Abstract
Coral reefs play a vital role in providing habitat for reef fish and other invertebrates, yet there is increasing pressure on the systems. Moreover, only a few studies and information were provided about coral reef’s status in Tulungagung. The purposes of this study were to determine substrate cover, diversity of reef fish, and invertebrates. The study was carried out in Brumbun Bay, Tulungagung in October 2017. The methods were done by diving at depths of 9 to 14 meters. The data obtained then were analyzed descriptively to describe the current status of coral reefs. The result showed that 34% of the substrate was covered by hard coral, 45% by sand, rock, coral fragments, soft corals, and algae. Snapper is known as a reef fish group that is more commonly found. The results showed that there were no invertebrates found during the dive. Based on the results, the status of coral reefs in Tulungagung was rated moderate. It is imperative to note down that trash nets and plastic waste was found frequently. This study provides crucial information about the current status of coral reefs in Brumbun Bay, Tulungagung which in the future can be used as a reference study.
