Materials and Methods: The experimental shrimp for this study were post-larvae 10 (PL 10) and 112,000 shrimps were reared in two ponds (9.6×40×1.2 m). One pond served as the control group and was fed with a basal diet, the other pond was considered as a PHFA group fed with a basal diet plus PhytoceeTM (2 kg/ton). The water quality parameters such as dissolved oxygen, temperature, pH, total ammonia nitrogen and nitrites were measured every day. Salinity was measured every 3 days. Litopenaeus vannamei shrimps were fed with respective diets for 104 days. Results: The total body weight (kg), FCR and survival rate (%) exhibited by control and PHFA groups were 1,108 & 1,145, 1.173 & 1.135 and 91.01 & 94.05, respectively. Results revealed that body weight (kg), FCR and survival rate (%) of L. vannamei were improved following the addition of PHFA at 2 kg/ton as compared to the control group. This could be due to the impact of individual ingredients which was already known to have adaptogenic, antioxidant and immunity-booster property. Conclusion: In conclusion, the addition of PHFA at the dose level of 2 kg/ton of feed could be recommended for the augmentation of the growth performance parameters of L. vannamei.]]>Rehman, S., A.H.
