The Republic of Bulgaria has adopted the basic principles of water management policy laid down in Directive 2000/60/EC of the European Parliament. The main focus of this policy is to meet the needs of water in the quantity and quality necessary for the needs of economic sectors and especially for the manufacture of agricultural products. The study indicates that application of the integrated water resource management is an approach that achieves not only the environmental objectiveswith regard to the aquatic ecosystems, but also a coordinated managementof waters, land and the vital ecosystems. The condition of water management in Bulgaria was examined at a nationaland basin level. It was found that the river basins determined in the Water Act do not follow the administrative and territorial division of the country. The management of aquaculture systems is carried out on technological and basin principle in accordance with the terms and conditions of the permits for water use and use of water units for different economic activities.
