Carangid fishes are commercially important in fisheries and aquaculture. They distributed worldwide both tropical subtropical marine ecosystems. Their role food webs is often unclear since their diet cannot be easily identified by traditional gut content analysis. suspected to prey on pelagic benthic species, with clupeiform being dietary items for some though it unknown whether carangids share resources or show trophic segregation. Here, we used metabarcoding overcome challenges of taxonomic approaches analyze the seven carangid species caught as bycatch Brazilian southwest Atlantic sardine fishery. Stomach contents were processed from following species:
