Abstract


Penelitian ini bertujuan untuk mengetahui jenis dan kelimpahan ikan yang terdapat di Karang Branching, Pulau Lengkuas Kabupaten Belitung. serta mengetahui Indeks Keanekaragaman dan Keseragaman ikan yang terdapat di Karang Branching, Pulau Lengkuas Kabupaten Belitung. Metode yang digunakan dalam penelitian ini adalah metode survei. Dilaksanakan pada bulan Juni sampai Agustus 2013 di Pulau Lengkuas Kabupaten Belitung. Berdasarkan hasil penelitian terdapat 17 jenis ikan karang yaitu Siganus gulatus (baronang), Epibulus msidlator (tikus-tikus), Scarus rivulatus (kakak tua), Hemigymnus melapterus (nori merah), Halichoeres hortulanus (piso-piso), Caesio cuning (platak), Cheilimus fasciatus (betok biru), Pomacentrus coelestis (ekor kuning), Heniochus varuis (kepe-kepe monyong), Scarus iwulatus (keling tanduk), Celiscus strigatus (betok sri gunting), Scolopsis margarefiter (kepe-kepe susu), Chelmon rostrastus (keling perak), Hovaculichthys taeniorys (tanda-tanda), Lutjanus fulvilamma (nori monyong), Chaetodon kleini (kakak tua merah), Paraglyphidodon nogoris (kepe-kepe tanduk). Nilai indeks keanekaragaman (H’) Ikan Karang di lokasi sebesar 2,553, dan nilai indeks keseragaman (e) 0,901, hal tersebut menunjukkan bahwa di perairan tersebut ada dominasi salah satu spesies yaitu Pomacentrus coelestis.
