| 摘 要： | 研究了鳡鱼苗对氯氰菊酯和阿维菌素的耐受力。结果表明，2日龄的鳡鱼苗在0．02mL／m^3和0．03mL／m^3 2种浓度的氯氰菊酯药液中，4～5min狂游打转，40min开始死亡，分别在1h40min和1h30min全部死亡。2日龄鲢鱼苗在上述浓度的药液中，9h17min开始死亡，24h死亡率分别为8％和56％；在0．375mL／m^3和0．0525mL／m^3 2种浓度的阿维菌素药液中，2日龄鳃鱼苗1h开始死亡，7h死亡率100％。鳡鱼苗对氯氰菊酯和阿维菌素的耐受力极差，不能用这2种渔药防治鳡鱼苗种疾病。

| Abstract: | It was studied that endurance of two new fishery drugs which are cypermethrin and avermetin to fries of Elopichthys bambusa. The results showed that： the 2 days old fries of E. bambusa were liberated in cypermethrin solution at two concentrations of 0.02 ml/m3 and 0.03 ml/m3, they swam and revolved madly after 5 min, they began to die after 40 min, all of them were died respectively after 1 h 40 rain and 1 h 30 rain. In the same eypermethrin solution, the 2 days old fries of Hypophthalmichthys molitrix began to die after 9 h, their rates of death were 8% and 56% respectively after 24 h. In the avermetin solution at two concentrations of 0.375 ml/m^3 and 0.0525 ml/m^3 , 2 days old fries of E. bambusa began to die after 1 h, their rate of death was 100% after 7 h. The endurance of cypermethrin and avermetin to fries of E. bambusa was inferiorest, therefore, the two drugs could not be applied in disease prevention and control of fry and fingerling of E. bambusa. |
