Food Organisms of juveniles of Chaenogobius mororanus Inhabited at Intertidal Zone of the Western Coast of Korea

To investigate the food organisms of the Chaenogobius mororanus during the juveniles stage, the stomach contents of fish, captured in the intertidal zone of Chungchong- nam-do Sochon-gun Su-myon Dodun-ri (Fig. 1) between on early June from end of May 2003, were observed. Total length of the juveniles of C. mororanus was 5.0 mm ${\sim}$ 8.4 mm size, and the participation rate of feeding was 71.4%. Main food organisms were such as copepods, decapods, polychaete larvae, amphipods and these occupied more than dry weight 3.9%. Copepods among them dominated the most quantitys by average 62.0%, and next, food organisms appeared much by order of decapods, polychaete larvae and amphipods etc.. Therefore, most important food organisms of juvenile stage of C. mororanus were copepods, decapods, polychaete larvae, amphipods etc.
