The Relationship between Blue-Girdled Angelfish (Pomacanthus Navarchus) Exploitation and Availability for a Sustainable Fishery in South Sulawesi

Blue-girdled angelfish, Pomacanthus navarchus is marine, expensive ornamental fish and is gaining popularity to be traded globally from which the social welfare increases. The study aims to (1) analyze exploitation status of fish regarding fish stock sustainability in South Sulawesi water, and (2) find out fish availability and demand in terms of exploitation level. Making the estimation of exploitation level, it applies optimum effort (Eopt) using FOX model; and making the prediction of fish demand and supply, it applies least square method. The findings indicate the exploitation status of fish in South Sulawesi water has been, in general, far above the total allowable catch (TAC), while the backward bending curve of fish availability indicates decreasing supply yet increasing fish price.
