Resumo: | The work consists of knowing the aspects of the natural diet of Trichiurus lepturus since it has great commercial value for the state of Maranhão. The species analyzed came from commercial fishing, which was captured in the municipality of Raposa - MA, between January and December 2019. A total of 144 organisms were studied. The frequencies of numerical and biomass occurrence and Relative Importance Index (RII) in the diet were calculated for each prey species. As for the food items present in the species' diet, a diet was observed based on fish, unidentified items, sardines (Sardinella brasiliensis), and penaeid shrimp. The region under study can be characterized as a feeding place for the species. It has a diet composed of neritic organisms with pelagic habits associated with coastal and estuarine areas, fish item being the most specific items in the diet. It was observed that during the dry season (July to December), when biological productivity is low, feeding activity increases. The male's diet is based on fish rest, while the female's unidentified items is dominant. All immature males had their stomachs filled, and females had many unidentified items. |

Las especies analizadas provienen de la pesca comercial, la cual fue capturada en el municipio de Raposa - MA, entre enero y diciembre de 2019. Se estudiaron un total de 144 organismos. Para cada especie de presa, se calcularon las frecuencias de ocurrencia numérica y de biomasa y el Índice de Importancia Relativa (RII) en la dieta. En cuanto a los alimentos presentes en la dieta de la especie, se observó una dieta a base de pescado, elementos no identificados, sardinas (Sardinella brasiliensis) y camarones peneidos. La región en estudio se puede caracterizar como un lugar de alimentación de la especie, ya que tiene una dieta compuesta por organismos neríticos con hábitos pelágicos asociados a áreas costeras y estuarinas, siendo los peces los ítems más específicos de la dieta. Se observó que durante la época seca (julio a diciembre), cuando la productividad biológica es baja, aumenta la actividad alimentaria. La dieta del macho se basa en el reposo de los peces, mientras que la IND de la hembra es dominante. Todos los machos inmaduros tenían el estómago completamente lleno y las hembras tenían una gran cantidad de elementos no identificados (ENI).O trabalho consiste em conhecer os aspectos da dieta natural do Trichiurus lepturus, uma vez que o mesmo apresenta grande valor comercial para o estado do Maranhão.
