Abstract
The experiment on “Effect of partial replacement of fish meal with earthworm
meal in the diet of Labeo rohita fry” was conducted during the September to
November, 2018 in the wet laboratory of College of Fisheries Science, Junagadh
Agricultural University, Veraval. The objective of the present study was to find out
the effect of partial replacement of fish meal with earthworm 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
earthworm meal were evaluated. L. rohita fry (average weight 0.103gm) were stocked
at a density of 10 nos. /aquarium in all 20 aquaria. Five experimental diets were
formulated and prepared. Approximately 35% protein level was maintained in all the
diets. Diet prepared without earthworm meal protein (control) and other four diets
containing 5%, 10%, 15% and 20% earthworm 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 10% (T3) earthworm meal protein
diet. 100% Survival rate were recorded in treatment including control diet. The result
of the present investigation revealed that partial replacement of earthworm meal
significantly affected the mean weight gain, SGR, survival rate, FCR and PER of
L. rohita fry
