The increase in human population along with economic and technological developments has led to significant degrees of deterioration in water quality globally. As a result, it is important to determine the toxic metal concentrations in organisms living in water, especially in commonly consumed fish species. With this aim, due to the shallow water in our region we chose the important trout production location of the Çatak River for sampling in our study, using natural Salmo trutta macrostigma and Oncorhynchus mykiss from the river and Salmo trutta macrostigma and Oncorhynchus mykiss bred in a trout production facility in Çatak District. These fish had element levels (Be, B, Al, Ti, Cr, Mn, Co, Ni, Cu, Zn, Mo, Cd, Ba, Pb, Na, Mg, Si, K, Ca, Fe, As, Se, and Sb) measured in heart, muscle, liver, kidney, gills, gonads, brain, and intestinal tissue using an ICP-OES device. The results of the study are grouped as toxic (Be, Cd, Pb, Al, Ba, Ti), trace (Fe, Zn, Cu, Mn, Co, Ni, Cr, B, Si, Mo) and macro (Ca, Mg, K, Na) elements for assessment. As a result, the nutrient values of the trout grown on the farm and in the natural environment were high.
