| Abstrak (Bhs. Indonesia) | Penelitian tentang potensi lestari terhadap Ikan Nila di WGM. Penelitian potensi lestari Ikan Nila di WGM perlu dilakukan untuk memberikan informasi dasar pengelolaan sumberdaya Ikan Nila secara berkelanjutan. Tujuan penelitian ini adalah untuk mengetahui nilai MSY, fMSY, Y/R relatif dan E Ikan Nila di WGM. Penelitian ini dilakukan pada bulan Juni 2014 di WGM dengan metode survei. Data sekunder berupa data produksi dan upaya penangkapan Ikan Nila tahun 2009-2013 diperoleh dari DISNAKPERLA Wonogiri. Data primer berupa data pengukuran panjang (ketelitian 0,1 cm), berat dan tinggi (ketelitian 1 g) dari 486 ekor Ikan Nila. Data produksi dan upaya dianalisis dengan metode produksi surplus. Hubungan panjang-berat Ikan Nila dianalisis dengan model regresi linier sederhana. Analisis data estimasi parameter pertumbuhan menggunakan program FISAT II dengan mengikuti persamaan von Bertalanffy Lt=L∞(1-e-K(t-t0)). Mortalitas alami (M), mortalitas penangkapan (F) diduga dengan rumus empiris Pauly. Mortalitas total (Z), hasil per rekrut (Y/R) relatif dengan menggunakan model Beverton dan Holt. Nilai MSY model Schaefer 684,9221 ton/tahun, MSY model Fox 1852,6896 ton/tahun dan fMSY model Schaefer 1308 unit kapal, fMSY model Fox 6141 unit kapal. Pola pertumbuhan ikan nila adalah isometrik (b=3,013). Nilai estimasi parameter pertumbuhan (L∞)=33,7 cm, (K)=1,4 per tahun, (M)=0,2775 per tahun, (F)=1,5207 pertahun dan (Z)=1,7962. Laju eksploitasi (E)=0,8466 dan nilai Y/R=0,4527. Berdasarkan nilai MSY dan E, ikan Nila di WGM telah mengalami overfishing. |

| Abtrak (Bhs. Inggris) | Research on the sustainable potential of Tilapia (Oreochromis niloticus) in WGM. Research for sustainable Tilapia in WGM is needed to provide basic information resource management Tilapia sustainably. This research aims to determine the value of MSY, fMSY, Y/R relative and E of Tilapia in WGM. Research was held on June 2014 in WGMwith survey method. Secondary data (catch and effort of Tilapia in 2009-2013) was obtained from Animal Husbandry Fisheries and Marine Department regency. 486 samples of Tilapia were measured to the nearest 0,1 cm, and weighted to the nearest 1 g. Catch and effort data were analysed using surplus production model. Growth pattern was analysed using simple linear regretion model. Growth parameters estimation were analysed using FISAT II software by following the von Bertalanffy equation Lt=L∞(1-e-K(t-t0)). Natural mortality (M), fishing mortality (F) were analysed Pauly empirical model. Total mortality (Z), yield per recruit (Y/R) relative was analysed using Beverton and Holt model. The value of MSY of Schaefer model was 684,9221 tons/year, MSY of Fox model was 1852,6896 tons/year and fMSY of Schaefer model was 1308 ships, fMSY of Fox model was 6141 ships. Growth rate of Tilapia was categorized as isometric (b=3,013). The value of growth parameters estimation (L∞)=33,7 cm, (K)=1,4 per year, (M)=0,2775 per year, (F)=1,5207 per year and (Z)=1,7962. The value of eksploitation rate (E) and yield per recruit relative (Y/R) were 0,8466 and 0,4527 respectively. Based of the value MSY and E, Tilapia fishery in WGM has been overfishing. |
