Dynamic model of fisheries management system and maritime highway program in Makassar Strait

Abstract

Abstract This research motivated by the existence of a sea highway (Tol Laut) program in the Makassar Strait that will build a number of ports. Port development must be supported by the fisheries management system that can utilize fish resources maximally and sustainably. Otherwise, it will fail and harm the country. The research aimed to create and simulate dynamic models of fisheries systems supported by the maritime highway program in the Makassar Strait. Data collection on environmental parameters, nutrients, phytoplankton and zooplankton abundance, catches, and gastric contents analysis has been conducted. The dynamic models that are built consist of 4 sub-models, namely: (1) Plankton Productivity submodel; (2) Pelagic Fisheries sub-model; (3) Demersal Fisheries sub-model and (4) Economy and Maritime Highway sub-model. The simulated scenario is different capture quota in planktivores, omnivore, carnivore, and demersal fishes. The result of simulation by using a dynamic model revealed that there are differences in fish population dynamics based on the catch rate and the provision of port facilities. The development of the Maritim highway program that synergizes with the determination of catching quotas can increase the revenue of around 5 to 28 billion rupiahs per month per district during 120 months in 11 districts/cities on the coast of Makassar Strait.
