Aquatic plants are potent antioxidants that might promote health and reduced oxidative damage induced by a variety of ecological pollutants in aquatic organisms. The privileges of dietary Thalassodendron Ciliatum intervention were assessed in Nile tilapia (Oreochromis niloticus) pre- and post-acute ammonia exposure. A total of 160 healthy male juveniles (weighing 12.4 ± 0.01 g) were allocated randomly into four equal groups (each group containing four replicates). The feeding trial lasted for 8 weeks; the first group served as a control (fed a basal diet), while, the remaining three groups were fed diets supplemented with 1, 3 or 5% T. ciliatum extract (TCE1%, TCE3% and TCE5% respectively). By the end of the feeding trial, all fish groups had been exposed to a 6-h acute ammonia exposure with 5 mg TAN per Liter, relying on pH level and water temperature degree. Prior to the ammonia toxicity test, all performance data indicated that a low dosage of TCE (1 or 3%) resulted in significant improvements (P > 0.01 or 0.001). Meanwhile, fish assigned TCE5%-rich diets reported the highest levels of crude protein and lowest lipid percentages when compared to the control group. Furthermore, fish administered a high dose of TCE had significantly (P
