Abstract: The study is focused on the dam of Guenitra and this tributary oued Sedjane and shows the relation of the trilogy: Water, fish and concentration of heavy metals. Sampling, during the program 2002/2003, gathered the physico-chemical analysis of water and the fresh water community combined with the weather statements. The approach tests the concentrations of toxic metals in the flesh of fish and the water of 3 stations. Thus, the statistical analysis (test of Wilcoxon) treated 9 chemical variables and 7 piscicultural individuals. The results obtained confirmed that cyprinidaes retain more heavy metals: With 70 % out of zinc, 87 % out of manganese and 108% out of iron. These cyprinidaes can be recommended to cleanse, partly, the water of the reserve built on examine of iron which will be equipped with pilot hatcheries.
