Reducing the toxicity of copper ion in common carp, cyprinus carpio by using ceratophyllum demersum

الملخص EN

Ceratophyllum demersum and the common carp fish had been exposed to three different concentrations of hydrated copper sulphate.

The copper ion concentrations in Ceratophyllum demersum tissues samples and their concentratioms in fish organ samples, before and after the treatments with the hydrated copper sulphate were recorded in 0.45 mg/L of copper ion treatment, the highest concentration was recorded in Ceratophyllum demerrsum (1147.ug/ g) then in gills (1125 μg/g) respectively while the least was in the muscles (241.0714 μg / g).

For 0.9 mg//L treatment the highest concentration was also in the tissue samples of Ceratophyllum demersum (2992.5 μg/g) as bioaccumulator, then next to it, was in the gills(642.857 μg/ g ),then in the muscles(67.5 μg/ g).

With respect to (1.8 mg/ L) treatment, the highest concentration was in Ceratophyllum demersum (5962.5 μg/g) then next to it, its concentration in gills (562.5 μg/ g) and the least one was in the muscles (44.1176 μg /g).
