Feeding habits of Lateolabrax Japonicus collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. L. Japonicus was a carnivore which consumed mainly amphipods (gammarid amphipods and caprellid amphipods), crabs, caridean shrimps and copepods. Its diets included small quantities of fishes, mysids, polychaetes, tanaids and isopods. Three distinct ontogenetic feeding groups were noted : (1) 1~2 cm SL individuals preyed heavily on copepods. (2) 2~15 cm SL individuals preyed heavily on amphipods. (3) individuals over 15 cm SL preyed heavily on crabs, caridean shrimps and fishes. L. Japonicus showed seasonal changes in prey composition. These changes were not caused by seasonal changes in food availability, but by changes in the size composition of L. Japonicus occurred in the eelgrass bed.

We examined the stomach contents of juvenile Lophius litulon, which were collected monthly in the coastal waters of Kori, Korea from January to December, 1996. L. litulon was a bottom feeding carnivore which mainly consumed fish, euphausiids, sagittoids, and shrimp. Its diet also included small quantities of copepods amphipods, and stomatopods. It showed distinct ontogenetic changes in feeding habits. Small individuals (1-2 cm SL) mainly preyed on sagittoids and euphausiids. However, individuals eve, 3 cm SL mainly preyed on fish and shrimp.

We examined the feeding habits of larval Konosirus punctatus using 165 specimens collected from May to August 2011 in the Nakdong River estuary, Korea. We found that larval K. punctatus [3.9-8.4 mm notochord length (NL)] are carnivorous, consuming mainly rotifers. Their diet also included small numbers of rhizopods, tintinnids, euglenoids, copepods, larval bivalves, dinoflagellates, diatoms, and unidentified materials. To evaluate ontogenetic changes in dietary composition, we split the larvae into three size groups: < 5 mm, 5-6 mm, and > 6 mm NL. The smallest size group frequently preyed on rhizopods. As NL increased, the number of rotifers increased relative to those of rhizopods. Larvae also showed bimodal feeding for feeding incidence, with peaks in the midafternoon and at midnight, while the mean number of prey per individual peaked at 18:00-19:00 h.

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.

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.

2004년 1월부터 12월까지 부산 주변해역에서 채집된 참돔의 식성을 조사하였다. 참돔의 체장분포는 8.5~44.6 cm SL의 범위였다. 참돔의 주요 먹이생물은 집게류 (Anomura), 단각류 (Amphipoda), 게류 (Brachyura), 새우류 (Caridea), 갯지렁이류 (Polychaeta), 극피동물 (Echinodermata), 어류(Pisces) 등 매우 다양했다. 그 외, 복족류(Gastropoda), 이매패류(Bivalvia), 갯가재류(Stomatopoda), 두족류(Cephalopoda) 자포동물(Cnidaria), 등각류(Isopoda) 등도 소량 섭이하였다. 참돔은 성장함에 따라 먹이생물 조성에 있어 변화를 보였는데, 체장 8~15 cm SL에서 새우류의 점유율이 높았으며, 15~25 cm SL에서는 집게류와 갯지렁이류의 점유율이 높았다. 그리고 25 cm SL 이상에서는 극피동물류와 어류의 점유율이 높게 나타났다.

The feeding habits of the Japanese jack mackerel Trachurus japonicus were studied in the Southern Sea of the Republic of Korea. To assess the effects of season, sampling was conducted in February (winter), May (spring), and August (summer), 2020. The total length of each fish was measured in 1 cm intervals. Diet composition showed the highest species diversity during winter. Diet composition changed from copepods to euphausiids as the total length of jack mackerel increased, except during winter. The most important seasonal prey were copepods in winter and summer and euphausiids in spring. Species diversity of the zooplankton community structure was highest in winter. Among the zooplankton communities, copepods were dominant in all seasons. Species with a high electivity index in all seasons were relatively large zooplankton of ≥2 mm. Jack mackerel had ontogenetic diet change, exhibited diet selectivity depending on size, and its feeding habits were affected by the zooplankton community structure.

The feeding habits of larval (5.0~27.0 mm SL) Clupea pallasii were examined and 1,523 individuals were collected from November 2010 to March 2011 in the coastal water of Eastern Jinhae Bay, Korea. Larval C. pallasii were fed mainly on copepods that constituted 55.2% in IRI. Monogeneans were the second largest prey component, another prey items tintinnids, cladocerans and ostracoda. The results of analysis in ontogenetic changes exhibit high during the daytime, two small size classes (${\leq}10mm$, 10~15 mm) mainly fed copepods. while the percentage of coperpods decreased, monogeneans ratio increased in 15~20 mm size class. Feeding rate in diel difference of larval C. pallasii were high during the daytime.

We examined the feeding habits of larval Clupea pallasii using 148 specimens collected from December 2010 to April 2011 in the Nakdong River estuary, Korea. We found that larval C. pallasii [8.3-26.0 mm NL (notochord length)] are carnivorous, consuming mainly copepods, rotifers, cirripeds, and free-living flatworms (Macrostomida). Their diet also include small quantities of shrimp nauplii, tintinnids, cladocerans, and larval bivalves, among other food sources. To evaluate ontogenetic changes in dietary composition, we split larvae into four size groups: 8-12 mm, 12-16 mm, 16-20 mm, and > 20 mm NL. Rotifers were the most important prey items for the smallest group, but all other groups predominantly consumed copepods. The largest group frequently preyed on rotifers, cirripeds and flatworms, in addition to copepods. Larvae also showed bi-modal feeding, with peaks in the late afternoon and at midnight, wherein the mean number of prey per individual peaked at 1,800-1,900 h.
