Abstrakt: This paper reports the approprite ranges of Mg2+, Ca2+and their ratio Mg2+/Ca2+in mixed seawater for rearing ofPenaeus japonicuslarvae. 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.
