Effective valorization of precision output of algaquaculture towards eco-sustainability and bioeconomy concomitant with biotechnological advances: An innovative concept

Both input resources and ecosystem stability are critical to the long-term viability and sustainability of the aquaculture business, which is booming while supporting global food security. Over the past few decades, technical advancements have been made to help achieve both economic and environmental goals. Among these, “algaquaculture,” which combines algae culture with aquaculture, is seen as a revolutionary concept with numerous advantages. The only difference between this system and aquaponics is that algae are used instead of leafy plants. In aquaponic systems, this integration is innovative because of algae’s superior ability to utilize waste-derived nutrients, such as nitrate, nitrite, and total ammonia nitrogen (TAN). An additional benefit of algae is that they promote growth, stimulate the immune system, and even enhance the color of fish. Some algae with human health benefits and biodiesel sources have a high market price, which can be used to compensate for an integrated aquaculture-based system’s higher economic value. While aquaculture waste bioremediation can greatly improve environmental sustainability, it is important to note that algae can play a significant part in bioremediation because of their ability to minimize environmental disruptions. This review aims to highlight the new concept of algaquaculture, functional role of algae in aquaculture, and biotechnological advancements for the bioeconomy to establish microalgae-based food production systems, including aquaculture, by citing the role and benefits of such an integrated algal-aquaculture system. For this reason, the review intends to disseminate an idea like this over the globe, focusing on how to preserve the sector in the coming years.
