Abstract. The study was conducted onApril to October 2013 in marine protected areas of Weh Island. The samplings were done at10 siteswhere 6 sitesare situatedinside of conservation areas, while 4 sites are situated outside of conservation areas. The purpose ofthis study was to evaluate coral covers andreef fish composition. Point intersept transect(PIT), underwater visual census (UVC) and fish catches were used to examine coral covers, abudance and biomass of reef fish. The results showed that average of coral covers, abudance and biomass of target fishes inside conservation were 54%, 1,662 ind/ha and 408.78 kh/ha, respectively, while than outside conservation was 33.05%, 1,058 ind/ha and 307.77 kg/ha, respectively. Total of reef fish species and the catch were increased from previous years, for example there are 60 species in 2010 and it was increased to 83 species in 2013. In addition the fishermen catches were increased slightly from 3.03 kg/trip in 2008 to 3.6 kg/trip in 2013. It is concluded that the coral condition and reef fish composition in the conservation are much better compared to outside of conservation areas.Keywords : Marine protect area; reef fish; Weh Island Abstrak. Penelitian ini dilakukan pada April sampai Oktober 2013 di Kawasan Konservasi Perairan Pesisir Timur Pulau Weh yang terdiri dari 10 stasiun dimana 6 stasiun berada didalam kawasan konservasi dan 4 stasiun diluar kawasan konservasi.Penelitian ini bertujuan untuk menilai persentase tutupan karang dan komposisi ikan karang. Sampling menggunakan transek titik dan underwater visual sensus (UVC) dan hasil tangkapan.Hasil penelitian menunjukkan bahwa rata-rata kondisi tutupan karang, kelimpahan dan biomassa ikan target dikawasan konservasi yaitu 54%, 1.662 ind/ha dan 408,78 kg/ha, secara berurutan, sedangkan diluar kawasan konservasi adalah 33,05%, 1.058 ind/ha dan 307,77 kg/ha biomassa ikan target.Jumlah jenis ikan karang di kawasan konservasi meningkat, yaitu 60 jenis tahun 2010 menjadi 83 jenis pada tahun 2013 dan rata-rata hasil tangkapan tahun 2008 yaitu 3,03 kg/trip dan tahun 2013 yaitu 3,6 kg/trip. Dapat disimpulkan bahwa kondisi karang dan komposisi jenis dan ukuran ikan lebih baik di dalam kawasan konservasi berbanding diluar kawasan.Kata kunci: Kawasan Konservasi; Ikan karang; Pulau Weh

Reef Fish Species

Specifying annual catch limits for artisanal fisheries, low economic value stocks, or bycatch species is problematic due to data limitations. Many empirical management procedures (MPs) have been developed that provide catch advice based on achieving a stable catch or a historical target (i.e., instead of maximum sustainable yield). However, a thorough comparison of derived yield streams between empirical MPs and stock assessment models has not been explored. We first evaluate trade-offs in conservation and yield metrics for data-limited approaches through management strategy evaluation (MSE) of seven data-rich reef fish species in the Gulf of Mexico. We then apply data-limited approaches for each species and compare how catch advice differs from current age-based assessment models. MSEs identified empirical MPs (e.g., using relative abundance) as a compromise between data requirements and the ability to consistently achieve management objectives (e.g., prevent overfishing). Catch advice differed greatly among data-limited approaches and current assessments, likely due to data inputs and assumptions. Adaptive MPs become clearly viable options that can achieve management objectives while incorporating auxiliary data beyond catch-only approaches.
