摘　　要：作者采用动态实验法与静态实验法相结合的方法,研究了三门湾脊尾白虾(Exopalaemon carinicauda)、口虾蛄(Oratosquilla oratoria)和日本(Charybdis japonica)在不同季节的基础水温即驯化水温(8~29℃)和温升速率(0.5~15.0℃/h)下的热耐受能力。结果表明,驯化水温和温升速率对各实验动物的热耐受性均有显著影响。实验动物的热耐受性与驯化水温总体上呈显著正相关,而温升速率对热耐受性的影响具有物种特异性,并受驯化水温制约;在不同驯化水温下,各实验动物的热耐受性随温升速率增大呈不同变化趋势。各实验动物的24 h高起始致死温度受驯化水温的影响显著,随着驯化水温从8℃升高到29℃,脊尾白虾、日本和口虾蛄的24hUILT50分别从24.2、34.6、24.9℃显著增大到35.3、37.4和34.4℃。结合3种实验动物的最大临界温度分析,它们的热耐受能力依次为:日本>脊尾白虾>口虾蛄。研究结果可为探究三门湾水域潜在的热污染状况及其生态环境效应提供科学依据。This study aimed to investigate the effects of the acclimation temperature(8–29℃)and warming rate(0.5–15℃/h)on the thermal tolerance of three common marine crustaceans(Exopalaemon carinicauda,Charybdis japonica,and Oratosquilla oratoria)in Sanmen Bay,the East China Sea.We measured the critical thermal maximum(CTM)and 24-hour upper incipient lethal temperature(24-h UILT50)using the dynamic and static methods,respectively.The findings revealed that both the acclimation temperature and warming rate markedly affected the thermal tolerance of the experimental crustaceans.The thermal tolerance of each species increased with the increasing acclimation temperature.In addition,patterns how warming rate affected the CTM of the experimental crustaceans depended on the acclimation temperature.As the acclimation temperature increased from 8℃to 29℃,the 24-h UILT50 of E.carinicauda,C.japonica,and O.oratoria markedly increased from 24.2℃,34.6℃,and 24.9℃to 35.3℃,37.4℃,and 34.4℃,respectively.Overall,the thermal tolerance of the three experimental crustaceans revealed a ranking order of C.japonica>E.carinicauda>O.oratoria.
