Abstract: Under conditions of temperatures (24±1)℃ and salinity 30, the subacute tolerance to pH and the acute toxixity to ammonia at different pH were carried out by using bay scallop \%Argopecten iradiaus\% larvae The results show: 1) the suitable pH for the larvae varies from 7 0～8 6; the most ones are 7 7～8 2; 2) at pH 7 63, 7 98, 8 34, and 8 74, the 96hLC\-\{50\} of total ammonia to the larvae are 20 01, 11 85, 3 32 mg/L and 0 55 mg/L, respectively; 3) when pH are higher than 8 34, pH increasing has doubling and coordinated affect on the toxicity of un-ion ammonia; 4) the toxicity of un-ion ammonia approximately is 90 times larger than that of ion ammonia
