“…The same characteristic was reported in carnivorous shes, such as P. pictus (Olaya et al, 2007), Glyptosternum maculatum (Xiong et al, 2011) and Paracheirodon axelrodi (Gómez et al, 2011). T. bogotensis does not have pyloric caeca, as reported in T. brasiliensis (Oliveira and Fanta, 2000) and other species of carnivorous Siluriformes, such as A. seemanni and P. blochii (Gómez et al, 2010;Guzmán et al, 2013). Most sh present a direct relationship between the length of the intestine and the feeding habit (Karachle & Stergiou, 2010).…”

“…The organs from the digestive tract of T. bogotensis showed a tissue conformation similar to that reported for other sh, with four constitutive layers: mucosa, submucosa, muscle, and serosa (Gómez et al, 2010;Gómez et al, 2011;Guzmán et al, 2013;Moawada et al, 2017;Nasruddin et al, 2014;Olaya et al, 2007). The mucosa of the mouth was composed of strati ed, non-keratinized squamous epithelium with many goblet cells, similar to that described for omnivorous Silurids such as P. pictus (Olaya et al 2007)d seemani (Gomez et al, 2010).…”

“…Lozada and Forero (1999) evaluated the stomach contents of T. bogotensis and concluded that this species includes benthic invertebrates associated or attached to muddy substrates such as dipteran larvae, chironomids, tupulids, empyids, simians, oligochaetes, trichoptera, and small amounts of macrophytic and periphytic vegetation in its diet. However, villiform teeth have also been reported in carnivorous species such as P. pictus (Olaya et al, 2007), Pimelodus cromis, Micropogonias furnieri, Menticirrhus americanus (Deli et al, 2008), and omnivorous species such as A. seemanni (Gómez et al, 2010)d blochii (Guzmán et al, 2013).…”

Trichomycterus bogotensis is one of the three species of fish that inhabit the Colombian Andes. However, several aspects of its basic biology, including its digestive system, are unknown. The morphology and histology of the digestive system are of great importance for understanding a species' feeding habits and food preferences. Thus, this study aimed to perform an anatomical and histological description of the digestive tract of T. bogotensis. The gastrointestinal tract of seven specimens was processed for paraffin histology, high-resolution optical microscopy, and transmission electron microscopy. Anatomically, T. bogotensis exhibits a terminal mouth with villiform teeth, a narrow esophagus, a large and muscular stomach, and a short intestine. Histology and ultrastructure revealed a tissue organization similar to that reported for other Silurids, composed of four layers: mucosal, submucosal, muscular, and serosa. The anatomical and histological characteristics suggest that T. bogotensis is a benthic species with a tendency to carnivory.

“…However, in the western tubenose goby, Proterorhinus semilunaris, an inverse pattern was reported (Wołczuk et al 2014). Only the anterior esophagus of H. ingens shows a large number of goblet cells secreting glycoproteins, which have been reported in other fish species (Gómez-Ramírez et al 2010, Cohen et al 2013, Guzmán-Beltran et al 2013, Nazlić et al 2014, Dos-Santos et al 2015. The posterior esophagus has a greater muscle layer.…”

The histological structure, histochemical features, and enzymatic activity of the digestive tract of juvenile Pacific seahorse (Hippocampus ingens) are described to provide information during the cultivation of this species. Serial histological sections were stained with either hematoxylin-eosin, alcian blue-PAS, toluidine blue, Sudan black, Masson's trichome, and ninhydrin-Schiff to describe the general features and the presence of glycogen, mucopolysaccharides, lipids, muscle layers, and proteins, respectively. The enterocytes height and the mucosal villi height in the esophagus and intestines were measured. Additionally, the digestive enzymes trypsin, chymotrypsin, lipase, amylase, aminopeptidase, acid phosphatase, and alkaline phosphatase activities were recorded. The esophagus showed two distinctive regions, the anterior with numerous mucous cells secreting acid mucins and the posterior with longitudinal folds and no mucous cells. The intestine was differentiated into three regions. The anterior showed goblet cells secreting acid and neutral mucins, while the middle and posterior regions presented goblet cells secreting only acid mucins. The activity of aminopeptidase, chymotrypsin, and amylase showed low levels, while the trypsin and acid phosphatase activity levels were intermediate. Lipase and alkaline phosphatase showed the highest activities. The results point that juvenile H. ingens presents a digestive structure similar to other teleost species. The high levels of lipase suggest that juvenile H. ingens have high requirements for lipids during this stage.

Con el objetivo de estudiar la anatomía macro y microscópica del sistema digestivo y los órganos anexos (hígado y páncreas) de Megaleporinus muyscorum, se sacrificaron 25 ejemplares adultos de ambos sexos, con longitud total de 32,5 cm y 339 g. Se obtuvieron cortes seriados de 5 mm mediante inclusión en parafina y teñido con hematoxilina – eosina. La boca es relativamente pequeña en posición subterminal, con dientes planos grandes y dirigidos hacia delante, las branquias son largas, separadas y definidas, el esófago y el estómago son cortos, y musculosos, este último tiene forma de “V”, y baja capacidad volumétrica. Los ciegos pilóricos son digitiformes y oscilaron entre diez y 15, el intestino es relativamente largo, con poca capacidad de distención y tres circunvoluciones. El hígado es prominente, trilobulado y parduzco, y el páncreas difuso. Histológicamente el sistema digestivo estaba constituido por cuatro capas o túnicas: mucosa, submucosa, muscular y serosa, la mucosa en el esófago estaba conformada por pliegues longitudinales y epitelio plano estratificado con abundantes células caliciformes. La submucosa presentaba tejido conectivo laxo en los tres órganos evaluados: esófago, estómago e intestino. La capa muscular del esófago está constituida por músculo estriado con orientación circular interna y externa, diferente al reportado para el estómago e intestino (músculo liso con orientación circular y longitudinal). La estructura del sistema digestivo de M. muyscorum es similar a la presentada por otros teleósteos, la posición de la boca y los dientes permiten evidenciar que es de hábito omnívoro.
