Algae are important bioremediation agents and are being used in many wastewater facilities. Algae cultivation in aquaculture wastewater aims at removing the inorganic loads mainly, and producing biomass at the same time. Under photosynthetic conditions, algae growth also allows oxygen to be released, thus enhancing the auto-depuration potential of water. An algae-based recirculating aquaculture system has been developed, with different configurations for fresh and seawater farming. Such development can close the aquaculture loop by converting the biomass from water treatment into high-value fish feeds. This can allow for the symbiotic coupling of used water treatment to the production of fish feeds, which can significantly improve the profitability of aquaculture.
