Bioeconomic analysis of shortfin scads fish (decapterus spp) in the Flores Sea Waters of South Sulawesi Indonesia

Abstract

The bioeconomic approach is a combination of scientists with a biological approach and fish entrepreneurs in the field with an economic approach, widely used in various countries and is one of the references in the management of fisheries resources. This study aims to evaluate the stock of shortfin scads fish in the marine waters of Flores, South Sulawesi. The research conducted from April to September 2019 using a survey method for pelagic fishing gear in Flores Sea of South Sulawesi. Data collection was carried out through interviews using a questionnaire and direct measurement of caught fish. Research locations include the districts of Jeneponto, Bantaeng, Bulukumba and Selayar. Time series data on the number of fishing gear and catches for 10 years is calculated using the Microsoft excel program package. Result of this study showed that the actual production condition of the use of shortfins scads fish in the waters of the Flores Sea, South Sulawesi has exceeded the limits of the maximum sustainable potential and optimum sustainable yield. The optimal production is in OSY conditions of 31054.11 tons and the fishing effort of 102 purse seine units. To maintain the sustainability of elevated fisheries resources in the Flores Sea, required 59.5% reduction in fishing effort. The implication of the results of this study is the reduction of fishing units accompanied by the application of strict law enforcement so that the sustainability of short fin scads fish resources can be maintained.
