| Abstract: | The use of meat and bone meal (MBM) was evaluated as a replacement for fish meal in a practical diet formulated to contain 41% protein and 8% lipid. Anchovy meal was replaced by 0%, 20%, 30%, 40%, 50%, 60% and 80% of MBM (diets 1–7) respectively. Healthy post larvae of Litopenaeus vannamei were reared in an indoor, semi‐closed recirculating system. Each dietary treatment was fed to triplicate groups of 40 shrimp per tank (260 L) arranged in a completely randomized design. The shrimp were hand‐fed to near‐satiation three times daily between 07:00 and 18:00 hours for 56 days. There were no significant differences (P>0.05) in growth performance among shrimp fed diets 1–6. However, shrimp fed diet 7 had significantly lower (P<0.05) growth than those fed diet 2 or diet 4. Survival ranged from 95% to 100% and did not significantly (P>0.05) differ. Feed conversion ratio (FCR) and carcass composition of the shrimp were not significantly (P>0.05) affected by dietary treatments. No significant differences (P>0.05) in protein efficiency ratio (PER) were found among shrimp fed diets 1‐6. However, shrimp fed diet 7 had significantly lower (P<0.05) PER than those fed diet 1 or diet 4. Results showed that up to 60% of fish meal protein can be replaced by MBM with no adverse effects on growth, survival, FCR, PER and body composition of L. vannamei. |
