| Abstract: | The present work was carried out on ten mature Tilapia (Tilapia spilurus) and ten mature
Bream fish (Mylio cuvieri) and the specimens were processed for histological studies.
The oesophagus of Bream fish is characterized by the presence of numerous mucous
cells which react positively to P.A.S. and alcian blue.
While oesophagus of Tilapia is completely filled with mucous cells that react positively
to P.A.S. only.
The stomach of Bream consists of one part while that of Tilapia consists of two parts
(cardiac and pyloric). The mucosa of stomach of both types of fish reacted positively to
P.A.S. the pyloric caeci of Bream fish showed numerous mucous cells that react positively
to Alsain blue.
The small intestine of bream has thicker tunica muscularis than that of same layer in
small intestine of Tilapia. |
