Waters can be polluted by heavy metals which are accumulated and concentrated fish ; therefore they show the degree of environmental pollution. The aim this paper was to determine concentrations in water, mud organs, whether these allowed accordance with normative provisions and, considering pollution metals, if meat is hygienically safe food animal origin. Concentrations (lead, chromium, manganese, iron, copper, zinc) were determined different organs (liver, kidney, intestine, milt skin + muscle) pike (Esox lucius) European catfish (Silurus glanis) Energy Dispersive X – Ray Fluorescence Method (EDXRF). Statistically significant difference between water (p< 0.05), as well 0.05). obtained results that highest liver, lowest ones muscle, i.e. edible parts. In Union Republic Croatia, values lower than maximally muscle. When taken into account, it indicates researched
