Abstract : |
Observation of water quality parameters was made in carp nursery ponds at Bangladesh Agricultural University, Mymensingh, Bangladesh under two different conditions. Mean values of temperature, Secchi depth, dissolved oxygen, pH, chlorophyll-a, total alkalinity, nitrate nitrogen, ammonia nitrogen and phosphate phosphorous were 30.58أƒâ€ڑأ‚آ°C,51.83 cm, 5.7 mg-1, 6.88, 5.27 mg-1, 26 mgl-1, 1.12 mgl-1, 0.02 mgl-1 and 0.78 mgl-1 respectively over the experimental period. All the measured physico-chemical characteristics varied little among the ponds and no distinguishable trends were discernible in either or between conditions., |
