RESUMENEl presente estudio hace un análisis del patrón anatómico e histológico del sistema digestivo de la sabaleta (Brycon henni). Fueron capturados seis individuos machos y hembras adultos en la quebrada Guaracú, Antioquia, Colombia, entre mayo y junio de 2016. Los peces pesaron 151.2 g y midieron 22.7 cm de longitud total. Los órganos del aparato digestivo fueron fijados en formol buferado al 10% y procesados con técnicas histológicas de rutina. Las estructuras más resaltantes, debido a su patrón anatómico específico y complejidad histológica fuero las branquiespinas (4), los ciegos pilóricos (13 en hembras y 8 en machos), el hepato-páncreas voluminoso y lobulado, y el intestino anterior, medio y posterior con vellosidades y microvellosidades. La sabaleta, según el patrón digestivo en cuanto a la clase de dientes, branquiespinas, estómago, longitud y estructura intestinal, sugiere que es una especie de hábito alimenticio omnívoro, pero con tendencia carnívora. ABSTRACTThe present study describes the anatomical and histological pattern of the digestive system of the 'sabaleta' (Brycon henni). Six adult male and female individuals were fished in Guaracu creek, Antioquia, Colombia, between May and June 2016. The fish weighed 151.2 g and were 22.7 cm in total length. The organs of the digestive system were fixed in Rev Inv Vet Perú 2017; 28(3): 490-504Descripción anatómica e histológica del aparato digestivo de la sabaleta 10% buffered formalin and processed with routine histological techniques. The most remarkable structures, due to their specific anatomical pattern and histological complexity, were the gill rakers (4), the pyloric caeca (13 in females and 8 in males), the bulky and lobate hepato-pancreas, and the anterior, middle and posterior intestine with villi and microvilli. The 'sabaleta', according to the digestive pattern as to teeth, gill rakers, stomach, and intestinal structure and length, suggests that it is a kind of omnivorous food habit species, but with a carnivorous tendency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
