Abstract:
The experiment on "Effect of partial replacement of fish meal with moringa leaf meal in the diet of Labeo rohita fry" was conducted during September to November, 2019 in the wet laboratory of College of Fisheries Science, Veraval. The objective of present study was to find out the effect of partial replacement of fish meal with moringa leaf meal in the diet of L. rohita fry. In this experiment, the data pertaining to growth, survival rate, feed conversion ratio and protein efficiency ratio of L. rohita fry at partial replacement of moringa leaf meal were evaluated. L. rohita fry (Avg weight 0.058g) were stocked at a density of 10 nos/ aquaria in all 20 aquaria. Five experimental diets were formulated and prepared. Approximately 35% protein level was maintained in all the diets. Diet prepared without moringa leaf meal protein (control diet) and other four diets containing 5%, 10%, 15% and 20% moringa leaf meal protein were prepared and fed to L. rohita fry at 10% body weight two times in a day for 60 days. Highest mean weight gain, SGR, PER and lowest FCR were recorded in control diet (T1). 100% Survival rate was recorded in treatment including control diet. The result of present investigation revealed that partial replacement of fish meal with moringa leaf meal significantly reduces the mean weight gain, SGR and PER and increases the FCR of L. rohita fry.
