Abstract : Fish fauna of the river Ganga from Gangotri to Kanpur consisted of 140 fish species from 9 orders and 25 families; 63 fish species from 6 orders and 12 families in the mountain section (MS), while 122 species from 9 orders and 25 families in the Plains section (PS) of Upper Ganga. Cypriniformes and Cyprinidae were most species rich order and family in both sections. Forty six fish species primarily Cypriniformes and Siluriformes are common to both sections, only 17 in MS and 76 in PS. Orders Tetradontiformes, Osteoglossiformes and Clupeiformes were present in PS only. The taxonomic richness in the MS was low compared to PS. Probably motility and physiological requirements in respect of tolerance for temperature restrict faunal elements.

Keywords : Cyprinidae, Fish distribution, Gangetic plains, Himalaya, River continuum.
