A systematic review on the potentiality of algal meal as an aquaculture feed ingredient

Aquaculture is a vital source of protein and polyunsaturated fatty acids for humans. However, there are many obstacles to the sustain¬able growth of aquaculture, such as a lack of high-quality feed and feedstock and a decline in the quality and safety of aquatic goods. This paper investigates the potential of microalgae meal alternatives to fish meal to enhance the quality and health of fish species and shrimp. The microalgae and macroalgae play an important role in recent research for the production of diverse biopolymers. English databases such as PubMed, Google Scholar and Embase were queried from 2015 to 2024. We mined a total of 221 research documents, of which 11 articles were selected based on the inclusion and exclusion criteria. Both microalgae and algal products were found to positively impact the growth, fatty acid composition, polyunsaturated fatty acid concentration, and immunity of the different varieties of fish. However, algal feed dosage varied based on geographical location, algae and fish variety. Low dosages of algal feed were more efficient than high dosages. The study concludes that an algal feed mixture can partially replace fish meal in the aquaculture industry.
