摘要 在 9.5℃ 条件下，对海洋桡足类桡足类 Acaria clausi 的鱼藤酮耐受性进行了实验测试，其中 0.01、0.05、0.10、0.50 和 1.00 ppm 鱼藤酮，成年雄性对鱼藤酮的耐受性显着低于桡足类和成年雌性。桡足类、雌性和雄性在 0.05 ppm 浓度下 16、18 和 4 小时后分别发生 50% 的死亡率。在 0.50 ppm 浓度下，所有阶段的总死亡率在两小时内发生。海洋和湖沼桡足类似乎具有相似的鱼藤酮耐受性。在鱼藤酮处理期间，海洋池塘或泻湖中的海洋桡足类种群将急剧减少。
Abstract Rotenone tolerance of the marine calanoid copepod Acartia clausi was tested experimentally at 0.01, 0.05, 0.10, 0.50, and 1.00 ppm rotenone at 9.5° C. Adult males had significantly lower tolerance to rotenone than copepodids and adult females. Fifty percent mortality occurred at 0.05 ppm after 16, 18, and 4 hours, for copepodids, females and males, respectively. At 0.50 ppm, total mortality of all stages occurred within two hours. Marine and limnetic copepods seem to have similar rotenone tolerance. Marine copepod populations will be drastically reduced in marine ponds or lagoons during rotenone treatments.
