Abstract

The aim of this study was to investigate the morphologic and microscopic features of spleen as the important lymphatic organ on immune system of Mystus vittatus were recognized. A total of 60 adult fishes of both sexes, weighing 42-45 g (standard length 12-15 cm) collected from Vellar estuary, Parangipettai, Tamilnadu. After removing the spleen, it was immediately fixed in Bouin’s solution and transport to the laboratory. The 5-6 µm sections were made using paraffin embedding techniques and stained by Haematoxylin and Eosin. The spleen as an elongated organ located on the middle part of digestive canal and microscopically was covered by a capsule of connective tissue and an epithelial layer. Spleen included white and red pulps. There are some similarities and some differences between spleen of this species and mammals. Spleen as the biggest and the most important lymphatic organ and microscopically very similar to spleen of mammals has many functions such as lymphatic cell production. Histomorphology of spleen shows that in M. vittatus is organized inside spleen and like some fishes, splenopancreas structure is present.
