A computer model of a fertilized warm‐water aquaculture pond has been developed. The model is intended to represent the pond ecosystem and its response to external stimuli. The major physical, chemical, and biological processes and parameters are included in the model. A total of 22 state variables are used in the model (dissolved oxygen, ammonia, alkalinity, phytoplankton, zooplankton, fish, etc.). The model is fonnulated as a system of mass balance equations. The differential equations include stimulatory and inhibitory effects of environmental parameters on processes taking place in the pond. The equations may be solved for the entire growth period and diurnal as well as seasonal fluctuations may be identified.
