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.
