RESUMO:

Hypostomus paparie is a fish belonging to the Siluriformes order, Loricariidae Family, inhabiting neotropical regions. Within the neotropical region, there is a semi-arid region, characterized by strong sunlight, high temperatures, scarce, irregular rainfall, and short precipitation periods. Another particularity of semi-arid waters is their use for leisure activities, fishing, agriculture, livestock, water supply for cities, and electricity production. These characteristics lead some rivers to have hypoxic waters at certain times of the year. Throughout evolution, some fish species developed adaptations to survive in this kind of environment, such as using part of the digestive system
for facultative air breathing. The objective of this work is to characterize the digestive system of H. paparie in order to contribute to research related to understanding the anatomy and ecology of thesee species. For the methodology, 10 specimens were used, collected from the Apodi-Mossoró river, a stretch where the Santa Cruz dam is located, in Apodi city. The animals were taken to the laboratory for the preparation of histological slides. After the analyses, pictures were taken with the aid of a photomicroscope. The analyzes showed that H. paparie starts its digestion in the esophagus, with more intensity in the intestine. The stomach has a dual function, digestion, and respiration, with digestion being more prominent in the cardiac region and respiration in the pyloric region. The intestine front part also does breathing work in addition to digestion. The middle and posterior region was characterized by their digestive activity.
