The intensification of Penaeus monodon (black tiger shrimp) aquaculture has necessitated the development of sustainable, eco-friendly alternatives to synthetic chemotherapeutics to manage stress, disease, and sub-optimal feed utilization. This commercial-scale study evaluated the efficacy of dietary clove (Syzygium aromaticum) extract, a potent phytobiotic rich in eugenol, on the growth performance, feed conversion ratio (FCR), and survival of P. monodon. Shrimp were reared in 0.6-hectare ponds and fed a commercial basal diet top-coated with either 0 g/kg (Control) or 10 g/kg (1%) clove extract from day 50 to harvest (149-157 days of culture). Results indicated that 1% clove supplementation significantly enhanced growth metrics, yielding a final average body weight of 64.51 g and a daily growth rate of 0.411 g/day, compared to 52.63 g and 0.353 g/day in the control group. Furthermore, dietary clove dramatically improved feed utilization efficiency, lowering the FCR from 2.39 to 2.10. The survival rate also saw a substantial increase, reaching 95% in the clove-treated pond against 85% in the control, culminating in a total harvest biomass of 8,580 kg versus 6,262 kg. The observed enhancements in growth, FCR, and survival are attributed to the well-documented stress-mitigating, antimicrobial, and digestive-stimulating properties of clove bioactive compounds. Ultimately, this study demonstrates that dietary clove supplementation is a highly viable, natural performance enhancer capable of maximizing profitability and sustainability in commercial black tiger shrimp production.
