THE SCANNING ELECTRON MICROSCOPE OBSERVATION ON THE INTESTINE EPITHELIAL TISSUE OF THE Oreochromis aureus STEINDACHNER

The intestine epithelial tissue of the Oreochromis aureus (Steindachner) was observed with scanning electron microscope. The intestine of O. aureus (Steindachner) was divided into three parts: the front, the middle and hind. The folds of the front intestine and the middle intestine arranged in sawtooth and small wave along the direction of the intestine. The folds of the latter intestine have many strong microvillis and the shape of its goblet cell looks like a hollow. The columnar cell of the middle intestine arranged closely. The columnar cell of the latter intestine is scattered unevenly. The goblet like cell of the middle and latter intestine looks like a pit. The function of digestion and assimilation in the front is stronger than that in the middle and the hind.
