Abstract

There is no doubt that Mercury is considered one of the significant pollutants to the environment. It have

been noticed that exists in three forms. The previously mentioned forms are elementalor metallic (mercury),

organic and inorganic mercury. Inorganic mercury can be converted microbiogically into organic form.

The present paper has been focused on the genotoxicity and histopathological effect of mercuric chloride

on Ctenopharyngodonidella (Grass carp). Basically, Ctenopharyngodonidella is one of the most important

fish species according to FAO reports. Moreover, C. idella fry have been divided into four groups. The

first Group was exposed to sublethal concentrations of 5 ppb, Second Group was exposed to 10 ppb of

mercuric chloride and the third one was exposed to 15 ppb, on the other hand,the fourth Group was kept

as unexposed control. Furthermore,A blood smear was done for micronuclei examination and gills and

liver of the tested fish were obtained for histopathological study.A significant increase of micronucleus

notched erythrocytes in fish exposure with HgCl2 than in the controls). The microscopic examination has

shown different histological changes in the organs of the examined fish which has been exposed to mercuric

chloride in comparison with control organs.
