Purpose. Conduct a comprehensive analysis of scientific literature to summarize data on innovative approaches to water purification in recirculating aquaculture systems (RAS). Consider methods of controlling the quality of the aquatic environment, modern systems for monitoring water parameters, as well as advanced technologies for its purification and preparation, which contribute to increasing the efficiency of such systems functioning.

Findings. A review of current scientific publications related to modern approaches to water purification in aquaculture, which directly contribute to increasing the efficiency of commercial product production in recirculating aquaculture systems, is presented. Information from literary sources on the most common methods of monitoring and controlling the quality of the aquatic environment is summarized. The main types of biofilters are described in detail and the principles of their functioning are revealed. Special attention is paid to innovative methods of water treatment, in particular electrooxidation and electrocoagulation. The prospects of integrating the latest environmentally friendly solutions, focused on preserving the natural environment, into water treatment processes for RAS were noted.

Practical Value. This review will be useful for scientists, graduate students, students, government officials, and private entrepreneurs specializing in the cultivation of commercial aquaculture products in recirculating aquaculture systems.

Keywords: recirculating aquaculture systems, water purification, biofiltration, bioreactors, electrooxidation, electrocoagulation.
