Abstract: | Ekosistem terumbu karang merupakan ekosistem produktif untuk perikanan dan organisme akuatik lainnya. Ekosistem terumbu karang menjadi habitat vital bagi komunitas ikan khususnya ikan terumbu. Ikan terumbu adalah komponen penting di lingkungan perairan, keberadaan komunitas ikan terumbu pada ekosistem terumbu karang penting untuk diketahui, karena peran dan fungsi secara ekologi ikan dalam menjaga kestabilan komunitas terumbu karang dan keseimbangan komponen penyusun ekosistem terumbu karang lainnya. Penelitian ini bertujuan mengetahui struktur komunitas ikan terumbu di Pulau Tidung.
Penelitian ini dilakukan di Pulau Tidung pada tanggal 9 - 12 Juni 2022. Metode
pengambilan data ikan terumbu menggunakan Underwater Visual Census (UVC)
dengan transek 50 meter, dan diletakkan tiga transek di setiap stasiunnya. Data ikan
terumbu dianalisis dengan tiga indeks komunitas, yaitu indeks keanekaragaman,
indeks keseragaman, dan indeks dominansi. Hasil penelitian ditemukan 3982
individu ikan terumbu, 24 famili dan 91 spesies. Komposisi ikan indikator sebesar
2,44%, target 17,20%, dan ikan mayor sebesar 80,36% dari total individu yang
ditemukan. Nilai rata-rata indeks keanekaragaman 2,77, keseragaman sebesar 0,88,
dan dominansi 0,08. Nilai ini menunjukkan bahwa kondisi komunitas ikan terumbu
di Pulau Tidung tergolong baik, stabil, dan tidak ada dominansi antar spesies. Coral reef ecosystems are productive ecosystems for fisheries and other aquatic organisms. Coral reef ecosystems are vital habitats for fish communities, especially reef fish. Reef fish are important components in the aquatic environment, the existence of coral fish communities in coral reef ecosystems is important to know, because of the ecological role and function of fish in maintaining the stability of coral reef communities and the balance of other components of coral reef ecosystems. This study aims to determine the structure of the reef fish community on Tidung Island. This research was conducted on Tidung Island from 9 June to 12 June 2022. The reef fish data collection method uses Underwater Visual Census (UVC) with a 50 meter transect, and placed three transects at each station. Reef fish data were analyzed with three community indices, namely diversity index, uniformity index, and dominance index. The results of the study found 3982 individuals of reef fish, 24 families and 91 species. The composition of indicator fish is 2,44%, target is 17,20%, and major fish is 80,36% of the total individuals found. The average value of diversity index is 2,77, uniformity is 0,88, and dominance is 0,08. This value indicates that the condition of the reef fish community on Tidung Island is good, stable, and there is no dominance between species. |
