Preserving the fish or aquatic population is an important thing to do, especially for fisheries management. On the other hand, there are so many things that could endanger the sustainability of the population. In order to maintain the population, the fisheries management should be able to handle it. One of obstacles that must be rid by the fisheries management is overfishing. Since that kind of overexploitation could harm the fish population, which is happened by reducing the fish stock to below acceptable level, the fisheries management need to use a proper concept in order to accomplish the mission of preservation.
