The fine structure of the intestinal epithelium of Tilapia grahami.

Abstract

The ultrastructure of the intestinal epithelium is described in Tilapia grahami. The intestine is divisible into cranial, middle and caudal portions. The cranial intestine is involved in water anp ion transport as well as in lipid absorption. The caudal intestine is important in protein digestion and adsorption. There is likely to be some functional overlap in the intermediate middle intestine.
