Complementary feedstuff extract from Laminaria digitata and Ascophylum nodosum that containing 1% alginic acids as shrimps stimulating of immune system for control of WSSV is used in this study. The test shrimps Litopenaeus vannamei in larvae stage (Z1-PL1), post larvae stage (PL1-PL10) and juvenile (from 30th day to 40th day) fed by complimentary feedstuff comprised control group. The other condition in test and control group was the same manner. Both groups after 40 days exposed to WSSV by oral inoculation. The clinical sign and mortality recorded for 10 days. The results showed the survival rate of exposed group was higher than the control group and it was significant (p<0/05). The result also show the mortality observed in exposed group 48 hours later than the control group. This study can led us to new methods for control of White spot disease.Pages
