  • Feeding habits of juvenile Acanthopagrus schlegeli collected from the eelgrass bed in Kwangyang Bay were studied. A. schlegeli (1~7cm SL) was a carnivore which consumed mainly amphipods (gammarid and caprellid amphipods), crabs and shrimps. Its diets included small quantities of gastropods, polychaetes, hydroids, tanaids, copepods and isopods. A. schlegeli showed ontogenetic changes in feeding habits. Small individuals preyed mainly on gammarid amphipods, gastropods and polychaetes. However, crabs and shrimps were heavily selected with increasing fish size.

  • Feeding habits of juvenile Takifug niphobles collected from the eelgrass bed in Kwangyang Bay were studied. T. niphobles (2$\~$8 cm SL) was a carnivore which consumed mainly amphipods (gammarid and caprellid amphipods), crabs, shrimps and gastropods. Its diets included minor quantities of polychaetes, copepods, tanaids and isopods. T. niphobles showed ontogenetic changes in feeding habits. Small individuals preyed mainly on gammarid amphipods, caprellid amphipods and gastropods. However, crabs and shrimps were heavily selected with increasing fish size.

  • Feeding habits of Favonigobius gymnauchen collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. Favonigobius gymnauchen was a carnivore which consumed mainly gammarid amphipods, polychaetes, crabs and copepods. Its diets included minor Quantities of gastropods, tanaids and isopods. It showed ontogenetic changes in feeding habits. Small individuals (1$\~$2 cm) fed mainly on gammarid amphipods, polychaetes, and copepods. While the portion of the stomach contents attributable to polychaetes and crabs increased steadily with incensing fish size, consumption of copepods decreased progressively. Gammarid amphipods were the most selected prey item for all size classes. Although gammarid amphipods, polychaetes, crabs and copepods were major prey organisms for all seasons, the relative proportion of these food items changed with season. Consumption of copepods was relatively high in spring and fall and consumption of gammarid amphipods, polychaetes and crabs was relatively high in summer.

  • 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.

  • Feeding habits of Zoarces gilli collected in the coastal water off Gadeok-do, Korea from March 1998 to February 1999 were studied. Z. gilli was a carnivore and consumed mainly shrimps, gammarid amphipods, fishes, bivalves and cumaceans. Its diets also included small quantities of copepods, caprellid amphipods, ostracods, crabs, squids, gastropods, ophiuroids and polychaetes. It showed ontogenetic changes in feeding habits. Individuals of small size (10~15 cmSL) fed mainly on small prey organisms such as gammarid amphipods, bivalves, cumaceans and ostracods. However, larger shrimps and fishes were heavily selected with increasing fish size.

  • Feeding habits of juvenile Sillago maculata, collected from the tropical seagrass beds in Cockle Bay, Queensland, were studied. S. maculata (0.5~9.5 cm SL) was a carnivore which consumed mainly gammarid amphipods, crabs and copepods. Its diets included small quantities of polychaetes, shrimps, fishes, isopods and cumacean. S. maculata showed ontogenetic changes in feeding habits. Small individuals preyed mainly on copepods, crab larvae and gammarid amphipods. While the portion of the stomach contents attributable to polychaetes, crabs and fishes increased with increasing fish size, consumption of copepods and crab larvae decreased progressively. Gammarid amphipods were the most selected prey item for all size classes.

  • Feeding habits of Conger myiaster collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. C. myiaster was a carnivore which consumed mainly fishes, shrimps and crabs. Its diets included small quantities of amphipods, gastropods, cephalopods, polychaetes, mysids, cumaceans and isopods. It showed ontogenetic changes in feeding habits. Small indinviduals preyed on shrimps, fishes, crabs, and gammarid amphipods in nearly equal proportions. While the portion of the stomach contents attributable to shrimps and gammarid amphipods decreased with increasing fish size, consumption of fishes increased progressively. C. myiaster showed very constant prey selection regardless of prey availability-Especially fishes were heavily selected by this species throughout the year, although availability of fishes was lower than any other prey organisms in the eelgrass bed.
