中文摘要 | 為提供給養殖業者施藥之參考,本試驗針對孔雀綠、甲烯藍、硫酸銅、福馬林、高錳酸鉀及美舒添等六種常用水產藥物,探討在20℃及30℃水溫下,其對銀鱸 (Bidyanus bidyanus) 之急性毒及半致死濃度 (LC50),並究明目前建議使用之濃度及藥浴時間是否適用於銀鱸。結果顯示,六種藥物對銀鱸96小時之LC50值,在20℃時,分別為孔雀綠0.25 ppm、甲烯藍22.75 ppm、硫酸銅2.12 ppm、福馬林112.81 ppm、高錳酸鉀2.13 ppm及美舒添2.91 ppm;在30℃時,則分別為孔雀綠0.21 ppm、甲烯藍5.80 ppm、硫酸銅1.07 ppm、福馬林84.71 ppm、高錳酸鉀1.97 ppm及美舒添0.92 ppm。由LC50值顯示毒性以孔雀綠最強,福馬林最低。毒性有隨水溫昇高而增強之趨勢,其中以甲烯藍、福馬林及美舒添最為明顯。另外,一般建議以美舒添100 ppm作1小時及高錳酸鉀3∼5 ppm作長時間藥浴,然而試驗結果發現。無論在20℃或30℃下,該等方法均不適用於銀鱸。而在30℃水中,以250 ppm福馬林藥浴的時間應短於1小時。 |
英文摘要 | The aim of this study was to investigate the median lethal concentration (LC50) of six chemotherapeutants on silver perch (Bidyanus bidyanus) under two controlled temperatures, 20 and 30 °C. The suitability of commonly recommended concentrations of agents was also examined for silver perch. When the water temperature was 20 °C with 96 h of exposure, the results showed that the LC50 values of malachite green, methylene blue, copper sulfate, formalin, potassium permanganate, and masoten were 0.25, 22.75, 2.12, 112.81, 2.13, and 2.91 ppm, respectively. When the temperature was 30 °C, their LC50 values were 0.21, 5.80, 1.07, 84.71, 1.97, and 0.92 ppm, respectively. This indicated that the agents were more toxic to the fish at 30 °C than at 20 °C. The relative toxicity of malachite green was stronger than the other agents, while formalin appeared to be less toxic than the others. The results also showed that the commonly recommended concentration of 100 ppm masoten for 1 h and 3~5 ppm potassium permanganate for long-term exposure are not suitable for silver perch. Moreover, the exposure duration of 250 ppm formalin for silver perch should be less than 1 h at 30 °C. |
