Abstract
The levels of the physicochemical regime of two selected fish ponds in Gwagwalada and Kuje Area Councils of the Federal Capital Territory were determined from July to September ( rainy season) by using standard methods and equipment. The values of physico-chemical parameters of both fish ponds in the rainy season in Gwagwalada and Kuje respectively was between 87.75 ± 7.26 to185 ± 7.43ppm, for total alkalinity, 0.78 ± 0.44mg/L to4.06 ± 0.43 mg/L for BOD, 58.75± 7.81ms/cm and 262.23 ± 53.90ms/cm for conductivity, 7.13 ± 1.10 mg/L to 8.50 ± 0.23 mg/L for DO, 7.74 ± 1.03 to 9.02 ± 1.06 for pH, 24.5 ± 1.41 to 28 ±0.70oC for temperature and 2.15 ± 0.49 m to 4.45 ± 0.46m for turbidity. There was no significant difference (p > 0.05) in the levels of physico-chemical parameters between the fish ponds in Gwagwalada and Kuje. Fish pond A Kuje had the highest fish mortality 480 (24.10%) and fish pond B Gwagwalada had the highest 1050 (52.60%).Strong positive correlation(r=0.7,0.9,1) existed between fluctuation in physicochemical parameters and fish mortality in all the ponds except fish pond B Gwagwalada. Most of the Physicochemical parameters were also strongly correlated with one another. The essence of monitoring water quality in fish ponds, clearing ponds of rotten leaves, unconsumed feed and faecal matters to reduce organic matter which can impact adversely on water quality is also highlighted.
