The fish measured, on average, 11.8 - 18 (15.1 ?? 1.35) cm of standard length and weighed 30.1 - 71.0 (47 ?? 10.66) g. For the parasitological studies 38 fish were examined and 31 were parasitized. Eighty-eight specimens of Nematoda were collected: 53 Procamallanus (Spirocamallanus) inopinatus larvae L4 and adults in the intestine and stomach; 18 Spinitectus rodolphiheringi larvae L3, L4 and adults in the intestine and stomach, and 17 Contracaecum sp. larvae L3 in the stomach. For the anatomical and histological studies, six A. nuchalis were used. The morphological, anatomical and histological characteristics showed that the structure and arrangement of the digestive tract of A. nuchalis is in accordance with the general basic pattern described for the other teleost fishes. It was observed the division into: buccopharyngeal cavity, esophagus, stomach and intestine and, histologically, the wall of the tube consists of the mucosa, submucosa, muscular and serous layers. The attachment of Nematoda species to the digestive tract of A. nuchalis did not cause aggressive or even visible mechanical lesions along the evaluated mucosa. Foram capturados 44 Auchenipterus nuchalis, em quatro expedi????es, nos meses de setembro, outubro, novembro e dezembro de 2018, no complexo de lagos do Catal??o no munic??pio de Iranduba, Amazonas, margem esquerda do rio Solim??es e direita do rio Negro. Os peixes mediam, em m??dia, 11,8 - 18 (15,1 ?? 1,35) cm de comprimento padr??o e pesavam 30,1 ??? 71,0 (47 ?? 10,66) g. Para os estudos parasitol??gicos foram examinados 38 peixes e 31 estavam parasitados. Foram coletados 88 esp??cimes de Nematoda: 53 Procamallanus (Spirocamallanus) inopinatus larvas L4 e adultos no intestino e est??mago; 18 Spinitectus rodolphiheringi larvas L3, L4 e adultos no intestino e est??mago, e 17 Contracaecum sp. larvas L3 no est??mago. Para os estudos anat??micos e histol??gicos foram utilizados seis A. nuchalis. As caracter??sticas morfol??gicas, anat??micas e histol??gicas mostraram que a estrutura e disposi????o do tubo digestivo, de A. nuchalis encontra-se de acordo com o padr??o geral b??sico descrito para os demais peixes tele??steos. Foi observado a divis??o em: cavidade bucofar??ngea, es??fago, est??mago e intestino e, histologicamente, a parede do tubo ?? constitu??da pelas camadas mucosa, submucosa, muscular e serosa. A fixa????o das esp??cies de Nematoda, no tubo digestivo de A. nuchalis, n??o causou les??es mec??nicas agressivas ou mesmo vis??veis ao longo da mucosa avaliada.
