Condition of the Coral Reef of Maitara Island Based on Chaetodontidae Fish for Coral Reef Improvement in North Maluku Province

摘要

This study aims to look at the level of damage to coral reefs based on Chaetodontotidae fish and biodiversity of Chaetodontidae fish on Maitara Island. This research was conducted in April to May 2019 at 2 stations. Collecting coral reef data using the Line Intercept Transect (LIT) method which is placed parallel to the shoreline, while Chaetodontidae fish uses the Visual Method Census method. During the study, 20 species of Chaetodontidae were found, representing 2 genera; namely Chaetdon (15 species), and Chelmon (5 types). Fluctuations in the index of diversity, diversity and dominance can be used as indicators of damage to coral reefs. Diversity (H') ranges from 0.67-1.01, the percentage of live coral cover between 10.80% to 15.30%. The damage of the Coral Reef of Maitara Island is in the damaged category based on the Minister of Environment Decree of 2001. The correlation between the percentage of live coral and Chaetodontidae fish is positive, the determinant coefficient of each species is more than 95%. Low species diversity and individual dominance of one type of Chaetodontidae show that coral reef damage has been caused by anthropic activity, so the loss of most of the main meal of Chaetodontidae fish is coral polyps.
