Adanya pemanasan global dan penangkapan ikan menjadi penyebab kerusakan komunitas ikan karang. Penelitian ini bertujuan untuk mengidentifikasi struktur komunitas ikan karang di Pulau Peucang, Taman Nasional Ujung Kulon, dengan menganalisis komposisi spesies, keanekaragaman, keseragaman, dominansi, densitas dan prevalensi ikan karang. Pengumpulan data dilakukan menggunakan metode Underwater Visual Census (UVC) di lima stasiun pengamatan denan panjang transek 50 meter. Parameter kualitas air yang diamati meliputi suhu, salinitas, dan oksigen terlarut. Hasil penelitian mecatat 48 spesies, 29 genus dan 16 famili, dengan famili Pomacentridae mendominasi komunitas ikan karang. Nilai indeks keanekaragaman (H’) tertinggi tercatat pada stasiun 1 (H’=2,45), sedangkan nilai terendah di stasiun 5 (H’=1,5). Indeks keseragaman (E) tertinggi di stasiun 1 (J’==0,78), dan indeks dominansi (D) tertinggi di stasiun 5 (D=0,405). Hasil ini menunjukan bahwa kondisi lingkungan seperti salinitas, suhu dan oksigen terlarut mempengaruhi distribusi dan kelimpahan ikan karang di lokasi penelitian.

Global warming and fishing have caused damage to the reef fish community. This study aims to identify the structure of the reef fish community on Peucang Island, Ujung Kulon National Park, by analyzing species composition, diversity, evenness, dominance, density, and prevalence of reef fish. Data collection was conducted using the Underwater Visual Census (UVC) method at five observation stations with a 50-meter transect length. Air quality parameters observed included temperature, salinity, and dissolved oxygen. The results of the study recorded 48 species, 29 genera, and 16 families, with the Pomacentridae family dominating the reef fish community. The highest diversity index (H’) value was recorded at station 1 (H’=2.45), while the lowest value was at station 5 (H’=1.5). The highest uniformity index (E) was at station 1 (J’==0.78), and the highest dominance index (D) was at station 5 (D=0.405). These results indicate that environmental conditions such as salinity, temperature, and dissolved oxygen influence the distribution and mapping of reef fish at the research site.
