Optimal Exploitation Of Life Reef Fish For Food (LRFF) In The Spermonde Islands Of South Sulawesi

Abstract: This research aimed to understand about the LRFF resources exploitation rate and its optimal used in the Spermonde Islands. The research was conducted in Spermonde Island of South Sulawesi. This research was used surplus production model with logistic growth function. Management model of LRFF resources based on maximum economic yield, maximum sustainable yield and open access regimes. Results showed that optimal biomass, optimal production and optimal effort at maximum economic yield were obtained at 5.120 ton, 1.047 ton and 284.792 trip. Sustainable biomass, productions and effort at maximum sustainable yield were 4.154 ton, 1.107 ton and 371.128 trip. Maximum biomass, productions and effort at open access were 1.933 ton, 790 ton and 569.584 trip. Economic rent obtained if applying regime of MEY was Rp 41.587.148.882, regime MSY was Rp 37.765.171.742 and regime open access was Rp.0. Exploitation of LRFF at Spermonde Island had indicated over fishing, because actual productions was greater than optimal productions. Therefore, on optimal management of LRFF fisheries resource is required to ensure long-term sustainability of the LRFF.
