“…Similar to observations in pirarucu, the predominance of neutral mucins and the low occurrence of acidic mucins in the gastric epithelium (Reifel & Travill, 1978;Ostos Garrido et al;Carrassón et al, 2006;Faccioli et al) as well as the combined production of both (Ostos Garrido et al) were reported in other fish species.…”

“…The division into corpus (proximal and glandular region) and pylorus (distal and aglandular region) has also been used for other fish species (Reifel & Travill, 1978;Ostos Garrido et al, 1996). The large stomach volume of pirarucu and the presence of deep, longitudinal folds and a fairly developed tunica muscularis aid stomach distension and the storage of large food quantities (Rodrigues & Menin).…”

of the pirarucu (Arapaima gigas) digestive tract. Int. J. Morphol., 35(3):950-957, 2017. SUMMARY:The present study describes the morphology and histology of the digestive tract of juvenile pirarucu, which is a Neotropical fish species with great potential for aquaculture in the Amazon region. Three size classes of pirarucu juveniles from commercial fish farms were sampled for histological examination of the oesophagus, stomach, pyloric caeca, intestine and liver. The morphological and histological features of the pirarucu digestive tract are similar to other carnivorous teleosts and enable the species to ingest, store and digest large food items. Acidic and neutral mucins are secreted by the mucosa of the oesophagus, stomach, pyloric caeca and intestine to protect the mucosal epithelium and to lubricate and facilitate food passage along the digestive tract. Complex transverse folds are predominant in the intestinal mucosa and most likely contribute to optimization of the digestion and nutrient absorption processes, thereby offsetting the relatively short length of the intestine. The exocrine pancreas appears diffuse in the liver and mesentery around the pyloric region of the stomach, pyloric caeca and initial part of the intestine. The digestive tract morphology and thickness become increasingly developed with the size of pirarucu.

he present investigation aims to illustrate the morphological, histological and ultrastructural differences in the intestine of a carnivorous fish, Schilbe mystus and a herbivorous fish, Labeo niloticus, in correlation with their feeding habits. The histological examination of the mucosa of the intestine of both studied species revealed that it is built up of a simple columnar epithelium that contains goblet cells. Though these, are generally more numerous in the intestine of Schilbe mystus than in that of Labeo niloticus. The ultrastructural investigation of the mucosa of the duodenum and ileum of Schilbe mystus revealed that the enterocytes are tall columnar cells and possess well-developed microvilli, numerous mitochondria, microtubules and numerous lipid droplets. The ultrastructural examination of the mucosa of the ileum of Labeo niloticus revealed that the enterocytes are tall columnar and possess well-developed microvilli, numerous mitochondria, microtubules, a few endocytotic channels and aggregated chylomicrons. The enterocytes of the rectum of both studied species are tall columnar and are characterized by the presence of short and wellspaced microvilli, a well-developed vesiculotubular system, numerous microtubules and mitochondria. In addition, the rectal enterocytes of Schilbe mystus contain endocytotic vesicles. The intestinal muscularis of both studied species is well-developed and built up of unstriated muscle fibres, which are arranged into two layers: an inner circular layer and an outer longitudinal one. The rectal muscularis of both studied species is thicker than that of the rest of the intestine.

“…In contrast, the stomach of fish and other non-mammalian vertebrates have only one cell type, appropriately referred to as oxynticopeptic (oxyntopeptic) cells, to accomplish both functions. Oxynticopeptic cells contain abundant zymogen granules (Garrido et al, 1993) or large intracellular vacuoles (Bomgren et al, 1998) or cavities (Garrido et al, 1996) and secrete both hydrochloric acid and protein. Oxynticopeptic cells are located mainly in the corpus of the stomach and are embedded in glands within the lamina propria as described in the winter flounder, European eel, rainbow trout and Atlantic stingray (Garrido et al, 1996;Garrido et al, 1993;Gawlicka et al, 2001;Smolka et al, 1994).…”

Because oxynticopeptic cells are not specialized, they are thought to be less efficient in secreting acid than mammalian parietal cells (Koelz, 1992;Vial and Garrido, 1979).…”

+/bicarbonate cotransporter (NBC), and had no effect on gastrin-like mRNA and somastostatin (SST) mRNA abundance. Gastrin-like mRNA and SST-2 mRNA were equally distributed between corpus and antrum. ATP4A mRNA and NBC mRNA were in the corpus, whereas SST-1 mRNA was in the antrum. Trout gastrin-like EST had modest homology to halibut and pufferfish gastrin, whereas trout ATP4A mRNA had у у95% amino acid homology with mammalian, Xenopus and flounder ATP4A. Although ATP4A seems highly conserved among vertebrates, gastric acidity is much less in trout than in rats, explaining the low digestibility of bone phosphorus, abundant in fish diets. Dietary acidification does not reduce acidity enough to markedly improve phosphorus digestibility, perhaps because exogenous acids may inhibit endogenous acid production.
