ABSTRAK

Penelitian ini mengenai jumlah dan variasi ikan karang di perairan Tanjung Kunyit, Kabupaten Kotabaru. Pengolahan data yang digunakan kelimpahan ikan, indeks keanekaragaman, dan hubungan presentase tutupan karang dengan kelimpahan ikan target. Tutupan karang di perairan Desa Tanjung Kunyit sekitar 55,6% - 73,3% dengan kualitas baik. Kami menemukan berbagai jenis ikan target seperti Seranidae, Hamulidae, Siganidae, Scaridae, Lutjanidae, Lethrindae, Dasyatidae, dan 7 spesies ikan target lainnya. Jumlah ikan target berkisar antara 9-20 ekor/m2. Hubungan antara tutupan karang dan kelimpahan ikan target sangat kuat, dengan koefisien korelasi (R=0,9967) yang menunjukkan hubungan yang kuat. Kemungkinan ada faktor lain yang mempengaruhi juga. Kualitas air sebagian besar memenuhi standar Kepmen LH No. 51 Tahun 2004.

ABSTRACT

This research is about the number and variety of reef fish in the waters of Tanjung Kunyit, Kotabaru Regency. Data processing used fish abundance, diversity index, and the relationship between the percentage of coral cover and the abundance of target fish. Coral cover in the waters of Tanjung Kunyit Village is around 55.6% - 73.3% with good quality. We found various types of target fish such as Seranidae, Hamulidae, Siganidae, Scaridae, Lutjanidae, Lethrindae, Dasyatidae, and 7 other target fish species. The number of target fish ranged from 9-20 fish/m2. The relationship between coral cover and target fish abundance was very strong, with a correlation coefficient (R=0.9967) indicating a strong relationship. It is possible that there are other factors that influence as well. Most of the water quality meets the Minister of Environment Decree No. 51 of 2004.
