DETERMINATION OF SOME PHYSICOCHEMICAL PARAMETERS OF WATER FROM ARTIFICIAL CONCRETE FISH PONDS IN ABRAKA AND ITS ENVIRONS, DELTA STATE, NIGERIA
This work studied some physicochemical parameters of water from artificial concrete fish ponds in Abraka and its environs with a view of finding the fitness of the water environment for fish farming. Water samples were collected according to standard methods. pH, and temperature were determined in-situ while the other properties were determined out-situ. All determinations were carried out according to standard approved methods. The mean and standard deviation of results obtained are as follows: pH (7.03±0.06), conductivity (15.88±1.96μS/cm), Temperature (26.73±1.730C), DO(10.11±0.63mg/L), BOD(3.02±0.77mg/L), TDS(22.11±2.4 mg/L), TSS(87.97±9.63mg/L), Turbidity (9.23±1.63NTU), Total hardness (4.91±0.90mg/L), Acidity (87.90±5.62mg/L), alkalinity (37.67±06.19 mg/L), phosphate (1.41±0.45mg/L), chloride (8.60±1.53mg/L), nitrate (3.81±0.55mg/L), sulphate (3.71±1.00 mg/L), Magnesium (1.16±0.15 mg/L), calcium (0.42±0.27mg/L), potassium (11.74±2.01 mg/L). These results were largely within the WHO, SON and FEPA limits for drinking water. They were also within the recommended values for optimal survival for fish in ponds. The implications are that the water sampled in the various ponds studies are fit for fish production as well as fit for irrigation purpose.
