Stress management in zebrafish is a significant area of research, and probiotics may aid in alleviating stress. Probiotics, which are live bacteria that can make you healthier if you take enough of them, have largely been studied in the gut microbiota and immune systems of animals. But more and more people are using them on zebrafish, which have a very good way of dealing with stress. Zebrafish are excellent models for investigating stress-induced behaviours and physiological alterations resulting from overcrowding, temperature fluctuations, and chemical exposure. Probiotics may regulate stress-related pathways and neurotransmitter systems in zebrafish, mitigating behavioural and physiological symptoms associated with stress. The main results suggest that probiotics can change the makeup of the gut microbiota and improve intestinal health, which can help with stress-related reactions. The impact of probiotics on zebrafish physiology and behaviour elucidates stress-related disorders and presents potential therapies for humans and other organisms. This abstract examines research in this emerging field and underscores the necessity of comprehending the intricate interplay of probiotics, stress, and the welfare of aquatic organisms
