Abstract


Assessment of the quality of water in fish pond is necessary in order to determine its suitability for fish production.  One of the problems facing fish farming is inadequate monitoring of water used in fish pond and this has posed serious threat to survival and growth of fish. Constant monitoring of the water from fish farm through physicochemical analysis is one of the main solutions to this problem. This study is aim at examine the seasonal variation in physicochemical properties in water samples from Osagin Fish farm in Akinyele Local Government, Ibadan, Oyo State. Water samples were collected under aseptic condition at a month interval for a year period. Physicochemical properties were assessed by standard methods. The water temperature ranged from 23.67 to 30.00oC,  Air temperature ranged from 24.00-33.67oC, the surface pH ranged from 6.73 to 8.80 mg/L, Dissolved oxygen 4.87-8.07 mg/L, Electrical conductivity of the surface water varied from 6.53 µS/cm to 15.23 µS/cm, Total Dissolved Solids ranges from 15.90-52.27 mg/L, Total hardness ranged between 28.3 and 64.67 mg/L, Total Alkalinity varied from 29.67 to 49.67 mg/L, Phosphate ranged from 0.16 to 1.95 mg/L, Chloride ranges between 8.50 to 10.72 mg/L, Nitrate varies from 1.24 to 3.97 mg/L, Calcium ranged from 18.67 to 84.67 mg/L, Sodium ranges between 22.94 to 26.92 mg/L, Magnesium varied from 1.08 to 1.38 mg/L, Potassium ranges between 1.01 to 1.09 mg/L and Iron varied between 0.29 and 0.59 mg/L. The findings of seasonal variation in physicochemical parameters of water samples showed the results were mostly within the required regulatory requirements standards limits. The analysis showed that the water sampled in the fish ponds is suitable for fish and other aquaculture production.
