Abstract
The present study is conducted at Bhadar reservoir landed of Rajkot in Gujarat, India. Duration of work was 8 months and total number of sample was 225. The spawning percentage was higher during the month of August (82.56%) and lower in December (53.34%). The averaged total spawning percentage was 60.02%. The absolute fecundity of W. attu ranged from 16565 – 29883. Monthly average fecundity of W. attu was 22171. The annual average fecundity per gram body weight was 10. The average fecundity determined for the study period of one year was 22717. The annual average ova diameter was 1.38 cm (range 1.1 – 1.9 cm).
