Innate immune response, immune gene expression, resistance to white spot syndrome virus as well as the growth performance were evaluated in Pacific white shrimp after feeding diet supplemented with fucoidan from tropical Sargassum crassifolium. Total hemocyte count, phagocytic activity, phagocytic index, superoxide dismutase activity, phenoloxidase activity, and total plasma protein significantly increased in shrimp treated by fucoidan, particularly at dose 750 mg kg-1 in days 4th of treatment. Shrimp proPO and lipopolysaccharide-β-glucan binding protein (LGBP) genes upregulation were highest at 6 and 12 days which maximum change reached at 2.4x105 and 1.1x103 fold, respectively. Whereas Toll and lectin upregulated highest at14 days of treatment (post-WSSV infection). In the separate trial, dietary 1,000 mg kg-1 fucoidan from S. crassifolium from 28 days significantly improved specific growth of shrimp 0.7% higher than control group. Subsequent result showed that 1,500 mg kg-1 fucoidan increased shrimp survival rate 20% higher than control group at2 days after challanged test. The shrimp resistance against WSSV also showed by decrease in copy number virus in shrimp tissue that treated with fucoidan coated diet. This current study supported the previous study in fucoidan from tropical Sargassum to enhance immunoprotection against WSSV and the first report as a growth promoter in L. vannamei.
