Archana Sharma and Devendra Mohan

Abstract

Supplementary feed to the spawn and fries of culturable carps play an important role in their increased survival, better growth and increased resistance to the diseases which may result in the success of hatchery operation and ultimately increases the fish production. Ayurvedic herbal drugs Ashwagandha, Safaid Musali, Sataver and Gokhru were mixed with egg yolk as supplementary feed. Two experimental conditions (1) Low temperature low volume (20.0 ± 2.0deg.C and 15 lit) and (2) High temperature high volume (30.0 ± 2deg.C and 80 lit) were selected to access the growth. The foods were provided daily at the rate of 2% of body weight. FCR, SGR were calculated and ANOVA were applied to the results. The increase in length and weight was highest with the food F1 containing Ashwagandha under both LTLV and HTHV conditions. The higher growth was recorded under HTHV condition as compared to LTLV condition. The survival of fries was 100% under both the experimental conditions.
