Abstract:The model describes time-related changes in six variables: concentration of dissolved orthophosphate phosphorus P-PO4, phytoplankton, bacteria, detritus, nonpredatory zooplankton, and predatory zooplankton in the epilimnion of Lake Głębokie. The stability of the model was analysed, and it has been found that the variables show damped oscillations around equilibrium points. Results of numerical experiments are presented, simulating a cessation of fish farming in the lake, changes in the level and timing of phosphorus inflow to the epilimnion from deeper layers of the lake, and changes in temperature and light conditions. The results show that the inflow of phosphorus from deeper layers largely influences the values of the model variables.
