Induced spawning of the endangered golden mahseer, Tor putitora, with ovaprim at the State Fish Farm near Dehradun

Endangered golden mahseer, Tor putitora, has been successfully bred during September 1997 at the State Fish Farm near Dehradun (Baint-wali-Mandi) by intramuscular administration of the synthetic hormone drug ovaprim (single dose, 0.20 ml/kg body weight) to the females. Since males were mature and oozing under pond conditions, they were not given any treatment. After 24 hours, about 4,000 viable eggs were released and fertilised with the fresh milt. About 70-80 % fertilization and 60-65% hatching success were observed.
