Figure 2. The main screen of the energy simulation model ANIPRO, giving access to
other parts of the model.
The main control strategy in the model is that at increasing outdoor temperatures the
ventilation is increased from minimum to maximum and that subsequently the water
suppletion to the system is increased to reach the desired water temperature. One of
the results of simulations with the model is that increasing ventilation through the
trickling filter by applying a larger fan is a very efficient option for temperature
control. Depending on local conditions, alternative techniques can be used.
Future developments
Currently, a pilot-system with a production capacity of 25 tonnes of eel is being built
according to the Blue Label principle. At the end of this year, the performance of this
system will be evaluated. Apart from specific design of systems, interesting work
remains to be done on design of buildings for farming fish.
The example of the development of eel farming in Western Europe clearly shows that
a main drive for system development is business opportunity for farming certain
species in closed systems.
