Resumo: | Abstract Bathygobius soporator (Valenciennes, 1837) is one of the most common fishes in tide pools in the estuary of Pará state, and has an omnivorous feeding habit. This study examined the diet of the species in Maiandeua Island, and aimed to: (i) describe the diet of B. soporator through indexes based on the occurrence and weight of consumed items; and (ii) evaluate if there is variation in diet composition between males and females. Frequency of Occurrence, frequency of weight and Alimentary Index were calculated for each item, and differences in the diet composition of males and females were observed through multivariate analyses (ANOSIM, NMDS and SIMPER). Bathygobius soporator presented carnivorous feeding habit, eating mainly crustaceans, and differences among males and females were observed, males consuming smaller amounts of crustaceans and including algae in their diet.
