title: Seasonal and ontogenetic diet shift in juvenile stone flounder Platichthys bicoloratus.
abstract: The diet of juvenile (0 year old) stone flounder Platichthys bicoloratus after settlement was investigated in an estuarine habitat. The principal prey items included harpacticoids and palps of polychaetes in February and March and thereafter shifted to siphons of the bivalve Nuttallia olivacea from April to June. This seasonal change in diet occurred irrespective of body size, suggesting that other factors, such as morphological development of the predator or vulnerability of prey, induced the diet shift.
