【 摘 要 】

In this work we introduce the “Extensible Fish-tank Volume Model” that can reduce the complexity in the design and control of the Recirculating Aquaculture Systems. In the developed model we adjust the volume of a single fish-tank to the prescribed values of stocking density, by controlling the necessary volume in each time step. Having developed an advantageous feeding, water exchange and oxygen supply strategy, as well as considering a compromise scheduling for the fingerling input and product fish output, we divide the volume vs. time function into equidistant parts and calculate the average volumes for these parts. Comparing these average values with the volumes of available tanks, we can plan the appropriate grades. The elaborated method is a good example for a case, where computational modeling is used to simulate a “fictitious process model” that cannot be feasibly realized in the practice, but can simplify and accelerate the design and planning of real world processes by reducing the complexity.
