The existence and stability of interior equilibrium point are analyzed. The maximum profit problem is solved and optimal harvesting policy of present value of revenue is solved using Pontryagin???s maximum principle. From the analysis, there exists a critical value of the efforts that maximizes the profit and the present value of the revenue and the equilibrium point is also remain stable. Finally, numerical examples are given. ## Keywords - Predator - Predation - Stability (learning theory) - Stage (stratigraphy) - Apex predator - Control theory (sociology) - Ecology - Mathematics - Computer science - Biology - Artificial intelligence - Machine learning - Control (management) - Paleontology --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
