Abstract: The present investigation was carried out to study the ichthyofauna diversity of Hiran-II reservoir. Monthly samples were collected from the selected sites during July 2018 to March 2019. The study revealed that physico-chemical parameters of Hiran-II Reservoir, commercial importance 28 fish species were collected which are belonging to 19 genera, 10 families and 6 orders. Investigated the occurrence of Cypriniformes were dominant (13 species) followed by Siluriformes (6 species), Perciformes (3 species), Channiformes (3 species), Osteoglossiformes (2 species) and Synbranchiformes (1 species). Highest diversity of fish were recorded in the month of December (post monsoon). The range of physico-chemical parameters were observed such as water temperature 21.77°C – 28.43°C, pH 7.57 – 8.43, electrical conductivity 284.3–367.7μmhos/cm, transparency 19.67 – 30.26/cm, dissolved oxygen 6.77– 9.33mg/l, BOD 6.27- 8.47mg/l, total alkalinity 212.33–254.67mg/l; total hardness 145– 194mg/l, TDS 212.3 – 271.7mg/l, TSS 25.87 – 38.90mg/l, nitrate 0.92 – 2.04, and phosphate 0.59 – 0.90mg/l.
