6种常用渔药对福瑞鲤的急性毒性试验

Acute toxicity test of six drugs to FFRC strain common carp

在水温26.0～27.5℃的室内静水条件下,用平均体重(8.5±0.3)g/尾、平均体长(8.7±0.2)cm/尾的福瑞鲤(FFRC strain common carp,Cyprinus carpio)进行6种常用渔药的急性毒性试验。结果表明:硫酸铜、富氯、阿苯达唑、溴氯海因、敌百虫、灭孢灵的安全浓度分别为0.17、3.86、7.35、11.70、18.05、70.80 mg/L,6种渔药对福瑞鲤鱼种的毒性大小依次为:硫酸铜>富氯>阿苯达唑>溴氯海因>敌百虫>灭孢灵。富氯、溴氯海因、敌百虫和灭孢灵4种药物的安全浓度均显著高于目前生产使用的常用剂量,在福瑞鲤苗种培育和养殖过程中可以安全使用;硫酸铜的安全浓度显著低于生产使用的剂量,在养殖生产中应减少使用剂量;关于阿苯达唑药浴使用剂量的研究未见报道,试验结果可为今后其生产使用提供参考。

At water temperature of 26.0 to 27.5℃ and hydrostatic conditions in the room, the acute toxicity test of CuSQ4, high chloride, albendazole, BCDMH, trichlorfon and hundred of cyrtomium fortunei powder were conducted with FFRC strain common carp larvae, which average body length and average weight were （ 8.5 ± 0. 3 ） cm and （ 8.7 ± 0.2） g, respectivey. The results showed that the safety concentration of CuSO4, high chloride, albendazole, BCDMH, triehlorfon, hundred of cyrtomium fortunei powder were 0. 17, 3.86, 7.35, 11.70, 18.05, 70. 80 rag/L, respectively, the sensitivity in order of six kinds of drugs were CuSO4 〉 high chloride 〉 albendazole 〉 BCDMH 〉 trichlorfon 〉 hundred of cyrtomium fortunei powder. The safety concentration of high chloride, BCDMH, trichlorfon and hundred of cyrtomium fortunei powder were significantly higher than the production using dosage, so they could be used safely in cultivation of FFRC strain common carp. The safety concentration of CuSO4 was significantly lower than the production dosage, so the dosage should be reduced. The bath dosage of albendazole had not been reported in fisheries yet, so the test results could be used as reference in the future.
