Abstract :
Argyrosomidae family and the species Argyrosomus hololepidotus due to high valued protein are among the most valuable aquatics in the Persian Gulf, Oman Sea and the coasts of Khuzestan. Lymphoid tissues are of the most important tissues in fish which their identification is important in health and disease states. Unlike mammals, fish lack lymph node and also there is not hematopoietic tissue in their bone marrows, and so mainly Hematopoiesis is done in their spleen and kidney. In this study, 6 pieces of Argyrosomus hololepidotus were provided from the Persian Gulf. Some samples from the spleen up to 5mm thickness were prepared and fixed in 10% buffered formalin. Then tissue sections were prepared in 5-6 μ and after HandE staining, the structures of the capsule and parenchyma of pronephrose were studied histologically. In order to confirm the results and findings of this staining, silver staining was also used. Microscopic results showed that tissue structure of Argyrosomus hololepidotuspronephrose was consisted of hematopoietic tissue, lymphoid tissues and kidney tubules. Pronephrose lymphoid tissues are also consisted of reticular supportive tissue and lymphocytic parenchyma cells.
