The use of recirculating water supply systems for breeding freshwater fish is becoming widespread. It is important and urgent to ensure the energy autonomy of such systems. One of the methods of energy use of waste from fish farms is methane fer-mentation of sewage sludge from aqua culture enterprises. The purpose of the work is to assess the possibility of biogas production from sewage sludge in aquaculture to ensure partial energy autonomy of recirculating water supply systems. The article is devoted to the analysis of the current state of research on methane fermentation of sewage sludge in water recircu-lation systems. The analysis was performed on the basis of scientific publications in this direction and own research. An anal-ysis of technical solutions for artificial fish farming systems using biogas is provided. It has been established that sewage sludge from fish farms is a promising raw material for obtaining biogas, which makes it possible to achieve partial autonomy of recirculating water supply systems.
