Abstract

Forty LARVAE from the first day to three weeks post hatch for investigating the development of PYLORUS and PYLORIC CAECUM in larval stages of Acipenser stellatus were prepared. The LARVAE were collected randomly and immediately were fixed in Buin's fluid. After providing the samples, some sections at 6 micrometers were prepared, stained with hematoxylin and eosin and studied microscopically.The results showed that in the first day after hatch the abdominal cavity was filled with yolk. In the first week, PYLORUS with a thick musculature is apparent. The luminal surface of PYLORUS was lined with a simple columnar epithelium devoid of any secretory cells. PYLORIC CAECUM has some short villi with simple columnar epithelium possessing some cytoplasmic vacuoles. Until the second week, PYLORIC CAECUM is pyramidal and its mucosal epithelium is simple columnar with cytoplasmic vacuoles. Up to the end of third week, the PYLORUS possesses some mucosal plicae with simple columnar epithelium with the least cytoplasmic vacuoles. At this time the luminal surface of caecum shows tall leaf shape villi with a simple columnar epithelium in which a few secretory cells is observed gradually. In caecum as well as PYLORUS the cytoplasmic vacuoles decrease and then disappear.
