| Abstract | ||
| Oryzias celebensis, an endemic ricefish species of Sulawesi, Indonesia, plays a crucial role in ecological studies and conservation due to its sensitivity to environmental changes. This study aimed to analyze the morphological characteristics and habitat conditions of O.celebensis by examining morphometric and meristic traits and assessing water quality parameters across different locations in South Sulawesi. Morphometric analysis was conducted using conventional measurement techniques, while meristic traits were determined by counting key anatomical structures. Habitat conditions were evaluated based on temperature, salinity, dissolved oxygen (DO), and pH. The findings indicate significant variations in standard length, pelvic fin height, and body depth across different sampling sites, suggesting possible genetic stability and environmental influences on growth patterns. In addition, this study highlights that O. celebensis thrives in freshwater environments with slow currents, aquatic vegetation, and moderate dissolved oxygen levels, making it a potential bioindicator species. The results provide essential data for conservation efforts and the sustainable management of this endemic fish species. | ||
