Abstract
Age and growth of Salmostoma untrahi from Bhadra reservoir region of Karnataka were studied using length frequency analysis during July 1999 to June 2001. The growth increments were different between the sexes of S. untrahi and the growth rate decreased in both sesxes with advancement of age. In general, a sigmoidal growth pattern was observed. Male and female fished attained 117.89 mm and 120.99mm at the end of first year and 128.89mm and 139.48mm at the end of second year respectively. Fluctuations in the grown rate were probably due to the influence of various factors such as geographical, quality and quantity of food, and population density. The life span of the fish was about 1-2 years.
