Abstract

The paper highlights the results of experiments conducted on artificial propagation of Schizothorax richardsonii (Gray) in Central Himalayas. The species in Kumaon Himalayan waters is an annual spawner and breeds between September to October, exhibiting migration to nearby upstream regions for spawning. Overall, survival rate of 80.0 to 85.0% from fertilized egg to fry
(22.0-24.5 0C) and 35.0 to 45.0 % from fry to fingerlings was recorded during the experimental trials conducted under farm conditions. Fry attained total length between 75.0 to 100 mm (weight 4.0 to 6.0 g) with a cumulative survival of about 45.0% within a rearing period of one year. Other management practices evolved for mass scale seed production and rearing of S. richardsonii under farm conditions are discussed in the paper
