摘　　要：[目的]研究氟苯尼考对四角蛤蜊稚贝的急性毒性作用。[方法]采用静水水生生物测试方法,分别在24、48、72和96 h观察四角蛤蜊稚贝的死亡数,并计算出氟苯尼考的安全质量浓度。[结果]氟苯尼考在24、48、72和96 h的半致死浓度分别为2 930.65、1 585.86、1 415.32和948.64 mg/L,氟苯尼考对四角蛤蜊稚贝的安全浓度为139.31 mg/L。[结论]该研究为四角蛤蜊人工苗种繁育过程中的合理用药提供了理论依据。[Objective] The research aimed to study the acute toxicity of florfenicol to juvenile Mactra veneriformis.[Method] The dead number of juvenile M.veneriformis after 24,48,72 and 96 hours were observed by using hydrostatic aquatic organisms testing method.And the safe quality concentration of florfenicol was calculated.[Result] The half lethal concentration of florfenical after 24,48,72 and 96 hours were 2 930.65,1 585.86,1 415.32 and 948.64 mg/L respectively.The safe concentration of florfenicol to juvenile M.veneriformis was 139.31 mg/L.[Conclusion] The research provided theoretical basis for rational drug application in artificial fingerling breeding of M.veneriformis.
