Abstract:
Background and Objectives: Tulshiganga river is rich in aquatic biodiversity in Joypurhat, Bangladesh. Present survey narrated the venerability and diversity indexes of ichthyofaunal distribution here. Materials and Methods: On-pot data collection and questioner survey was conducted thoroughly among fishermen and tabulated data were analyzed by different population diversity index. Results: About 36 species from 13 different family were reported in this study. The most dominant fishes are included this family Cyprinidae. Based on view of the local fisherman, the three fish species from Siluriformes i.e., Colisa laila, Clarias batrachus and Hara hara under threat. Fourteen species was reports as less common in that area such as Rohtee cotio, Labeobata, Acanthocobitis botia, Anabas testudineus etc. With 1 vulnerable species, 22 were less concern, 2 near threaten, 1 data deficient and 9 fish species not evaluated in International Union for Conservation of Nature (IUCN) red list. Order Siluriformes (19.44%) was higher in amount after order Cypriniformes (44.44%), followed by Perciformes (16.67%). Fish group of Carps shows a higher index of H (Shannon-Weiner) and Glassfish were less. Conclusion: The species composition of family Gobiidae, Clariidae, Sisoridae, Siluridae, Heteropneustidae and Belonidae were similar. Channiformes and mastacem beliformes are newly reported species.
