Analisis Ekologi–Ekonomi Pengelolaan Perikanan Berbasis Ekosistem Terumbu Karang (Studi Kasus Perairan Pulau Liwutongkidi, Kabupaten Buton,

Abstract

Coral reef one among the most productive and biologically diverse ecosystem on the earth. This thesis tries to explore ecological and economic value of coral reef at Liwutongkidi, Buton District. This study aims to identify: (1) Identified base substrate composition characteristic, fish community structure (2) To estimate coral reef ecosystem economical value and (3) To provide coral reef ecosystem management concept based on ecology-economic model on Liwutongkidi Islands marine conservation area. The percentage of live coral cover estimated around 13:01% - 72.50% on the island Siompu, Kadatua and Liwutongkidi, with the average 46.92% based on lifeform and can be classified as moderate category. Based on reef fish census was found that the major fish group was 3,899 individuals, indicator fish groups was 347 individuals, and the target fish group was 1625 individuals with a diversity between 2.71 - 4.72, which has mean they were all in medium till high category, the uniformity of reef fish between 0.69 - 0.92 which has mean a high category and stable communities. Economy Total (NET) from the direct benefits of coral fisheries resources utilization in coral Kapoa Village, Villages and Countryside Tongali, Waonu were respectively Rp. 11.579.106,17, Rp. 43.051.173,27 and Rp. 15.640.846,46 per month. System analysis and coral fisheries simulation result showed that the third scenario was more ideal in fish biomass simulation analysis on Liwutongkidi Islands conservation area and surrounds, there was a reciprocal relationship amongst catch efforts and fish biomass in a whole time.
