Abstract
We consider an optimal control problem for a nonlinear ´nutrient-phytoplankton-zooplankton-fish´ reaction- diffusion system, where the parameter for fish predation is treated as a multiplicative control variable. The model has implications for the biomanipulation of food-webs in eutrophic lakes to help improve water quality. We implement a semi-implicit (in time) finite element method with ´mass lumping´, and present the results of numerical experiments in two space dimensions.
