Abstract:
The experiment was conducted in the laboratory in circular plastic troughs of 70 liter capacity, marked as T0 and T1, respectively for 60 days. Each trough was stocked with 26 uniform size (average 42 mm length and 0.96 g body weight) healthy fingerlings of Labeo rohita (produced and transferred from Fish Seed Hatchery Pantnagar).The fingerlings averaging 0.96 gm were reared on two artificial feeds D0 and D1, one with a vitamin and mineral premix (1 % in dry diet) and the other without it. The fishes were fed twice daily at a fixed feeding rate of 4 % wet body weight per day. The growth increment of fingerlings was recorded at regular intervals and the quantity of feed given was adjusted accordingly. Physico-chemical parameters of water were evaluated at weekly interval using standard methods and no significant difference was observed between the treatments (P < 0.05). At the termination of the experiment the survival in the treatment T1, fed on feed with the premix was 92.31 % and the average weight gain of fish was 19.66 gm. Survival in the control treatment T0 was 84.61 % and the average weight gain by the fish was recorded as 9.90 gm.
