Abstract: Stress is a common factor among all animals and aquatic species suffer wide variety of stresses. Adaptogens are plant substances that have been known to mitigate stress in animals. Phytocee™ is a phytogenic feed additive known to alleviate stress in animals. In the current study, Phytocee™ was studied to know the survivability of the model fish, Zebra fish (Danio rerio) in an ammonia stress model. The test groups consisted of two groups; a) Normal control: 20 fishes received the normal feed without Phytocee™ b) Experimental group: 20 fishes received feed added with Phytocee™ @ 1Kg/ton (0.1%). The fishes were fed on these diets for 15 days. On day 16, the fishes were challenged with ammonium acetate at 40mM and were observed continuously and the mortality at every hour (time in hrs) was recorded till 100% mortality. Results showed that Phytocee™ afforded the protection against ammonia toxicity in Zebra fish. This study shows that Phytocee™, a herbal additive may offer antistress effect to aquatic species and improve their survival.
