Benzalkonium Chloride、Benzethonium Chloride及Cetylpyridinium Chloride對草蝦、斑節蝦、熊蝦、紅尾蝦、砂蝦和淡水長腳大蝦等蝦苗藥浴之忍受度試驗

Abstract

This study aimed to investigate the TLm values of benzalkonium chloride, benzethonium chloride and cetylpyridinìum chloride for postlarvae of Penaeus monodon, P. japonicus, P. semisulcatus, P. penicillatus, Metapenaeus ensis and Macrobrachium rosenbergii dipped for 24 hours. The resu1ts were calculated using the Van der Waerden method. The TLm values of benzalkonium chloride for postlarvae of the prawns were 3.1, 3.3, 1.5, 1.6, 3.0 and 2.0 ppm, respectively. The TLm values of benzethonium chloride for postlarvae of the prawns were 10.0, 5.3, 3.2, 4.4, 9.0 and 6.0 ppm, respectively. The TLm values of cetylpyridinium chloride for postlarvae of the prawns were 0.8, 3.1, 1.0, 0.56, 2.1 and 0.13 ppm, respectively.
