To understand the applicability of restricted feeding in the fingerlings of the Indian major carp. rohu, Labeo rohita, an 60-day feeding experiment was conducted in the laboratory involving alternate day feeding of high and low protein diet, respectively. To support this experiment three experimental isocaloric (401.32 to 410.28 kcal/100g) diets of 30%, 25% and 20% crude protein designated as diet A, diet B and diet C, respectively were prepared, using locally available feed ingredients and three different feeding schedules of high protein diet continuously (diet A-30%). alternate feeding of 1-day diet A followed by 1-day diet B (lA/1B) and alternate feeding of 1-day diet A followed by 1-day diet C (lA/IC) were tested. Overall digestive enzymes activity was reported to be higher in the group fed A/1B) and the lowest was recorded in the group T2 fed A/C but histological there is no significant difference is observed.
