摘　　要：研究溶解氧与亚硝酸盐对锈斑蟳(Charybdis feriatus)卵孵育时间的影响。结果表明,溶解氧与亚硝酸盐浓度变化均对锈斑蟳的卵孵育时间产生显著影响;海水溶解氧在2~12 mg/L时,锈斑蟳均可正常孵育,随着海水内溶解氧含量的提升,锈斑蟳卵孵育时间逐渐下降;亚硝酸盐浓度对锈斑蟳卵孵育持续时间产生显著影响,其浓度低于50 mg/L的条件适合锈斑蟳卵孵育,在亚硝酸盐浓度低于25 mg/L时,锈斑蟳卵孵育各阶段的持续时间较短。The effects of dissolved oxygen and nitrite on the incubation time of Charybdis feriatus egg were studied.The results showed that the concentration of dissolved oxygen and nitrite had a significant impact on the incubation time of Charybdis feriatus egg;when the dissolved oxygen content in seawater was within the range of 2~12 mg/L,Charybdis feriatus could be incubated normally.Within this range,as the dissolved oxygen content in seawater increased,the incubation time of Charybdis feriatus egg gradually decreased;nitrite concentration had a significant impact on the incubation duration of Charybdis feriatus egg.When the concentration was lower than 50 mg/L,it was suitable for the incubation of Charybdis feriatus egg.When the concentration of nitrite was lower than 25 mg/L,the incubation duration of Charybdis feriatus egg in each stage was shorter.
