Two deformed Specimens of Schizothoraichthys esocinus were observed among the fish collections from the river Chenab and is the first record for any Himalayan stream. One specimen was recognised by its flat caudal fin base and widely spaced caudal fin lobes. The other showed the post dorsal truncated body with a trough, ventral anal bulge and dome in the caudal peduncle region. X-ray analysis revealed hook shaped vertebral column and aberrations in the various vertebrae and caudal fin bones. Possible cause of aberrations in torrential non polluted river is mechanical injury induced by currents during embryonic development.
