Abstract: The present experiment was designed to investigate the effect of poultry droppings on the water quality and growth parameters of Indian major carp during April 2012 to May 2013. Three ponds were selected each having an area of 1000m2. Control (T0) pond did not receive any additive while treatment 1 (T1), treatment 2 (T2) and treatment 3 (T3) were manured with poultry dropping. Water temperature, pH, dissolved oxygen, specific conductivity, alkalinity, total hardness, turbidity and total dissolved solids were ranged 15.4 -29.6 0C and 15.4 - 29.7 0C, 6.1-7.6 and 6.2-7.4, 6.5-9.8 mg/l and 6.8- 9.7 mg/l, 0.203-0.569 µS/cm and 0.286-0.584 µS/cm, 62-114 mg/l and 89-121 mg/l, 62-138 mg/l and 91-134 mg/l, 15.83-6.68NTU and 23.41-52.21NTU, 68-264 mg/l and 168-287 mg/l in the treatments and control pond respectively. The net production and fish growth in the treatment ponds was maximum in comparison to control pond. The significantly (p<0.05) highest net production of fishes was recorded in T2 (3853.20 kg/ha/yr) in comparison to T0 (1227.69 kg/ha/yr). The percentage increase of fish production in T1, T2 and T3were 56%, 68% and 53% respectively as compared to T0. The favourable water quality and net production of fish in T2 comparison to T1, T3 and T0 affirmed that the droppings of 90 numbers of poultry birds was the standard dose for integrated fish poultry farming in foothills of Arunachal Pradesh.
