Abstract: The present study has been carried out to determine the water quality in terms of physico-chemical and biological factors in fish pond in Jalandhar city of Punjab, India. The surface temperature varied from 26.3 to 37.1°C. Dissolved oxygen and pH fluctuated from 8.5 to 11.5 mgL^{-1} and 7.6 to 8.4 respectively. The conductivity, turbidity and total dissolved solids varied from 445 to 650 μΩW/cm, 6.00 to 11.00 NTU and 210 to 376 mgL^{-1} respectively. The total hardness and alkalinity range from 113 to 312.5 mgL^{-1} and 145.1 to 216.2 mgL^{-1}. COD and BOD varied from 41.03 to 84.12 mgL^{-1} and 16.05 to 35.10 mgL^{-1}. The concentrations of nitrate (0.92 to 2.00 mgL^{-1}), phosphate (0.08 to 0.301 mgL^{-1}) and sulphate (13.6 to 27.2 mgL^{-1}) varied independently. Total organism found in study pond was 801 out of which 697 were phytoplankton and other 104 were zooplanktons. The numbers of species were different in every month. The diversity of phytoplankton ranged from 1.98 to 2.37 and maximum in July and minimum in March. The diversity index of zooplankton ranged from 0.64 to 0.83 and maximum in July and minimum in June.
