There are various natural nutrients in fish ponds. In particular, phytoplanctons have high nutritional value not only for fish, but also for other hydrobiont organisms. Spirulina (Spirulina platensis), one of the blue-green algae, is a leader among phytoplankton in terms of its chemical composition. The presence of macroelements, microelements, vitamins, and biologically active substances in the body of this algae plays a major role in the growth and development of the fish body and the normal course of metabolic processes. Currently, several studies are being conducted around the world to study spirulina algae. This thesis briefly analyzes the distribution of spirulina algae in water bodies, their chemical composition, and their importance in increasing fish biomass.
