Abstract: Fish are keystone species in many aquatic food webs, where they may regulate the abundance and diversity of prey organisms through top-down effects. Present study was aimed to analyse the ichthyofaunal diversity of Bhakra-Yamuna link canals in the Narwana region of Haryana from January, 2013 to December, 2013. The total fish composition comprised 12 species of fishes belonging to 4 families and 2 orders were identified. The most abundant order of fish was the Cypriniforimes (9 species). Relatively higher numbers of fish species were recorded at site S3 as compared to site S1 and S2.
