    Abstract: The study was conducted to determine the changes in the Gonadosomatic 
  Index (GSI) of an Indian major carp, <I>Labeo rohita</I>. The fish has only 
  one spawning season of short duration, running from July to August as indicated 
  by the peaks of GSI and the diameter of oocytes and testicular lobules. Both 
  males and females mature simultaneously. The minimum GSI for female was 0.74&plusmn;0.12 
  in resting phase and maximum was observed in the spawning phase (16.49&plusmn;1.70). 
  The GSI for males was minimum in resting phase (0.087&plusmn;0.004) and maximum 
  in spawning phase (2.02&plusmn;0.181).
