为探明高锰酸钾、二氧化氯和大蒜素3种常用渔药对血鹦鹉鱼的毒性，进行了3种渔药对血鹦鹉鱼苗的急性毒性试验。结果表明：高锰酸钾对血鹦鹉鱼苗24 h，48h，72h和96h的半致死浓度（LC50）值分别为2．92 mg/L、2．59 mg/L、2．28 mg/L和1．83 mg/L，二氧化氯的LC50值分别为9．07mg/L、7．19 mg/L、6．20 mg/L和4．81 mg/L，大蒜素的LC50值分别为13．56 mg/L、7．08 mg/L、4．41 mg/L和3．51 mg/L。高锰酸钾、二氧化氯和大蒜素对血鹦鹉鱼苗的安全浓度分别为0．183 mg/L、0．481 mg/L和0．351 mg/L。血鹦鹉鱼苗对3种药物的敏感性为高锰酸钾＞大蒜素＞二氧化氯。

The acute toxicity of three kinds of aquacultural drugs,including potassium permanganate (KMnO4 ),chlorine dioxide(ClO2 )and allicin,on blood parrot fry were studied.The results showed that the 24 h,48 h,72 h and 96 h LC50 of potassium permanganate on blood parrot fry were respectively 2.92 mg/L,2.59 mg/L,2.28 mg/L and 1.83 mg/L,which of chlorine dioxide(ClO2 )were respectively 9.07 mg/L,7.19 mg/L,6.20 mg/L and 4.81 mg/L;and for allicin they were respectively 13.56 mg/L,7.08 mg/L,4.41 mg/L and 3.51 mg/L.The safe concentration of the three drugs was 0.183mg/L,0.481 mg/L and 0.351 mg/L,respectively.This suggested that susceptibility of blood parrot fry to the three drugs was as follows:potassium permanganate > allicin > chlorine dioxide(ClO2 ).
