The health of an artificial or natural fish pond is determined by the state of its physiochemical parameters. This study was therefore, designed to examine the level of physicochemical regime of four selected fish ponds, viz; Zogarawa fish pond, Bagauda fish seed multiplication centre, Fagam fish pond and Khasu integrated fish pond in Dawakin Tofa, Bebeji and Kumbotso Local Government Areas of Kano State from July 2014 to December 2014 (rainy season and harmattan season). The techniques for determining the parameters were as described in the instructional manual of the HANNA Instruments (HI©) and JENWAY(®) Water Analysis Kits. The physicochemical parameters of the pond water was analyzed and determined using one way analysis of variance (ANOVA) with the aid of INSTAT 3 statistical software for window version 2003. The values of the physicochemical parameters of four fish ponds in the study area were between 25.7±1.07 to 27.8±1.03oC for temperature, 6.8±0.03 to 7.1±0.62 for pH, 2.01±0.03 to 3.08±0.13mg/L for dissolved oxygen, 296.3±1.73 to 613.7±3.03 μs/cm for electrical conductivity, 63.0±1.90 to 153.0±2.76mg/L for total hardness and 20.5±2.35 to 100.6±4.98mg/L for total suspended solids. There was no significant difference (p>0.05) in the levels of temperature, pH and dissolve oxygen but there is significant difference (p<0.05) in electrical conductivity, total hardness and total suspended solids between the ponds. The studied ponds are in a stable state and suitable for fish farming with the idea of re-introduction into water bodies with insufficient fish populations.
