Abstract : |
Physico-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 C, 35.83 cm, 5.17 mgl -1, 7.07, 13.1 mgl -1, 32.5 mgl -1, 1.93 mg -1, 0.05mg -1 and 1.19 mgl -1 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., |
