White tanks had the highest survival rate, followed by transparency, black and blue tanks (P<0.05). The transparency tank had the best growth, followed by black tank, white and blue tanks (P<0.05). Daily food intakes of larvae with 5.1~10.0 mm in total length were 36.8~429.3 Artemia nauplii. When salinity was lowered 5 psu per week from 32 psu, all the larvae died under salinity condition 17 psu. In lowered 2 psu per 3 days, its all died at 16 psu.
