为确定二氧化氯对海湾扇贝(Argopecten irradians)亲贝、幼虫和稚贝的安全用量范围，本实验研究海湾扇贝亲贝、D型幼虫、眼点幼虫和稚贝对不同浓度二氧化氯的耐受性。按照亲贝、D型幼虫、眼点幼虫和稚贝的先后顺序进行4个独立实验，每实验设6个不同的二氧化氯浓度，每浓度设三个重复，每实验持续时间为24 h，分别在12 h和24 h测定二氧化氯对亲贝和幼虫死亡率的影响。结果表明，海湾扇贝亲贝、D型幼虫、眼点幼虫和稚贝对二氧化氯均具有较强的耐受性，其安全浓度分别为20 mg/L、5 mg/L、10 mg/L和10 mg/L。

Four experiments were respectively conducted to determine the tolerance of broodstock, larvae and juvenile of bay scallop (Argopecten irradians) to different concentrations of chlorine dioxide for safe use in disease prevention and cure. Each experiment had six treatments with three repetitions according to the concentrations of chlorine dioxide. Each experiment last out for 24h, and data of mortality rate were respectively determined at 12h and 24h. The results showed that the safe concentrations of chlorine dioxide for broodstock, D larva, eyebot larva and juvenile were respectively 20 mg/L, 5 mg/L, 10 mg/L and 10 mg/L.
