The Study of the Relationship between Coral Reef Cover and the Abundance of Coral Fish on the Island of Poncan Gadang, Sibolga City

Introduction

Poncan Gadang Island, located in the city of Sibolga, is a popular destination for various activities such as coastal tourism, underwater exploration, and capture fisheries. However, the diversity of these activities poses a significant threat to the coral reef ecosystem, which is a vital component of the marine ecosystem. The coral reef ecosystem provides a habitat for numerous marine species, including coral fish, and plays a crucial role in maintaining the balance of the marine ecosystem. Therefore, this study aims to evaluate the condition of coral reef cover, abundance of coral fish, and the relationship between the two on Poncan Gadang Island.

Background of the Study

Poncan Gadang Island is a small island located in the city of Sibolga, which is known for its rich marine biodiversity. The island is surrounded by coral reefs, which are home to a variety of marine species, including coral fish. However, the coral reefs on the island are facing significant threats due to human activities such as pollution, overfishing, and climate change. These activities have resulted in the degradation of the coral reef ecosystem, which has a direct impact on the abundance of coral fish.

Methodology

This study was conducted in June 2018 using the Underwater Photo Transect (UPT) and Underwater Visual Census (UVC) methods. The UPT method involves taking photographs of the coral reef area using a camera mounted on a frame, while the UVC method involves counting the number of coral fish in a given area. The results of the study showed that there were 14 types of coral fish classified in 5 families, with a total of 161 identified individual fish. In addition, the average value of the percentage of coral reef cover found was 23.96%, which indicates that the coral reefs on the island are in a damaged category.

Analysis of Coral Reef Cover Conditions

The coral reef cover conditions on Poncan Gadang Island are a cause for concern. The average value of the percentage of coral reef cover found was 23.96%, which is below the optimal level of 50%. This indicates that the coral reefs on the island are in an unhealthy condition, which has a direct impact on the abundance of coral fish. The degradation of the coral reef ecosystem can be caused by several factors, including pollution, overfishing, and climate change.

Abundance of Coral Fish and the Relationship with Coral Reef Cover

The abundance of coral fish on Poncan Gadang Island was found to be correlated with the condition of the coral reef cover. The correlation rate between live coral cover and the number of coral fish was 29.5%, which indicates a sufficient or medium relationship. This means that the better the condition of the coral reef cover, the higher the abundance of coral fish that can be found. This relationship is crucial for the sustainability of the marine ecosystem, as coral fish play a vital role in maintaining the balance of the ecosystem.

The Importance of Protecting the Coral Reef Ecosystem

Given the importance of the role of coral reefs as a habitat for many marine species, as well as its significant function in maintaining the balance of the marine ecosystem, the preservation steps must be taken immediately. The wise management of human activities around Poncan Gadang Island, such as the regulation of ship transportation paths and the application of sustainable fisheries practices, is very important to reduce the negative impact on coral reefs and species that depend on it.

Conclusion

In conclusion, this study highlights the importance of protecting the coral reef ecosystem on Poncan Gadang Island. The coral reef cover conditions on the island are in an unhealthy condition, which has a direct impact on the abundance of coral fish. The relationship between coral reef cover and the abundance of coral fish is crucial for the sustainability of the marine ecosystem. Therefore, it is essential to take immediate action to protect the coral reef ecosystem and maintain the balance of the marine ecosystem.
