 In this location, it was found bay whiting predominantly prey on a variety of shrimp species, polychaete worms and Mantis shrimp, with minor amounts of crabs, sea urchins, bivalves and copepods.Unlike other species of sillaginid, the bay whiting doesn't have a large dietary shift as it moves to adulthood, causing parents to compete with offspring to an extent.The diet is, however, offset from the co-occurring "S. sihama", preventing significant competition from this species.
