One of the major concerns of aquaculture lies in the generation of polluted effluent. The accumulation of feed residues and fish excreta elevates the concentration of dissolved inorganic nutrients, organic suspended solids and particulate organic matters. These excess nutrients, particularly nitrogen and phosphorus and other contaminants, are the main cause of eutrophication of the receiving water bodies. Microalgae may perform tertiary treatment due to their ability to incorporate inorganic nitrogen and phosphorous for growth and also have the capacity to remove heavy metals as well as some toxic organic compounds. In the present study the aquaculture wastewater was treated with microalgae is an efficient of removal of most of the nutrients and organic contaminants. https://www.biotech-asia.org/vol7no2/growth-and-nutrient-removal-rates-of-oscillatoria-acuminata-and-scenedesmus-armatus-in-aquaculture-wastewater-a-laboratory-scale-study/ Aquaculture; wastewater; micro algae; nutrien; removal
