摘　　要：研究了戊二醛、二溴海因、蛋氨酸碘和次氯酸钙等4种消毒剂对大珠母贝(Pinctada maxima)幼贝的急性毒性,结果表明,毒性大小依次为次氯酸钙>二溴海因>蛋氨酸碘>戊二醛,24 h半致死质量浓度(LC50)分别为13.05、27.49、53.20、67.36 mg/L,48 h LC50分别为10.15、9.35、29.27、35.58 mg/L,安全浓度SC分别为1.86、0.32、2.66、7.52 mg/L。分析认为,由于戊二醛毒性相对较小,且在其安全浓度以下可获得较好的消毒效果,因此在大珠母贝幼贝的养殖过程中,推荐使用戊二醛作为常用消毒剂,二溴海因和蛋氨酸碘应谨慎使用,次氯酸钙不推荐使用。The acute toxicity of glutaraldehyde,dibromohydantoin,methionine iodine and calcium hypochlorite to juvenile Pinctada maxima was studied.The results showed that the order of toxicity was calcium hypochlorite> dibromohydantoin> methionine iodine> glutaraldehyde,and the median lethal concentrations(LC50) of above disinfectants were 13.05 mg/L,27.49 mg/L,53.20 mg/L and 67.36 mg/L respectively in 24 h,and the LC_(50) were 10.15 mg/L,9.35 mg/L,29.27 mg/L and 35.58 mg/L respectively in 48 h;and their SC(safe concentration) were 1.86 mg/L,0.32 mg/L,2.66 mg/L and 7.52 mg/L respectively.We can use glutaraldehyde to disinfect P.maxima under safe concentration,but should not use calcium hypochlorite,and can use dibromohydantoin and methionine iodine carefully.
