Fish ponds are widely used by man for food production. The
management of a fish pond affects the entire ecosystem, including
fish, nutrients, zooplankton, benthos, dissolved oxygen, micro
organisms etc. A high efficiency of fish breeding can be achieved
only with optimum values of the control parameters of the pond, like
the input of fertilizers, the aeration of the water in case of
oxygen depletion and the addition of artificial fodder.
A fish pond is an excellent case for the study of the
characteristics of food chains and ecosystems in general, because of
its relatively simple trophic structure. However, fish ponds can not
be studied in the biology curriculum for practical reasons (space
and time). The computer simulation program has been designed to
overcome these problems.
