Abstract

Over the past years, the aquaculture has had a high rate of meat  production as human population has increased. However, with the growth of dense and semi-dense breeding systems, the increase in the prevalence of epidemics in aquatic animals, which reduces production, is increasing Oncorhynchus mykiss has been expanding rapidly in recent years. Along with such an expansion that calls for increased fish density per unit area, a variety of infectious diseases are spreading more rapidly in the spawning population, So that each year, it injures more than 10% of its annual output to the industry. Phytobiots, A group of natural stimuli that have been considered in aquaculture in the past two decades. These stimulants have a wide range of bioactive materials and have extensive activity, such as: stimulating intake of food, increasing digestive tract discharging, increasing immunity, anti-coccidiosis activity and anti-motility based on their permeability. Since rain bow trout due to marketable and well-culture in pond , the main fish concern of most farmers.in this review, we have studied phytobiotics and their effects on growth factors, bactericidal activity, immunity, blood indices and resistance to common pathogens of rain bow trout in the world.
