This study involves the study of the diversity of fish fauna in the dam of Amarpura. An ichthyofaunal survey was conducted between January 2019 and January 2020 to determine the diversity and distribution of freshwater fishes in the Amarpura dam. 26 species (9 families) belonging to 6 orders were collected in this study. The Cyprinidae, Heteropneustidae, Ambassidae, and Channidae were the three abundant families. The index of Shannon-Weiner diversity was 1.302. This study has produced baseline data on ichthyofunal diversity that can now be regularly monitored and form the basis for future plans of fisheries and conservation.
