Feasibility of the use of Spirulina in aquaculture diets

The growth of aquaculture depends on protein sources that can reduce the pressure on fishmeal (FM), and Spirulina feed could be an option due to its high nutritional value. Studies on Spirulina as a food in diets of aquatic organisms have increased substantially in the past decade, but the fact that its use in commercial rations does not occur today indicates that there are still challenges that need to be overcome. This review attempts to compile most of the work carried out through today in aquaculture that uses Spirulina as an FM substitute and as a functional feed. The high cost of Spirulina can be compensated if it is used in small quantities because it can improve the health and growth of organisms, compensating for its high economic cost by reducing costs in other production areas.
