Some Deformed Specimens of Tor tor (Ham.-Buch.) and Tor putitora (Ham.-Buch.) from the Torrential River Chenab, An Important Himalayan River, Draining Union Territory of the Jammu and Kashmir, India

Anomalous specimens of Tor tor and Tor putitora were noticed among fish collections made by fishermen from the river Chenab in Pargwal Wetland area, Akhnoor, over a period of three years, and are reported. Morphologically these deformed fishes were truncated and showed displacement of fins. Radiological analysis exhibited truncated vertebral column and compressed vertebrae with reduced vertebral thickness and intervertebral spaces. A possible cause of these aberrations is fast currents in various Himalayan tributaries of the torrential river Chenab in which Tor generally breeds.
