<p>In the present study, the effects of dietary supplementation of low molecular weight sodium alginate on growth, body composition, anti-oxidant enzymes, digestive enzymes, and immune response in yellowfin sea bream juvenile (<italic>Acanthopagrus latus</italic>) were investigated.

The results showed that the final weight, weight gain, specific growth rate, condition factor, feed conversion, and protein efficiency ratios did not reveal a significant improvement compared to the control treatment (P>0.05). The obtained results indicated that dietary sodium alginate did not affect body composition (P>0.05). The activity of antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) in the groups fed on 0.5 and 1% sodium alginate showed a significant increase (P&lt;0.05) compared to the control group.

The digestive enzymes increased significantly (P&lt;0.05) by supplementation of sodium alginate, compared to the control group.
