  • Feeding habits of Pseudoblennius percoides collected from the eelgrass bed in Dongdae Bay from January to December 2005 were studied. P. percoides was a carnivore which mainly consumed fishes and caridean shrimps. Its diets included small quantities of mysids,amphipods (gammarid amphipods and caprellid amphipods), copepods, cephalopods, polychaetes,and crabs. P. percoides undergoes significant size-related changes; smaller fish (<3.0 cm SL) prey mainly copepods, gammarid amphipods, and mysids while the proportion of caridean shrimps and fishes increases with fish size. Fishes and caridean shrimps were major prey organisms for all seasons. Dietary breadth of P. percoides was lower with fish size and seasons.

  • Feeding habits of Sillago japonica collected from in an eelgrass (Zostera marina) bed in Jindong Bay, Korea were studied. S. japonica was a carnivore which consumed mainly gammarid amphipods, polychaetes, bivalves, caridean shrimps and crabs. Its diets also included a small amount of fishes, copepods and caprellid amphipods. The diet of S. japonica underwent significant size-related changes; small individuals (<5cm SL) fed mainly on gammarid amphipods and crab larvae, while proportion of polychaetes and bivalves increased with increasing fish size and gammarid amphipods were also important prey for medium size individuals (5.1-9.9cm SL). The large individuals (>10cm SL) ate polychaetes, caridean shrimps and crabs. The dietary breadth of S. japonica were varied with size. The diet of S. japonica also underwent seasonal changes that could be related to differences in prey availability; gammarid amphipods were mainly consumed in spring and polychaetes in summer.

  • Feeding habits of Acentrogobius pellidebilis collected from in an eelgrass(Zostera marina) bed from January to December 2006 were studied. A. pellidebilis ranged form 1.6 to 6.9 cm in standard length were determined. A. pellidebilis was a carnivore which consumed mainly copepods, polychaetes, and amphipods. Its diets included small quantities of isopods, seaweeds, nematods, and gastropods. It showed ontogenetic changes in feeding habits. Smaller individuals (<2.0cm SL) fed mainly on copepods. While the consumption of copepods decreased with increasing fish size, the consumption of polychaetes and amphipods were increased. Dietary breadth index was varied with fish size.

  • Feeding habits of Hippocampus mohnikei (4.1~10.4 cm SL) collected from an eelgrass bed in Dongdae Bay, Korea were studied. H. mohnikei was a carnivore fish which consumed mainly gammarid amphipods. Its diets also included a small amount of caprellid amphipods, tanaids, copepods, mysids, and eelgrass. Gammarid amphipods were the most important prey organisms to the diet of all size classes of H. mohnikei despite smaller H. mohnikei (<4.5 cm SL) fed copepods. H. mohnikei fed on larger sizes of prey as their size increased. The dietary breadth of H. mohnikei were decreased with increasing their size.

  • Feeding habits of juvenile Liparis tanakai collected from the eelgrass bed in Kwangyang Bay were studied. L. tanakai (2.0-6.0 cm SL) was a carnivore which consumed mainly amphipods (caprellids and gammarids) and caridean shrimps. Its diets also included a large amount of copepods, polychaetes and small fishes. Three distinct ontogenetic feeding groups were noted: (1) the individuals of 2.0-2.5 cm SL preyed heavily on copepods, (2) individuals of 2.5-4.0 cm SL fed mainly on amphipods. (3) individuals over 4.0 cm SL preyed mainly on caridean shrimps and small fishes. The dietary breadth of each size class showed relatively low value, and this means that juvenile L. tanakai depends on only few kinds of food organisms.

  • Feeding habits of Limanda yokohamae collected from the eelgrass bed in Kwangyang Bay were studied. L. yokohamae (1-16 cm SL) was a carnivore which consumed mainly polychaetes. Its diets included a significant quantity of amphipods (gammarids and caprellids) as well as small quantities of gastropods and ophiuroids. L. yokohamae showed ontogenetic changes in feeding habits. Small individuals less than 4 cm SL preyed mainly on amphipods. However, polychaetes were heavily selected with increasing fish size while the portion of the diet attributable to amphipods decreased sharply. Polychaetes were the major prey organisms for all seasons. Dietary breadth of each size class shows relatively low value, and this means that L. yokohamae depends on only few kinds of food organisms.

  • Feeding habits of Rudarius ercodes collected from a Zostera marina bed in Jindong Bay, Korea were studied. R. ercodes was a omnivore which consumed mainly gammarid amphipods, polychaetes and eelgrass (z. marina). Its diets also included a small amount of copepods, urochordates and caprellid amphipods. R. ercodes showed ontogenetic changes in feeding habits. Small individuals less than 2cm SL fed mainly on copepods, however, gammarid amphipods and polychaetes were heavily selected with increasing fish size. The consumption of eelgrass by R. ercodes was $10-20\%$ all size classes. The dietary breadth of R. ercodes were varied with fish size

  • In this study, problems with table serving of Korean Jeollanamdo food were investigated, and methods for improvement were suggested. The manner of food serving and arrangement on tables, as well as the serving space in each case, were investigated in representative restaurants serving Jeollanamdo food. The results showed that most of the Jeollanamdo Korean food have a prototype of a flat serving sprea, wherein the main dish and side dishes are not clearly identified, the demarcation between shared space and personal space is insufficiently made for each serving on the table, and the table is full of side dishes, that are narrow, visually disordered and unhygienic, both in terms of the table setting and arrangement inside bowls. To provide sufficient eating space, elevate awareness of hygienic and clean serving, and identifying the main dish in the table setting, a serving method that is a compromise between the flat spread-out and time-series development was suggested, and an arrangement on the table was defined for the main dish and side dishes. The utilization of table space was also increased by reducing the number of dishes on the table at a given moment. In addition, the dish or bowl and arrangement inside the container were changed in order to distinguish the main dish and side dishes. It is suggested that some of tableware be linked with the special products of the locality so as to make a brand for them, and that a personal mat be used to arrange the tableware for each one, since there are many fermented food items (salted fish, kimchi, fermented paste and sauce, etc.) and boiled food items (stew, steamed dish, boiled dish in sauce, etc) that look dark and unfocused. In addition, it is suggested that the width and breadth of the dishes or bowls be set in an orderly manner. Considering the tables currently available at restaurants, personal space on a table and comfortable distance between eaters are suggested to be $400 mm{\times}250 mm$ and 300 mm, respectively.

  • A total of 164 individuals of Hippocampus coronatus were collected from an eelgrass bed in Dongdae Bay, Korea from September 2006 to August 2007. The number of individuals of H. coronatus was higher in September 2006. The size of H. coronatus ranged from 2.4 to 9.3cm in height (Ht), and most of individuals were small size below 5cm (Ht). H. coronatus was a carnivore which consumed mainly gammarid amphipods and copepods. Its diets also included a small amount ofmysids, ostracods, brachiopods, caprellid amphipods, bathynellaceas, isopods, tanaids, and ascothoracids. The diets of H. coronatus underwent size-related changes; smaller individuals consumed copepods, while larger individuals ate gammarid amphipods and mysids. The dietary breadth index of H. coronatus was increased with increasing of their size.

  • The feeding habits of Sebastes schlegeli collected from the Tongyeong marine ranching area throughout 2002 were studied. S. schlegeli is a carnivore (piscivore), and consumed mainly fish. Its diet also included a small amount of caridean shrimps, crabs, amphipods, polychaetes, and isopods. The diet of S. schlegeli underwent size-related changes. Small individuals (standard length (SL)<6 cm) fed mainly on fishes, caridean shrimps, and amphipods, and the proportion of fish increased with SL. Large individuals (SL>20 cm) ate fish predominately. The diet of S. schlegeli changes seasonally, and caridean shrimps were consumed mainly from May to July. The dietary breadth index of S. schlegeli varied with SL and season.
