 Studies in the Gulf of Carpentaria and in particular, Albatross Bay, indicate the species is most common over known prawn grounds.A shift in diet happens with age, with young fish less than 275 mm in length taking penaeids, brachyurans, other crustaceans, echinoderms, and molluscs, while larger fish take mostly small fish.The smaller trevally tend to forage during the day, taking species of small noncommercial species of prawns, while the larger fish took larger, commercially important species at night.
