The present paper deals with food analysis and feeding behavior of the snow trout Schizothorax richardsonii (Gray) which is a cold water herbivore fish by nature. It is locally called Asela and is distributed in Himalayan and sub-Himalayan regions of Asia and has considerably attracted the attention of researchers due to its high productivity. The health and growth of fishes is greatly influenced by their nutrition and feeding. It has been observed in the present study that the adult fish

... lly feeds on diatoms and algae. An experiment was conducted on artificial feeding of fish by giving three different types of food, i.e., formulated diet as control, periphton based diet and a mixture of both in different artificial raceways. It was observed that the fish conversion ratio (FCR) of the fish pooled in the raceway one (R1), i.e., feeding with formulated was high (6.85) due to balanced nutrients. It is recommended that with the introduction of balance artificial diet may be helpful in increasing the production of S. richardsonii.
