Abstract
The present study was conducted at the Instructional Fish Farm, College of Fisheries, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, Uttar Pradesh, in earthen ponds (8m×8m×1m). The experiment for 90 days, using Labeo rohita advanced fingerlings (avg. wt. 30.0 ± 0.5g) under sodic soil conditions. Five treatments were taken in triplicate, with 50 fingerlings per pond. T1 served as the control with traditional feed only (MOC+RB in 1:1 ratio, 5% of total fish body weight). T2 and T3 were fertilized with cattle dung (20 and t ha−1 yr−1) respectively. T4 and T5 received poultry droppings (10 and 7.5 t ha−1 yr−1) respectively. Results showed negative allometric growth (b<3), indicating fish becoming slimmer with length increase. Final weight gain was highest in T4 (110.9±0.9 gm) and T2 (108.7±0.88 gm), and lowest in T1 (70.7±0.49 gm).
