Resumo: The digestive tube of Colossoma macropomum, popularly known as tambaqui, was described by anatomic, histologic, histochemical and ultrastructural studies. Fragments of the esophagus, stomach and intestines were used for morphological and histochemical routine assays in mucosubstances. The C. macropomum has a short esophagus, a U-shaped syphon stomach with thick longitudinal folds and an intestine with circular folds related to an increase in time retention of food. Pyloric caeca were also reported in the intestine, associated with digestion and increase of the absorption surface. The esophagus showed a stratified epithelium composed of epithelial cells with fingerprint-like microridges on the cellular surface and goblet cells with cytoplasm filled with secretion granules composed of neutral and acid mucosubstances. The stomach was divided into the glandular cardic and fundic regions and aglandular pyloric region with pyloric sphincter. The lining gastric epithelium was simple columnar with apical mucosubstances that protects the mucosa. The intestine has a simple columnar epithelium mainly composed of enterocytes with apical microvillis and goblet cells that increased in number in the aboral direction. Goblet cells had secretion granules for protection, lubrication and transformation of food in chyme. Rodlet cells were also reported in the intestinal epithelium associated with the immune system of teleosts. The results correlated the morphofunctional characteristics of the digestive tube of C. macropomum with other species with different feeding habits, contributing to the development of nutritional studies for the improvement of Brazilian fish culture

Fragmentos de esôfago, estômago e intestino foram destinados para rotinas morfológicas e histoquímicas de mucossubstâncias. Esta espécie apresentou esôfago curto, estômago sifonal em U com pregas longitudinais espessas e intestino com pregas circulares relacionadas ao aumento do tempo de retenção do alimento. Cecos pilóricos também foram observados no intestino, associados à digestão e aumento da superfície de absorção. O esôfago apresentou epitélio estratificado pavimentoso, composto por células epiteliais com microssaliências digitiformes na superfície e células caliciformes com citoplasma repleto de grânulos de secreção, composto por mucossubstâncias neutras e ácidas. O estômago foi dividido em regiões cárdica e fúndica glandulares e região pilórica aglandular com presença de esfíncter pilórico. O epitélio de revestimento gástrico apresentou-se simples colunar com mucossubstâncias apicais que protegem a mucosa. O intestino apresentou epitélio simples colunar composto principalmente por enterócitos com microvilosidades apicais e células caliciformes que aumentaram em número na direção aboral. As células caliciformes mostraram grânulos de secreção, importantes para proteção, lubrificação e transformação do alimento em quimo. Ainda, observou-se células rodlet no epitélio intestinal associadas ao sistema imune de teleósteos. Os resultados apresentados possibilitaram correlacionar as características morfofuncionais do tubo digestivo de C. macropomum com outras espécies de diferentes hábitos alimentares, contribuindo para o desenvolvimento de estudos nutricionais, essenciais para a melhoria da piscicultura nacionalCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista (Unesp)Vicentini, Carlos Alberto [UNESP]Universidade Estadual Paulista (Unesp)Mori, Ricardo Hideo [UNESP]2016-08-16T13:05:02Z2016-08-16T13:05:02Z2016-01-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesis68 f. : il.application/pdfapplication/pdfMORI, Ricardo Hideo.
