摘要
This paper reports the approprite ranges of Mg 2+, Ca 2+ and their ratio Mg 2+/Ca 2+ in mixed seawater for rearing of Penaeus japonicus larvae. The ranges for the above three indices are 1150-1450 mg/L, 360-440 mg/L and 2.8-3.4, respectively. The proper salinity range of mixed seawater is 22.1-33.8 obtained by mixing estuarine water and concentrated seawater.
