Sažetak
The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described. The digestive tract of pike and catfish is short in accordance with their predatory nature and consists of oesophagus, stomach and intestine. The oesophagus is short with longitudinal folds. The mucosa of pike oesophagus is stratified and contains two types of mucous cells: in contrast to catfish oesophagus there is only one type of mucous cells. The stomach is an elon-gated sac-like structure with glands in lamina propria. In pike the gastric glands are simple tubular but in catfish they are branched tubular and surrounded by connective tissue. The intestines in both fishes are short with many intestinal villi. Many goblet cells are situated between superficial epithelial cells.
