The feeding habits of olive flounder, Paralichthys olivaceus were studied using 126 specimens collected from coastal waters off Taean, Korea from April 2008 to March 2009. The total lengths of P. olivaceus ranged from 16.7 to 40.6 cm. P. olivaceus was a piscivore that consumed mainly fishes. The diet also included small quantities of shrimps, cephalopods, polychaetes and mysids. Although, P. olivaceus mainly consumed fishes of all size classes, some degree of change in diet composition was found; i.e. after fishes, smaller individuals fed more on shrimps, whereas larger individuals consumed more cephalopods.

The feeding habits of Sebastiscus marmoratus collected from the Western Coastal Waters of Jeju Island between June 2008 and July 2009 were studied based on examination of the stomach contents. A total 254 individuals of S. marmoratus ranged from 13.2 to 29.6cm (mean 20.7cm) in Standard length (SL). S. marmoratus consumed mainly teleosts such as Chromis notata and Sebastes inermis. Its diet also includes shrimps and crabs. The individuals smaller than 15cm SL consumed mainly shrimps, but on the other hand the individuals larger than 25cm SL consumed mainly fishes. The proportion of fish consumption increased with increasing size of S. marmoratus.

This study investigated the concentration of total mercury in 17 species of commonly consumed fishes and assessed the risk to human health from provisional tolerable weekly intakes PTWI% as affected by migratory characterization, such as migration and vagility. The measured mean concentrations of total mercury in these 17 species of commonly consumed fishes suggest that mean concentrations of total mercury in 10 species of migratory fishes (largehead hairtail, chub mackerel, Pacific saury, skipjack tuna, Pacific cod, anchovy, Alaska pollack, brown croaker, Japanese Spanish mackerel, yellow croaker and Pacific herring) were low compared to those in 7 species of demersal fishes (red stingray, brown sole, bastard halibut, conger eel, blackmouth angler, rockfish and filefish). Based on the mean concentrations, the PTWI% of total mercury among commonly consumed migratory fishes was 3.393%, which was higher than that of commonly consumed demersal fishes (2.710%).

The feeding habits of brown barracuda (Sphyraena pinguis) were analyzed using the stomach contents of monthly samples collected from coastal waters of Gadeok-do, Korea from January to December, 1998. Brown barracuda occurred mainly from summer to autumn in the study area, and ranged from 15 to 35 cm in standard length. Brown barracuda was a piscivorous fish which, mainly consumed teleost fish such as anchovy (Engranlis japonicus) and chefoo thryssa (Thfssa kammalensis). Its diet also included small quantities of shrimp and cephalopods. Although smaller fishes (<25 cm SL) consumed shrimp and cephalopods as well as fish, larger fishes (>30 cm SL) consumed exclusively teleost fish. The prey size increased with increase of fish size.

The feeding habits of scorpion fish, Sebastiscus marmoratus, were studied using 324 specimens collected in the coastal waters of Tongyeong, from January to December, 2009. The size of the specimens ranged from 9.8 to 30.1 cm in standard length (SL). S. marmoratusis was a piscivore that consumed mainly teleosts such as Engraulis japonicus, Clupea pallasi and gobid fishes. Of the fish species Engraulis japonicus was the most preferred prey. Its diet also includes shrimps and crabs. Hermit crabs, polychaetes, bivalves and euphausia were minor preys. Smaller individuals (<13 cm SL) fed mainly on shrimps, crabs and fishes. The proportion of shrimps and crabs decreased as body size increased, whereas the consumption of fishes gradually increased. Fishes accounted for almost stomach contents of larger individuals (more than 19 cm SL). Seasonal changes in the S. marmoratusis diet were significant. Fishes was most common prey during summer, autumn and winter, whereas crabs and shrimps were mainly consumed during spring.

This study determined the concentrations of lead and cadmium in 18 species of commonly consumed fish and assessed the risk based on provisional tolerable weekly (monthly) intakes [PTW(M)I] % as affected by behavioral characteristics, such as migration and settlement. In the 18 species, the mean concentrations of lead and cadmium were higher in the 11 species of migratory fish (llargehead hairtail Trichiurus lepturus, chub mackerel Scomber japonicus, Pacific saury Cololabis saira, skipjack tuna Katsuwonus pelamis, Pacific cod Gadus macrocephalus, anchovy Engraulis japonicus, Alaska pollack Theragra chalcogramm, brown croaker Miichthys miiuy, Japanese Spanish mackerel Scomberomorus niphonius, yellow croaker Larimichthys polyactis, and Pacific herring Clupea pallasii) than in the seven demersal species (red stingray Dasyatis akajei, brown sole Pleuronectes herzensteini, bastard halibut Paralichthys olivaceus, conger eel Conger myriaster, blackmouth angler Lophiomus setigerus, rockfish Sebastes schlegelii, and filefish Stephanolepis cirrhifer). Based on the mean concentrations, the PTWI % of lead and cadmium in commonly consumed migratory fish were 1.900 and 2.986%, respectively, which were higher than the values for lead and cadmium in the commonly consumed demersal fishes (0.257 and 0.318%, respectively). The estimation of weekly (monthly) intakes and target hazard quotients for the toxic elements lead and cadmium revealed that the commonly consumed migratory and demersal fish do not pose any health risks for consumers.

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 Pseudoblennius cottoides collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. Pseudoblennius cottoides was a carnivore which mainly consumed fishes, caridean shrimps, and amphipods. Its diets included small Quantities of tanaids, copepods, isopods, mysids, and polychaetes. It showed ontogenetic changes in feeding habits. Fishes were heavily selected as the body size of P. cottoides increases. Fishes and caridean shrimps were major prey organisms for all 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 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.
