These data suggest that protein or lipid biosyntheses are involved in the changes of rigor-mortis patterns during temperature acclimation of carp. During the postmortem storage, changes of several compounds, i.e., ATP and glycogen de-crease and lactate accumulation, were faster for warm-acclimated carp than cold-acclimated one. These differences are considered to be derived from the differences of ATP consumption rates be-tween warm and cold-acclimated carp.
