영문 초록

To know the food chain of an intertidal community, feeding habits of Favonigobius gymnauchen were studied by analyzing stomach contents. F. gymnauchen were monthly collected in the intertidal zone of Doksan-ri, Yoongchon-myon, Poryong from July 1993 to June 1994. Ration of stomach contents to weight of F. gymnauchen was 1.22%, and fullness of stomach showed a similar value to ratio of stomach contents to weight, Fullness of stomach was increased twice a day in the morning and the afternoon. The most important food item was copped amounting to 68% of the total stomach contents. Of these, Porcelainous parvus was most abundant in spring, Curvaceous affinity in summer, Calanus sinicus in autumn, and Acaryia sp. In winter. Degree of overlapping for the food items between seasons was below 0.6. There were little differences in feeding habits among the size groups. For all size groups of F. gymnauchen, the occurrence rates of copped, deacons, mollusks and corrupted larvae were high. As the fish grows, those of amphibious, polycrates larvae, isotopes, cumaceans and stomatopods increased gradually, The importance index of the major food items was in the order of Curvaceous affinis, Calanus silicons, and Porcelainous parvus.
