“…Albrecht et al (2001) reported submucosa with thick layer of adipose tissue in L. friderici and L. taeniofasciatus, but no similar histological structure was observed in this study. The mucosa folds in the intestine epithelium were abundant in present study, especially in the anterior part, with aid to elevate of the mucosa area for absorptive role, which indicating the anterior intestine was the main site of digestion and absorption of nutrients, a common feature among carnivorous teleosts (Rodrigues et al 2009). Observations at ultrastructural level showed that three types of cells (mucous, glandular and endocrine cells) were found in the stomach epithelium.…”

2011. A study of morphology and histology of the alimentary tract of Glyptosternum maculatum (Sisoridae, Siluriformes). -Acta Zoologica (Stockholm) 92: 161-169.The structure of alimentary tract has been studied in a cold water fish Glyptosternum maculatum, an endemic teleost species of notable economic importance and with high potential for controlled rearing of the species in Tibet, by light and electron microscope. Glyptosternum maculatum has short oesophagus, large caecal-type stomach and short intestine, and the digestive tract with four layers: mucosa, submucosa, muscularis and serosa. Taste buds were found in the epithelium of lips, buccopharynx and oesophagus. The stratified epithelium of buccopharynx and oesophagus was located with numerous goblet cells. The U-shaped stomach has three parts, corresponding to mammalian cardiac, fundus and pyloric portion, lined with a single-layered columnar epithelium, and tubular gastric glands are present in cardiac and fundic portion, but absent in pyloric portion. No pyloric caeca was detected. The intestine is separated from the stomach by a loop valve. The intestine epithelium is composed of simple columnar cells with a distinct microvillus brush border and many goblet cells. Meanwhile, the intestinal coefficient was 0.898. At the ultrastuctural level, three type cells (mucous, glandular and endocrine cell) were found in the stomach, and glandular cell with a great amount of pepsinogen granules. The enterocytes of the intestinal mucosa display abundant endoplasmic reticulum, mitochondria and well-developed microvilli.

“…On the other hand, the intestinal coefficient of pacamã was higher than that of other carnivorous Siluriformes. In Pseudoplatystoma fasciatum , the coefficient ranges from 0.68 to 0.84 (Rodrigues et al., ) and in G. maculatum , the coefficient is 0.89 (Xiong et al., ). Another thirteen carnivorous teleosts studied by Carrassón and Matallanas () showed an intestinal coefficient lower than that of pacamã, ranging from 0.27 to 0.90.…”

Morphological characterisation of the digestive tract of the catfish Lophiosilurus alexandri Steindachner, 1876 (Siluriformes, Pseudopimelodidae)

The anatomical arrangement of the digestive tract and the length (cm) of the oesophagus and intestine of the catfish Lophiosilurus alexandri were described, and the intestinal coefficient was determined. L. alexandri oesophagus is short, in median position, and presents longitudinally folded mucosa, whilst its epithelium is stratified and non-keratinised, with mucous, claviform and epithelial cells. Stomach has "C" shape, with folded mucosa along cardiac region, disordered in the fundic region, and directed to the sphincter in the pyloric region. Its epithelium is simple prismatic, and cardiac and fundic portions have gastric glands. Cranial intestine is formed by pyloric flexure and descending loop attached to the right side of stomach. Middle intestine is winding and positioned to the right of caudal portion of stomach. Caudal intestine is linear and with a median position up to the anus. Intestinal coefficient was 1.39 ± 0.30 cm. Epithelium is simple prismatic with brush border and contains epithelial and goblet cells. Caudal region has highest concentration of goblet cells. Were detected neutral glycoproteins, carboxylated and sulphated acid glycoconjugates for mucous cells and goblet cells, and neutral glycoproteins for the apical region of gastric epithelial cells. Morphological features could be related to piscivorous species feeding habit. K E Y W O R D S catfish, intestinal coefficient, mucosa morphometry, mucosubstances

“…For those authors, the use of CO alone is not enough to determine the specialisation degree within a given diet, although Kapoor et al (1975) reported that the intestine length naturally responds to changes in the nutritional conditions and the development stages. The intestine's epithelium of S. knerii is simple and of a prismatic type with goblet cells, as observed in Pseudoplatystoma fasciatum (Rodrigues et al 2009) and Glyptosternun maculatum (Xiong et al 2011). Goblet cells are common in the intestinal mucosa of fish (Kapoor et al 1975) and they have been reported in recent studies as producing mucosubstances (Xiong et al 2011, Løkka et al 2013.…”

The digestive tracts of 44 specimens of Schizodon knerii were studied using anatomical, histological and histochemical techniques. The mouth has terminal position, the lip epithelium is squamous stratified with mucous, claviform cells and taste buds, teeth have an incisive form and the tongue has a stratified squamous epithelium with mucous cells and taste buds. The oropharynx cavity is formed by gill apparatus and pharyngeal teeth. The oesophagus presented pleated mucosa, a stratified squamous epithelium with mucous cells, oesophageal glands and taste buds. The stomach presented cardiac, fundic and pyloric regions, simple prismatic epithelium with tubular glands, with none in the pyloric region. The intestine contains 11-15 pyloric caeca, a simple prismatic epithelium with brush border, goblet cells and lymphocytes. Mucosal cells, oesophageal glands and goblet cells reacted positively to PAS, amylase + PAS, Ab pH 2.5 and Ab pH 0.5. Gastric prismatic cells reacted positively to PAS, amylase + PAS, but only those in the pyloric region reacted positively to Ab pH 2.5 and Ab pH 0.5. The results improve the understanding of the anatomy of S. knerii feeding habits and the presence of mucosubstances in the epithelium, highlights the importance of glycoproteins for passing food through the digestive tract.
