Abstract
This paper aims to assess the existing knowledge on the use and effects of phytobiotics in fish farming, as well as their potential for broader application in aquaculture. With the rising demand for fish, there has been a noticeable decline in fish production in recent years, which could be a driving factor behind the increasing interest in using phytobiotics in this field. The main factor contributing to the decrease in fish production is the widespread occurrence of diseases caused by various pathogens. Enhancing disease resistance, feed efficiency, and growth performance in farmed fish is crucial for the different sectors within this industry. In commercial aquaculture, reducing production costs is a priority, especially given the high expenses associated with antibiotics for disease prevention and treatment, as well as hormones for growth enhancement. This has driven research into new alternatives, leading to the development of the concept of functional additives in aquaculture, which includes “phytobiotics.” Studies have demonstrated that incorporating phytobiotics into fish diets can improve the innate immune response against bacterial infections, particularly Aeromonas hydrophila, across various fish species. These compounds primarily boost the activity of phagocytic cells, enhance their bactericidal properties, stimulate natural killer cells, complement activity, lymphocyte proliferation, lysozyme production, and antibody responses in fish. In conclusion, further research is required to determine the optimal use of different phytobiotics, with a focus on timing, dosage, and methods of administration.

The main cause of the drop in fish production is the widespread presence of diseases brought on by various pathogens.
