The effect of dietary microencapsulated diet (MED), artificial diet (ATD; approximately 28% protein) and Artemia shell-free (ART) on growth performance, survival rate, diet digestibility, protein synthesis capacity, enzyme activities of the larvae shrimp were investigated. The experiment was conducted in 3 treatments with 5 replicates. The 1 day post hatched (1 dph) shrimp were then fed twice daily with experimental diets for 60 days. The results of this study indicated that the larvae fed with the MED showed a higher (P<0.05) growth performance in term of total weight, specific growth rate, average daily gain and survival rate than the larvae fed with ART and ATD. Concerning the experimental diet digestibility, MEDwas reported to have higher protein and carbohydrate digestibility than ART and ATD in both the 15 and 60 days larvae (15 and 16 dph) (P<0.05). Regarding, protein synthesis capacity, muscle RNA concentration in the shrimps fed with MED (16.33±1.15 µg mg-1 muscle) was much higher than the other treatments (P< 0.05). Similarly, the shrimps fed with MED over 60 days had the highest protein synthesis capacity (RNA/protein ratio) (P< 0.05). However, the results of muscle protein concentration showed no difference between the treatments. (P>0.05). Enzyme activities were also focused on, the results indicated that the protease, amylase and lipase activity of the larvae fed with the microencapsulated diet was much higher than the other experimental diets (P< 0.05).
