摘要
根据天津大港电厂扩建工程的需要,对黑龙江河兰蛤存活的各项温度指标进行了试验。黑龙江河兰蛤起始致死温度是随驯化温度的变化而改变。最高起始致死湿度为37.1℃,生长的周平均最高温度为29℃、短期暴露最高温度是35.45℃。对大港电厂冷却水体对兰蛤有否危害进行了初步评价。
According to the need of the second engineering of Da-gang power plant, we obtained several maximum temperature values of the clam.The incipient lethal temperature are shiftedupward by acclimation to warmer temperature.The ultimate upper incipient lethal temparature is 37.1℃. The maximum weekly average temperature of growth is 29℃. The shorttime exposure to extreme temperature is 35.45℃.Objectly evaluated the damages of the heated waters of Da-gang power plant on the clam.
