Abstract：Acute toxicity of bromo-geraminum to zoea (Z) and megalopa (M ) in Chinese tiger crab Orithy-ia sinica was studied at water temperature of 25-26 ℃ and a salinity of 22 .It turned out that the endur-ance capacity of Chinese tiger crab larvae to bromo-geraminum was changed over time .The LC50 value(me-dium lethal concentration) in 36 h was ranged as M >Z3 > Z2 >Z1 ,while in 48 h M>Z2 > Z3 > Z1 .The LC50 of bromo-geraminum in 48 h was found to be 22 .934 mg/L in Z3 ,32 .972 mg/L in Z2 ,28 .919 mg/L in Z1 ,and 48 .837 mg/L in M ,with safe concentration of 0 .8982 ,1 .8009 ,0 .9162 ,and 3 .6367 mg/L from Z1 to M in turn .It is suggested that the safe concentration be 0 .8982 mg/L during larva breeding of Chi-nese tiger crab .
