The gut contents of juvenile Citharichthys spilopterus, Symphurus plagiusa, and Gobionellus boleosoma from a Louisiana estuary were quantified. Juveniles from 10–49 mm standard length (SL) fed on different components of meiofauna or zooplankton, and only one species, C. spilopterus, exhibited a clear ontogenetic feeding shift to larger prey. C. spilopterus up to about 30 mm SL fed primarily on zooplanktonic copepods and then mysid shrimp became the dominant prey. S. plagiusa fed primarily on epibenthic/hyperbenthic harpacticoid copepods, and G. boleosoma fed mostly on meiofauna, primarily benthic harpacticoids.
