GLYCOHISTOCHEMISTRY OF THE TILAPIA SPP STOMACH

A histochemical study using conventional and lectin methods was perfor med on the stomach of fasting and feeding adults of Tilapia spp. A bat tery of HRP-conjugated lectins combined with exoglycosidase digestion was used. The differences found in the epithelium, gastric pits and ga stric glands between fasting and feeding subjects were related to the functional stages of the organ. Carbohydrate composition was also comp ared with that of mammals and birds. (C) 1996 The Fisheries Society of the British Isles
