Environmental impacts of wastes from large-scale, intensive aquaculture are substantial and can lead to complex ecosystem changes. The application of known and new technologies can capture inorganic nitrogen from water and reduce organic enrichment of sediments. Biological methods, including Integrated Multi-trophic Aquaculture are now gaining interest for increasing in situ removal of nitrogen and other nutrients at sea cage sites. Several studies on biological nitrogen removal through nitrification, denitrification and anaerobic ammonium oxidation (anammox) have been reported and a number of bacterial groups active in this regard have been described. Nevertheless, additional efforts need to be focused on remediation of aquaculture wastewater and marine sediments. Conventional treatment systems have several disadvantages. Development of more efficient reactor systems and a holistic, integrated approach to waste treatment would allow more environmentally balanced aquaculture practices.
