Experimental studies on the effect of cadmium chloride, zinc acetate, their mixture and the mitigation with vitamin C supplementation on hatchability, size and quality of newly hatched larvae of common carp, Cyprinus carpio

The present results show that the fertilization and hatching rates, as well as the development of the embryos of common carp are adversely affected by heavy metal pollution. The degree of this effect depends on the duration and the concentration of the heavy metal used. Malformation of the yolk sac...

Description
Summary:The present results show that the fertilization and hatching rates, as well as the development of the embryos of common carp are adversely affected by heavy metal pollution. The degree of this effect depends on the duration and the concentration of the heavy metal used. Malformation of the yolk sac and curvature in the abdominal region were also observed throughout this study. No statistical difference was recorded between the polluted group which was supplemented with vitamin C (300mg/kg of dry feed), and the control group (P
