In various fish ponds, metal concentrations in the carp muscle tissue varied depending on the metal type. Between compared fish ponds, there were significant differences （P 〈 0.01） in the concentration in muscle carp tissue, except for cadmium. Metal concentrations in the pike muscle tissue also varied among fish ponds, depending on the type of metal. In all compared cases, there were significant differences between metal concentration in pike muscle tissue （P 〈 0.01）. Lead and cadmium concentration in pike muscle tissue were significantly higher （P 〈 0.01, P 〈 0.05, respectively）, and mercury and arsenic concentration were significantly lower （P 〈 0.01） than concentration of this heavy metals in carp muscle tissue in all comapered fish ponds. The results obtained in this study indicate variation in a range of examined metal concentration in muscle tissue, which seems to be typical for the Serbian fish ponds, but is lower than those in rivers with considerable anthropogenic impact.展开更多
