Comparative Histomorphological and Histochemical Studies on the Oesophagus of Nile Tilapia <i>Oreochromis niloticus</i> and African Catfish <i>Clarias gariepinus</i>

<div>Photomicrographs of the esophagus in Nile tilapia (a) showing strong positive alcianophilic granules in the mucous secreting cells of the stratified epithelium lining the mucosal folds and moderate reaction in the propria-submucosa. In African catfish (b) showing moderate alcianophilic reaction in the mucous cells and negative reaction in the underlying lamina propria-submucosa. Alcian blue, ×100.</div>
