| Abstract | ||||
| Mangrove ecosystems play a crucial ecological role in supporting the survival of various aquatic organisms, particularly fish. In the coastal area of West Aceh District, mangroves are distributed across several sub-districts, covering a total area of approximately 394.96 hectares. This ecosystem experienced significant degradation following the 2004 tsunami and continues to face anthropogenic pressures, including land clearing and infrastructure development. This study aimed to assess fish diversity and the ecological sustainability of mangrove ecosystems in the coastal region of West Aceh. The research was conducted from October 2024 to March 2025. Data were collected using a quantitative descriptive approach. Analyses were performed using Microsoft Excel and the Rapfish (Rapid Appraisal for Fisheries) software. Based on the diversity index analysis, the average index in the Samatiga waters was 2.03, while in the Lamnaga waters it was 1.63, indicating a moderate level of fish diversity in both locations. Using the Multidimensional Scaling (MDS) method, the ecological sustainability index for mangroves in the Samatiga region was found to be 80.17, while the index for the Lamnaga region was 77.14. These results classify both areas as having good or very sustainable ecological conditions. | ||||
