摘　　要：实验在相同理化指标的海水环境下,以不同温度培养中国北方海域典型污损生物东方小藤壶(Chthamalus challengeri)成体,研究环境温度对藤壶生命表征的影响。实验结果表明,24.0℃以上藤壶死亡率随温度升高显著增加,至30.0℃已全部死亡;9.0℃时95%以上的藤壶进入休眠状态,至6.0℃全部休眠,由此得到了6.0℃的东方小藤壶休眠低温限和23℃的生命活动高温限。通过实验还发现了21.0℃为东方小藤壶及其幼体的最活跃温度,同时验证了东方小藤壶成体与幼体相进的温度适应性。The barnacles Chthamalus challengeri, a typical fouling organisms in northern China maritime space, were cuhivated under uniform environments with different temperature in order to find the effect of environmental temperature on the rates of survival, dormancy and activity. The results showed that the rate of survival diminished evidently at 24.0℃ and above, and all of the barnacles perished at 30.0℃. At 9.0℃ over 95% of the barnacles came into dormancy state,while all of them turned dormant at 6.0℃. The resuits show a bound from 6.0℃ to 23℃ in which the barnacle C. challengeri can live aptly. Meanwhile,it can be concluded from the experiment that 21.0℃ is the most fitting temperature for living to both barnacle C. challengeri and larval. Moreover,it can be found also that the effect of temperature on the barnacle and its larval is equal.
