Abstract Chemicals MgSO4 ∶CaCl2 ∶KCl∶H3B3O3 ∶KBr∶EDTA∶ lime stone were mixed at a ratio of 2000∶600∶72∶36∶24∶4∶1∶2 to make artificial sea water where Malaysian prawn Macrobrachium rosenbergii larvae were reared to research feasibility of Malaysian prawn larva rearing in artificial sea wa‐ter .The water quality detection proved that artificial sea water prepared by a ratio of Mg 2+ ,K+ and Ca2+=3∶1∶1 ,closed to natural sea water ,was non‐toxic .In the artificial sea water ,680 thousands of postla‐rvae was obtained with survival rate of 85% ,ecdysis rate of 16 .82% ,and specific grow th rate of 25 .34% /d ,higher than those in nature sea water .The findings indicate that artificial seawater can be used for Mal‐aysian praw n larva rearing .
