Feeding habits of Pholis nebulosa collected from a eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. Pholis nebulosa was a carnivore which mainly consumed epiphytal amphipods. Its diets included minor quantities of caridean shrimps, isopods, copepods, tanaids and polychaetes. It showed ontogenetic changes in feeding habits. In an initial feeding stage, copepods were major food organisms. However, gammarid and caprellid amphipods were heavily selected with increasing fish size. Although gammarid and caprellid amphipods were major prey organisms for all seasons, the relative proportion of these two food items changed with season.

Stomach contents of snailfish, Liparis tanakai, caught in the Nakdong River Estuary were examined quantitatively. Liparis tanakai was a bottom feeding carnivores, and showed an almost strict specialization on shrimps and fishes. Shrimps and fishes accounted for 74.3% and 19.8% of the overall stomach contents, respectively. The most selected prey species was Cragon affinis for all fish size classes. The snailfish' s diets included minor quantities of crabs, amphipods, mysids and isopods. Small individuals(4~10 cm SL) consumed mainly shrimps which accounted for approximately 90% of the stomach contents. However, the portion of the diet attributable to shrimps decreased steadily with increasing fish size, and this decrease was paralleled by increased cosumption of fishes. For 31~45 cm individuals, fishes constituted over 30% of the stomach contents, while shrimps made up approximately 60% of the diet.
