Plastics in the marine and estuarine ecosystems are one of the factors that can affect de trophic niche of fish community. This kind of marine litter have been disposed in the costal areas and can reach to many fish nursery areas, as beach surf zone, mangroves and estuarine main channel. Once in theses areas, fragments are mistakable as “prey”, ingested by the ichthyofauna and transferred along the chain. Based on this, the aim of this study was to investigate the feed ecology of Larimus breviceps, along his history life, at the surf zone of a beach adjacent to an estuary mouth in northeast, Brazil. Fishes were sampled from April 2019 to February 2020, using a beach seine net (5 mm mesh-size). Than, were classed into ontogenetic stages (juveniles, subadults and adults), had stomachs analyzed, and preys identified and quantified as relative importance (%IRI). 83 fishes were sampled. 14 type of preys were identified. The most important preys were, copepods, amphipods, mysis larvae, vegetal material and microplastics, respectively. For ingestion of theses preys, ANOVA found differences (p
