Abstract:	The investigated combined intensive-extensive system (IES) as a production system operated in a close interaction of the intensive and extensive production units. The key element of the proper operation was the treatment capacity of the extensive unit; hence the investigations were focused on the periphyton application on the nutrient utilisation and water quality of the production system. Results proved that combination of intensive aquaculture with extensive fishponds enhances the nutrient utilisation efficiency and fish production in IES. The combined fish production resulted in higher protein utilisation by 26%; even this ratio can be increased by 40% with periphyton application.
