11.2.3 Impacts of Disease
Disease was added to the model, and its results are shown in Figure 11.16. The
impact of the disease is arbitrarily chosen to demonstrate the impact. If the adult
density exceeded a limit (750
then the disease occurs, multi-
plying the natural mortality rate by a random increase between 1 and 3. With fishing
regulations in place, the adult density (total number of fish in this fishery) fluctuates
rather widely.
