The importance of using microbial feed additives in breeding ornamental fish

In line with the growth of the aquaculture industry, the reproduction and cultivation of ornamental fish has developed significantly due to its high economic importance. One of the most important challenges in the aquaculture industry is the improvement of formulated diets to improve the growth efficiency, nutrition and immunity of fish. In recent years, many efforts have been made in connection with nutritional strategies and optimization of feed compositions in different fish species. The use of microbial feed additives (probiotic, prebiotic and synbiotic) through different mechanisms can lead to increased growth, survival, immunity, improvement of reproductive functions and maintenance of water quality in breeding environments. Therefore, according to the successful results of using microbial feed additives in different species of fishes, the use of these additives is considered as an important strategy for better production of aquatic products in breeding systems and helps the sustainable development of the aquaculture industry.
