E. 102000310Physico-chemical characteristics were observed in carp rearing ponds at Bangladesh Agricultural University, Mymensingh, Bangladesh under two different treatments. Mean values of temperature, Secchi depth, dissolved oxygen, pH, chlorophyll-a, total alkalinity, nitrate nitrogen, ammonia nitrogen and phosphate phosphorous were 29.8 PC, 35.83 cm, 5.17 mgI1, 7.07, 13.1 mgl1, 32.5 mgl1, 1.93 mgl1, 0.05 mgl1 and 1.19 mgl1 respectively over the experimental period. All the measured water quality parameters varied little among the ponds and no discernible trends were apparent in either or between pond conditions.]]>Ahmed, Z.F., M.A. Wahab, M.A.H. Miah and M.E.
