  The Kuroshio Extensition area is an important nursery grounds of larvae and juvenile fish of Pacific saury, Cololabis saira. The present study conducted the oceanographical observation in the Kuroshio Extension area between 140E to 155W by a research ship to clarify the spatio-temporal change of nutrient and plankton and also investigate the geographical variation of feeding and growth of Pacific saury larvae. The present study showed that the abundance of main prey (Calanoid copepods) for Pacific saury larvae were different by the ocean environments in response to the geographical change of the current speed and meandering. These results indicated that prey environments of larvae were influenced by the current, suggesting the survival rate of larva was influenced by such spatio-temporal change of ocean environment.
