abstract
The present study was conducted to investigate the effect of three different diets on growth performance of L. rohita for period of 45 days from September to October 2016 at Department of Zoology and Applied Aquaculture, Barkatullah University Bhopal. Three separate L. rohita groups of predetermined weight 3.283-3.609 gm and length 31.9-33.9 cm were fed with three different types of artificially prepared feed viz, control (commercial feed), supplementary plant feed and supplementary animal feed. Among the different treatments L. rohita fed with animal origin diet resulted in the maximum body weight gain (25.143gm) and length gain (31.6cm) which was significantly higher than all the treatment which follow the order of preference as plant diet weight gain (12.074gm) and length gain (20.7cm) and commercial diet weight gain (10.918gm) and length gain (14.4cm). The FCR value for animal diet was significantly better than that for plant diet and commercial diet. It was concluded that efficiency of animal diet was better for the growth of L. rohita and this supported the inclusion of this ingredient in the diet of fishes.
