Abstract
Scales from 313 specimens of a Himalayan teleost Schizothorax richards onii from the Alaknanda hillstream in the Garhwal Himalayas were read for age determination and calculation of growth parameters. There was a strong linear relationship between fish length and lateral scale rad ius. Annuli formation occurred in August-September coinciding with spa wning and the frequent flash floods in Garhwal. The growth constant pa rameter indicated that the fish enter 'old age' in the fifth year of l ife. Growth rate decreases successively at higher ages.
