The effect of copper, zinc, mercury and cadmium on some sperm enzyme activities in the common carp (Cyprinus carpio L.).

چکیده
The objective of the study was to determine the effect of copper, zinc, cadmium and mercury ions (100, 10 and 1 mg/l) on the activity of some enzymes of carp spermatozoa. Acid phosphatase activity was proved to be relatively insensitive to zinc ions, while copper, mercury and cadmium ions effectively inhibited the activity of this enzyme. Beta-N-acetylglucosaminidase activity was sensitive only to mercury ions. Lactic dehydrogenase activity remained unaffected by heavy metals. Our results showed that, among the examined metals, mercury had the strongest inhibitory effect on enzymatic activities.

The aim of this study was to evaluate the effects of different doses of magnesium-oxide nanoparticles (nano-Mg) on the growth performance, digestive enzyme activities, and some innate immune parameters in common carp fingerling (Cyprinus carpio). Nano-Mg was added to the experimental basal diets at the rates of 0 (control), 25, 50 and 100 mg/kg. Four groups of fish with an average weight of 12....
