    Abstract
    The research with the title “Study of Reef Fish Diversity At The East Part Oceanik Of Rubiah Island Nanggroe Aceh Darussalam” have been done at May 2009. This Research is done with the method of Purpossive Random Sampling that is determine 2 research station of pursuant to difference of society activity that goes on around this oceanik. Reef fish survey done at the transect that sized 4 x 50 metres by 3 restating times rill each research station. This research target is to see the diversity of reef fish and the correlation between chemical physical factor with the reef fish diversity. From result identify to the reef fish obtained a class reef fish which pertained in 1 ordo, 14 set of family and 33 genus and 50 species. The highest abundance and relative abundance is obtained at Acanthurus leucosternon that is 0,370 ind/m2 and 5,150 %. The lowest abundance and relative abundance at Labropsis sp that is 0,005 ind/m2 and 0,086 %. The highest diversity index are at station 1 that is 3,472 while the lowest are at station 2 that is 3,343. Highest similarity index there are at station 1 that is 0.956 while the lowest of similarity index there are at station 2 that is 0,955. From result of correlation analysis known that the relation between variety index and chemical physical factor value is strong correlation
     
    Penelitian dengan judul “Studi Keanekaragaman Ikan Karang Di Kawasan Perairan Bagian Timur Pulau Rubiah Nanggroe Aceh Darussalam” telah dilakukan pada bulan Mei 2009. Penelitian ini dilakukan dengan metode Purpossive Random Sampling yaitu menentukan 2 stasiun penelitian berdasarkan perbedaan aktivitas yang berlangsung di Perairan tersebut. Pengamatan Ikan Karang dilakukan pada transek yang berukuran 4 x 50 meter sebanyak 3 transek pada setiap stasiun. Tujuan penelitian ini adalah untuk melihat keanekaragaman ikan karang dan hubungan antara faktor fisik kimia dengan keanekaragaman ikan karang. Dari hasil identifikasi diperoleh ikan karang yang termasuk kedalam kelas Osteichtyes yang tergolong dalam 1 ordo, 14 famili, 33 genus serta 50 spesies. Nilai Kepadatan dan kepadatan Relatif tertinggi terdapat pada Acanthurus leucosternon dengan nilai masing-masing 0,370 ind/m2 dan 5,150 %. Nilai Kepadatan dan Kepadatan Relatif terendah terdapat pada Labropsis sp. yaitu 0,005 ind/m2 dan 0,086 %. Indeks keanekaragaman tertinggi terdapat pada stasiun 1 yaitu 3,472 sedangkan terendah terdapat pada stasiun 2 yaitu 3,343. Indeks keseragaman tertinggi terdapat pada stasiun 1 yaitu 0.956 sedangkan terendah terdapat pada stasiun 2 yaitu 0.955. Dari hasil analisis korelasi diketahui bahwa hubungan antara indeks keanekaragaman dengan nilai faktor fisik kimia berkorelasi kuat
