Alkaline and acid phosphatase in the digestive system of two teleost fishes.
Alkaline and acid phosphatases are distributed in the stomach, intestine, liver and pancreas of Heteropneustes fossilis and Cirrhinus reba. In oesophagus and rectum they are found in traces only. In the stomach of Heteropneustes, the phosphatases are confined to the mucosa and gastric glands. In the omnivorous fish, Heteropneustes the intestine is shorter and the activity of the enzymes is higher where as in the herbivorous form Cirrhinus with long and coiled intestine, the enzymes are comparatively weak and distributed from the intestinal bulb to the posterior portion of the intestine. In Heteropneustes the enzymes are concentrated in the duodenum and anterior region of the intestine only. This regional difference in the distribution pattern may be correlated to the site of absorption of the metabolites.
