Sustainable Operational Analysis of the Cultivation of Indonesian Thunnus albacares by Bioeconomic Approach

Abstract

This study aimed to describe the characteristics and cultivation conditions of Thunnus albacares in Pelabuhan Perikanan Pantai (PPP, shore-port fisheries) of Labuhan Lombok, East Lombok. Data was collected by a simple random sample using a questionnaire for 30 fishing boats. Primary data was collected by interview with respondents and field observation, while secondary data was obtained from records of PPP in Labuhan Lombok, BPS and DKP, East Lombok. Results showed that East Lombok has a high potential for T. albacares cultivation as well as eco-friendly fishery cultivation; this is practiced by local fishermen who commonly use traditional boats sized 4-7 GT complete with fishing utilities, including handline rods and trolling rods. From a biological aspect, there was open access to T. albaceros in 2006, followed by biological overfishing in 2007, and economic overfishing in 2005, 2008, 2009, 2010 and 2011. The maximum sustainable yield (MSY) reached 922,518.18 kg per year (MSY level 3,313 per year). The resource optimization of T. albaceros reached the peak of maximum economic yield (MEY) valued at IDR 24,693,982,361, with fish haul efforts from 2,063 annual trips yielding 791,270.90 kg of tuna per year.
