Abstract

Reef fish utilize coral reef ecosystems as a place to live, foraging, spawning and nurturing. This study aims to determine the abundance of species, diversity and biomass of reef fish found in the waters of Ujong Pancu, Aceh Besar district. This research was conducted in October 2017, there were 5 research location. Data was collected using the Underwater Visual Census (UVC) method. The result show that the highest abundance of reef fish was found in waters of Lhok Mata Ie with a value of 5311.71 Ind/ ha. While the lowest abundance of reef fish was found in Tuan Island waters with a value of 896.67 Ind/ ha. Overall diversity of Ujong Pancu waters reefs is included in the medium-high category. The highest average biomass of reef fish is found in the water of East Batee Island with a value of 100.69 Kg/ ha. While the lowest average biomass of reef fish is found in the waters of West Batee Island with a biomass value 23.87 Kg/ ha. Keywords : Abundance, biomass, diversity, reef fish, Ujong Pancu

Abstract

This study aims to analyze the condition of the coral reef ecosystem including the substrate, genus composition, and the level of coral mortality in the waters of the Malacca Strait, Masjid Raya District, Aceh Besar District. The research was conducted from October 2016 to October 2019 in the waters of the Malacca Strait, Masjid Raya District, Aceh Besar District. The research site is divided into three stations consisting of Lhok Mee Station, Ahmad Rhang Manyang and Benteng Inong Balee Station. Data were collected using the Point Intercept Transect method. The results showed that the condition of coral reefs at Lhok Mee Station was in the damaged category with coral cover ranging from 6.56% - 13.44%. Ahmad Rhang Manyang Station is included in the moderate to good category with coral cover ranging from 38.75% - 67.19%. Meanwhile, Benteng Inong Balee Station is included in the medium category with coral cover ranging from 45.94% - 56.88%. The monitoring results found that 30 coral genera with the highest composition of the coral genera came from the Porites genus, while other coral genera were unevenly distributed. The value of the mortality index for Lhok Mee Station shows a high increase in mortality of live coral to dead coral. Meanwhile, Ahmad Rhang Manyang and Benteng Inong Balee stations have low coral mortality index values.
