Abstract– The aquatic ecosystem’s overall biodiversity can be measured using the hydrographic macroinvertebrates. Numerous researchers have emphasised the significance of bottom fauna as a connection in the energy flow from primary productivity to fish output in the lotic ecosystem’s productivity. The results of a thorough investigation of the variety of macro- hydrographic invertebrate fauna in the Koshi River near Saharsa, Bihar have been done in the present study. The current study was worked on for a full year, from November 2021 to October 2022. Twenty different species of macroinvertebrate were identified over the course of the study. This research paper presents a comprehensive study on the hydrographic macro invertebrate diversity and distribution patterns in the Koshi River basin. The Koshi River, a major river system in the region, supports a diverse range of fish species that play important ecological and economic roles. This study aims to document the heterogeneity of hydrographic macro invertebrate fauna, analyze their distribution patterns, and discuss the potential factors influencing fish diversity in the Koshi River.
