Abstract
The Golden Mahseer (Tor Putitora) forms an important fishery resource in coldwater areas of Himalaya, India. The study covers reproductive factors of T. putitora from Anji Mahseer Hatchery Reasi, Jammu & Kashmir. Fecundity and Gonadosomatic Index (GSI) of T. putitora was calculated monthly for a period of six months from March’ 2011 to August’ 2011. The observations related to fecundity and GSI are based on six female specimens of T. putitora ranging from 260mm to 550mm in total fish length and weight ranging between 280 grams to 800 grams. The mean value of fecundity was estimated as 5566 eggs for a fish with a mean total body length of 395mm and mean body weight of 455gms. The value of GSI was found to increase from March onwards reaching a peak in June, July and August. The peak was maintained in June, July and august, the highest value for GSI was calculated as 10.812 in the month of August.
