The Effect of Magnetized Water on Some Essential Mineral Content of Nile Tilapia Fish (Oreochromis Niloticus)

Twenty samples of Nile tilapia fishes were exposed to three treatments, treatment one with non-magnetized water treatment two with magnetized water (twice) and treatment three with magnetized water (three times). Some macro and micro-nutrients were determined in the samples using Atomic Absorption Spectrometer (AAS) and flame photometer. The results showed significant differences between treat-ments and the higher concentration was observed in treatments with magnetized water. The concentration of minerals determined were within FAO mean concentration ranges for fish.
