The experimental diets were isonitrogenous (300gkg−1) and isoenergetic (3.3Mcalkg−1), and were formulated to include 4 and 8% of the seaweed meal resulting in five experimental diets: NG4% and NG8% of the green seaweed and NK4% and NK8% of the brown seaweed, and a control diet without seaweed meal. Juvenile L. vannamei (1.42g) were stocked in 15 60L clean-water tanks at 70shrimpm−2 to evaluate growth. Shrimps of 4.0 and 9.0g were used for the digestibility trial. Survival in NK8% (93.3%) was the highest as compared to the control and the other diets. Apparent digestibility coefficients for dry matter and crude protein were over 80% in the seaweed meal treatments, and higher (P<0.05) than in the control diet. However, no significant differences (P>0.05) were found for final weight, feed conversion ratio, specific growth rate, protein efficiency ratio and individual consumption. This result indicates that an inclusion of 4 and 8% of brown and green meal in commercial shrimp feed supported adequate growth and survival of juvenile L. vannamei reared in RAS.
