Abstract

To investigate the food organisms of the Chasmichthys dolichognathus during the juveniles stage, the stomach contents of fish, captured in the intertidal zone of Chungchongnam-do Sochon-gun Su-myon Dodun-ri between on early June from end of May 1998, were observed. Total length of the juveniles of C. dolichognathus was 6.5mm ∼10.0mm size, and the participation rate of feeding was 67.7%. Main food organisms were such as copepods, amphipods, shrimp larvae, polychaete larvae, and these occupied more than dry weight 2%. Copepods among them dominated the most quantitys by avergage 65.5%, and next, food organismsms appeared much by order of polychaete larvae and shrimp larvae etc. Therefore, most important food organisms of juvenile stage of C. dolichognathus were copepods, polychaete larvae, shrimp larvae etc.
