To study the effects of mercuric chloride on kidney and intestine tissue of Persian Sturgeon,
Acipenser persicus fry, fish exposed freshwater contain 15 ppb of mercuric chloride and control group
were kept in non polluted freshwater for 48 hours. Histological studies of the processed tissues
showed marked histological alterations than the control group that exposed only to freshwater. The
pathologic lesions of the kidney included severely epithelial cell necrosis, lesion of epithelial cells
from the basement membrane in the proximal and distal tubules. Proximal tubule also showed
inflammation and incorporation of brush borders. Decrease of lymphoid and hematopoietic tissue
observed. Pathologic lesions of intestine tissue were showed the epithelial necrosis, shrinkages of
secretory follicule, lesion of epithelial microvilli in intestine. Results showed that low concentration
of mercuric chloride can pose undesirable alternation in Persian Sturgeon fry, an economic and
endangered species of the Caspian Sea.
