Laboratory experiments on larval white seabass, Atractoscion nobilis , showed that first feeding success on mixed zooplankton was zero, and less than 5% on Artemia nauplii , for larvae of different sizes. Experience increased success from 20% after 2 days to 69% after 14 days when larvae fed on Artemia nauplii , and to 42% after 4 days of feeding on zooplankton. This increase was attributed to learning in larvae less than 5·0 mm s.l. , and in part to size‐related factors in larvae greater than 5·0 mm s.l.
