The southern rough shrimp Trachysalambria curvirostris (Stimpson) was monthly sampled from the coastal area of Yeosu, Korea from June 2000 to May 2001 and its stomach contents were investigated. Mysids and amphipods were the most dominant prey, comprising >40% of the diet in both % occurrence and % abundance. In particular, mysids were most important food without regard to seasons, size classes, or sexes. The abundance and occurrence composition of food items showed a seasonal fluctuation: mysids and amphipods were the predominant prey items in spring (33.8%), summer (41.1%), autumn (43.9%), and winter (49.2%). For small-sized shrimps (＞25 mm CL), mysids and amphipods consist of more than 45% of its food in both % abundance and % occurrence. For large-sized shrimps (>25 mm CL), these were clearly dominant. The quantities and items of food did not differ in both genders, which mainly fed on mysids and amphipods. The trophic diversity and equality of diet varied with seasons and size classes. The diet diversity for smaller shrimps was highest in spring, while that for the larger shrimp lowest in winter. Also, the mandibular structure of Trachysalambria curvirostris indicates that the species is carnivorous.

Effect of artificial illumination on feeding by the rockfish Sebastes schlegeli receiving no synthetic feed in the cage of the Tongyong Marine Ranch was investigated by analysing the stomach contents of 20 individuals every month from October 1998 to July 1999. The fish was found to have fed on naturally available zooplanktons, i.e. Calanus sinicu, zoeae, amphipods and copepodites in October, fish larvae in November-December, nematodes in January, amphipods in February and again fish larvae from May to July. Despite increase in the weight of stomach contents from 260 mg/fish during the initial period of study to 2,173 mg/fish, as many as 70% of the fish were found to have empty stomach during March-April. Weight of stomach contents did not increase with increasing age of the fish. Occurrence frequency was 83-90% for C. sinicus during October-November and >50% for fish larvae during March-April and June-July.

조간대에서 서식하는 비늘흰발망둑의 섭식 생태를 파악하여 연안 생물 군집의 먹이 사슬에 관한 기초 지식을 얻고자, 1996년 7월부터 1997년 6월까지 충남 서천군 서면 도둔리에서 매월 1회씩 비늘흰발망둑을 채집하여 위 내용물 분석을 통해 섭식 생태를 조사하였다. 위 만복도는 하루 중 오전과 오후에 각각 한 차례식 증가하는 경향을 보였다. 비늘흰발망둑(1.2~5.9cm SL)의 주요 먹이생물은 십각류(유영류 유생, 젓새우, 보리새우 및 보행류 유생), 단각류(카프렐라류, 옆새우류 및 하이페리아류), 요각류(Acartia sp., Calanus sinicus, Corycaeus affinis 및 Microsetella sp.) 등으로 식성이 육식성이었다. 그 외 등각류, 만각류 유생, 다모류 유생 및 구각류 등이 소량씩 위 내용물 중에서 발견되었다. 비늘흰발망둑이 성장함에 따라 먹이생물의 조성비가 점차 변하였다. 체장이 작은 비늘흰발망둑은 요각류, 십각류 및 단각류 순으로 먹었으나, 체장이 증가하면서 요각류의 비율은 점차 낮아진 반면, 십각류와 단각류가 위 내용물 중 차지하는 비율은 점차 증가하였다.

오스트레일리아의 Queensland에 위치한 Cockle Bay의 해초지에서 채집된 Sillago maculata의 식성을 조사하였다. S. maculata (0.5~9.5 cm SL)의 주요 먹이생물은 단각류에 속하는 옆새우류, 게류 및 요각류였으며, 그 외 갯지렁이류, 새우류, 어류, 등각류, 쿠마류 등이 소량씩 위내용물 중에서 발견되었다. S. maculata은 성장함에 따라 먹이생물의 조성이 점차 변하였다. 체장이 작은 개체는 요각류, 게의 유생, 옆새우류를 주로 먹었으나, 체장이 증가하면서 요각류 및 게 유생의 비율은 점차 낮아진 반면, 갯지렁이류 및 어류가 차지하는 비율은 증가하였다. 한편 옆새우류는 조사된 모든 크기에서 가장 선호하는 먹이생물이었다.

Stomach contents of three commercially important species, anchovy (Engraulis japonica), small yellow croaker (Larimichthys polyactis) and yellow goosefish (Lophius litulon) were analyzed to investigate difference of prey between Spring and Fall. Trawl surveys for target fishes were conducted at 12 stations by the RV Tamgu-8 in the Yellow Sea-Korean side in Spring and Fall 2008 as a part of the United Nations Development Programme/Global Environment Facility (UNDP/GEF), Yellow Sea Large Marine Ecosystem (YSLME) survey. Stomach contents of 50 individuals of each species were analyzed to species level of prey, if the number of specimens was more than 50 for each species. Fullness and digestion condition of stomach contents were determined by five and six levels, respectively. In anchovy stomachs, 23 species in Spring and 15 species in Fall were identified, respectively. Stomach contents were mostly occupied by copepods and euphausiids, mostly Euphausia spp., calyptopis in Spring while by copepods and amphipods in Fall. In small yellow croaker stomachs, 23 species in Spring and 11 species in Fall were identified. Stomach contents were mostly occupied by copepods and euphausiids in Spring, but by only euphausiids in Fall. Total 368 yellow goosefish (151 in Spring and 217 in Fall) were captured, but stomach contents only in Fall were analyzed. Most of stomach contents were anchovy with small proportion of Hakodate sand shrimp, Tanaka's snailfish, Pacific cod, and miscellaneous things. The present research unveiled that main food items of plankton feeder were distinctly different by species and seasons in the Yellow Sea-Korean side, as coincided with previous reports.

광양만 대도주변 잘피밭에서 채집된 복섬 유어의 식성을 조사하였다. 복섬 (2$\~$8 cm SL)의 주요 먹이생물은 단각류 (옆새우류 및 카프렐라류), 게류 및 새우류 둥의 갑각류와 복족류였다. 그 외 갯지렁이류, 요각류, 주걱벌레붙이류, 등각류 등이 소량씩 위내용물 중 발견되었다. 복섬이 성장함에 따라 먹이생물의 조성이 점차 변하였다. 체장이 작은 복섬은 옆새우류, 카프렐라류 및 복족류를 주로 먹었으나, 체장이 증가하면서 옆새우류 및 복족류의 비율은 점차 낮아진 반면, 게류 및 새우류가 위내용물 중 차지하는 비율은 증가하였다.

To understand feeding habits of Cheaenogobius mororanus, this study has been conducted by analyzing stomach contents. C. mororanus were monthly collected from the intertidal zone of Dodun-ri, Sochon from May 1997 to April 1998. Fullness of stomach was increased twice a day, in the morning and afternoon. C. mororanus(1.0 ∼5.9 cm in standard length) was a carnivores consuming mainly decapods, amphipods and copepods. (omitted)

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.

To investigate the food organisms of the Acanthogobius hasta 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 A. hasta was 5.5 mm ${\sim}$ 8.9 mm size, and the participation rate of feeding was 69.6%. 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 62.7%, and next, food organisms appeared much by order of decapods, polychaete larvae and amphipods etc.. Therefore, most important food organisms of juvenile stage of A. hasta were copepods, decapods, polychaete larvae, amphipods etc.
