Nile tilapia (Orechromis niloticus) is one of the world’s most popular fresh water<br />

species that contains high protein and.essential elements. A number of 100 samples<br />

of Oreochromis niloticus were collected from the local supplier and acclimatized for 1<br />

week in a flow through tank. Samples were exposed to three different water<br />

salinities;0 ppt, 5 ppt, and 15 ppt for 2 weeks. Flesh and gills were taken from each<br />

samples and analysis for elemental composition by using inductively coupled plasma<br />

mass spectrometry (ICP-MS). Results indicated that there were no significant<br />

differences between salinities changes and elements composition for each tissue (p =<br />

2.73).<br />
