Introduction of various methods for the extraction of phytobiotics used in aquaculture

Phytobiotics are plant derivatives derived from leaves, roots, tubers or fruit plants, solid, dry or essential oils to improve nutrition for livestock and poultry farming. These plant derivatives are well-practiced in aquaculture, such as: stimulating food intake, increasing growth, increasing digestive tract discharges, increasing immunity, anti-coccidiosis and parasitic activity. Existing materials are from bioactive chemical groups such as alkaloids, phenols, flavonoids, terpenes and polysaccharides. Various methods are used to extract these effective ingredients. The choice of these methods in terms of plant species, solvent type, use or non-use of heat requires different techniques. In this paper, while reviewing the use of phytobiotics in aquaculture, the introduction of classical and modern techniques in this regard has been considered. Reports indicate that methods Modern due to the reduction of organic and synthetic chemicals and, saving time, efficiency and better quality of the extractive material are of interest to researchers. And given the need to take advantage of these valuable biomass in aquaculture, familiarity with these techniques in the future will be the key to achieving sustainable aquaculture.
