摘要
热污染,由于热(核)电站和工矿企业等热废水排入江、湖等天然水域,使水温升高而影响水生物的正常生长,甚至造成生物死亡的严重后果。由热污染引起死鱼事件,在国内外早有记述。例如1975年日本沿海的50座核电站所排放出大量的热废水,曾导致大批鱼类死亡;
This experiment was intended to determine the effects of different temp(?)ratures on several freshwater fishes (black carp, grass carp, silver carp etc.) The ultimate upper lethal temperature was found to be 40.5—42℃ and the critical maximum temperature varied from 38 to 41.5℃ for fishes acclimatized at 28 to 32℃. An attempt was also made to determine the avoidance reaction and respiratory frequency of fishes in gradient temperatures. The results provided foundations for estimating the water temperature critelia of freshwater fish.
