Currently, the modern technologies of intensive aquaculture are made in recirculating systems which require the usage of certain high performance procedures for recirculated water treatment. Such a system includes the following essential subsystems: tanks for fish culture, mechanical filters, biological nitrification filter and denitrification filter. An actual issue in the modern aquaculture technology consists in the automatic drive of the recirculating systems. The main objective of such a monitoring and control system is to insure the quality parameters of recirculated water. This type of system needs an interdisciplinary approach, involving the knowledge of the dynamic properties of the physical, chemical and biological processes which take place in the recirculated water.

 

The main goal of this project is to obtain a mathematical model which describes the water quality evolution in an intensive recirculating aquaculture system and the development of a hierarchical intelligent control system of the aquaculture plant. Therefore, the obtained mathematical model must be adequate for the efficient automatic control of the system.

 

During the first year of progress the proposed objective of the project is the statement of certain mathematical models for the main elements of the recirculating aquaculture system: trickling biofilter and fish culture tanks. These models will be the basis of a global model for the intensive recirculating aquaculture system which will consider all embedded units of the plant. Finally, a hierarchical intelligent control system will be developed based on the global analytical model and on the experiments made on the plant.
