This study presents a comparative assessment of ichthyofaunal vulnerability and diversity indexes in the Tulsiganga River, Bangladesh. Ichthyofauna, representing a critical component of aquatic ecosystems, face various anthropogenic pressures and environmental changes, necessitating effective monitoring and conservation measures. Through field surveys and data analysis, this research examines the vulnerability and diversity of fish species inhabiting the Tulsiganga River. Vulnerability indexes are evaluated based on ecological traits and anthropogenic threats, while diversity indexes assess species richness, evenness, and distribution patterns. The findings provide insights into the conservation status of fish populations in the Tulsiganga River and contribute to ongoing efforts aimed at promoting sustainable management practices and biodiversity conservation in freshwater ecosystems.
