Abstract
The objective of this paper was to study anatomy and histology of pyloric caeca in 2 years old beluga (Huso huso (Linnaeus, 1758)). In this study 12, 2-year old male and female H. huso were included. Anatomical position of pyloric caeca was studied through dissection. Histological specimens were fixed in 10% formalin buffer phosphate for 72 h. The specimens were processed through paraffin embedding and 7 micrometer sections were cut and stained by Hematoxylin and eosin and observed under light microscope. It was shown that pyloric caeca in H. huso were attached and formed a large mass between stomach and duodenum. The capsule was a smooth muscle that had dispatched trabeculae into the organ and formed lobules. There were numerous villi with simple columnar epithelium in different sizes in each lobule. It was demonstrated that pyloric caeca in H. huso like other sturgeon fish were attached to each other and formed an organ called pyloric caeca with a long leaf-shaped villi.
